EPS-HEP 2017 Report of Contributions EPS-HEP 2017 Report of Contributions https://indico.cern.ch/e/epshep2017 EPS-HEP 2017 / Report of Contributions Theory overview on FCNC B-decays Contribution ID: 10 Type: Parallel Talk Theory overview on FCNC B-decays Thursday, 6 July 2017 09:00 (30 minutes) LHCb experiment at CERN has recently reported a set of measurements on lepton flavour univer- sality in b to s transitions showing a departure from the Standard Model predictions. I will review the main ideas recently put forward to make sense out of these intriguing hints. Focusing on the new physics explanation, I will discuss the correlated signals expected in other low- and high- energy observables, that could help clarify the mysterious signal.

Only experimental data for the charm resonances below the continuum threshold are needed in our approach, while the continuum contribution is determined by requiring self-consistency between various sum rules, including the one for the ze- roth moment. Existing data from the continuum region can then be used to bound the theoretical error. Our result is mc(mc) = 1272 ± 8 MeV for αs(MZ ) = 0:1182. Special attention is given to the question how to quantify and justify the uncertainty.

It started data taking at the LHC at a centre-of-mass energy of 13 TeV, in 2015. Its ground breaking physics program defines a number of scenarios that yield potentially revolutionary insights into such foundational questions as: are there extra dimensions or new symmetries; what is the mechanism for the generation of mass; does magnetic charge exist; and what is the nature of dark matter. MoEDAL purpose is to meet such far-reaching challenges at the frontier of the field. We will present the first results from the MoEDAL detector on Magnetic Monopole production that are the world’s best for Monopoles with multiple magnetic charge. In conclusion, plans to install a new MoEDAL sub-detector de- signed to search for very long-lived neutral particles as well as mini-charged particles will be very briefly discussed.

The international Muon Ionization Cooling Experiment (MICE) will demonstrate ionization cooling the technique by which it is proposed to reduce the phasespace volume occupied by the muon beam. MICE is being constructed in a series of Steps. The configuration currently in operation at the Rutherford Appleton Laboratory is optimised for the study the properties of liquid hydrogen and lithium hydride that affect cooling. The data taken in the present configuration have been partially ana- lyzed and the available results will be described in detail.

The international Muon Ionization Cooling Ex- periment (MICE) will demonstrate muon ionization cooling, the technique proposed to reduce the phases- pace volume occupied by the muon beam at such facilities. In an ionizationcooling channel, the muon beam traverses a material (the absorber) loosing energy, which is replaced us- ing RF cavities. The combined effect is to reduce the transverse emittance of the beam (transverse cooling). The configuration of MICE required to deliver the demonstration of ionization cooling is presently being prepared in parallel to the execution of a programme designed to mea- sure the cooling properties of liquidhydrogen and lithium hydride (Step IV). The design of this final cooling demonstration will be presented together with a summary of the performance of each of its components and the cooling performance of the experiment.

This is in agreement with the value 0f 441~MeV inthe modern constituent quark model (NRCQM, by L.Glozman et al.) where it is determined as 1/3 of the mass of Ξ-octet hyperon. Earlier the discreteness in mass values of nucleons, the muon, the pion and other particles with the period of 16 electron masses (the period of δ=16me and numbers n=13, 17 etc. for the muon, the pion and the other particles) was found out from the analysis of exactly known relation between nucleon masses and the electron mass (CODATA relation) [1]. For an independent check of the empirical relations (found earlier by Y.Nambu, A.Hautot, G.Mac-Gregor and others) particle masses from recent Particle Data Group (PDG) 2016 compilation was performed. On the distribution of all differences between 140 particles known with accuracy better than 5 MeV the grouping effect of masses of the pion, themuon and the constituent quark (445-460 MeV) was confirmed. The stability of mass-intervals in the region of the bottom-quark mass is discussed.\\ 1. S.I.Sukhoruchkin, Nucl. Part. Phys. Proc. 270-272 (2016) 211.

Scalar contributions with the simultaneous presence of both left- and right-handed couplings to quarks can explain the available data, specifically R(D(∗)) together with the measured differential distributions. However, the constraints from the total Bc width present a slight tension with the current data on B→D∗τν in this scenario, preferring smaller values for R(D∗). I discuss possibilities to disentangle scalar new physics from other new-physics scenarios like the presence of only a left-handed vector cur- rent, via additional observables in B→D(∗)τν decays or additional decay modes like the baryonic Λb→Λcτν and the inclusive B→Xcτν decays. We also analyze scalar contributions in b→uτν transitions, including the latest measurements of B→τν, providing predictions for Λb→pτν and B→πτν decays. The potential complementarity between the b→u and b→c sectors is finally in- vestigated once assumptions about the flavour structure of the underlying theory

  • The Moedal Experiment at the LHC. Searching Beyond the Standard
    126 EPJ Web of Conferences , 02024 (2016) DOI: 10.1051/epjconf/201612602024 ICNFP 2015 The MoEDAL experiment at the LHC Searching beyond the standard model James L. Pinfold (for the MoEDAL Collaboration)1,a 1 University of Alberta, Physics Department, Edmonton, Alberta T6G 0V1, Canada Abstract. MoEDAL is a pioneering experiment designed to search for highly ionizing avatars of new physics such as magnetic monopoles or massive (pseudo-)stable charged particles. Its groundbreaking physics program defines a number of scenarios that yield potentially revolutionary insights into such foundational questions as: are there extra dimensions or new symmetries; what is the mechanism for the generation of mass; does magnetic charge exist; what is the nature of dark matter; and, how did the big-bang develop. MoEDAL’s purpose is to meet such far-reaching challenges at the frontier of the field. The innovative MoEDAL detector employs unconventional methodologies tuned to the prospect of discovery physics. The largely passive MoEDAL detector, deployed at Point 8 on the LHC ring, has a dual nature. First, it acts like a giant camera, comprised of nuclear track detectors - analyzed offline by ultra fast scanning microscopes - sensitive only to new physics. Second, it is uniquely able to trap the particle messengers of physics beyond the Standard Model for further study. MoEDAL’s radiation environment is monitored by a state-of-the-art real-time TimePix pixel detector array. A new MoEDAL sub-detector to extend MoEDAL’s reach to millicharged, minimally ionizing, particles (MMIPs) is under study Finally we shall describe the next step for MoEDAL called Cosmic MoEDAL, where we define a very large high altitude array to take the search for highly ionizing avatars of new physics to higher masses that are available from the cosmos.

Abstract The Large Hadron Collider is a large particle accelerator at the CERN research labo- ratory, designed to provide particle physics experiments with collisions at unprece- dented centre-of-mass energies. For its second running period both the number of colliding particles and their collision energy were increased. To cope with these more challenging conditions and maintain the excellent performance seen during the first running period, the Level-1 trigger of the Compact Muon Solenoid experiment — a so- phisticated electronics system designed to filter events in real-time — was upgraded. This upgrade consisted of the complete replacement of the trigger electronics andafull redesign of the system’s architecture. While the calorimeter trigger path now follows a time-multiplexed processing model where the entire trigger data for a collision are received by a single processing board, the muon trigger path was split into regional track finding systems where each newly introduced track finder receives data from all three muon subdetectors for a certain geometric detector slice and reconstructs fully formed muon tracks from this.

    Division of particle physics and astrophysics 2017-2020 The research fields of PAP form a continuum from experimental and theoretical particle physics through theoretical and observational cosmology, astrophysics, and solar system physics to space physics involving solar activity and its consequences in the solar system. The PAP research belongs to the University of Helsinki strategic research area Matter and Materials. In the Division the fundamental constituents of matter, as well as matter in extreme conditions is studied. Theoretical particle physics belongs also largely to the University spearhead Mathematics. Consequently physics department and department of mathematics and statistics have a common university lecturer. Both departments also take part in a common Master’s programme, Theoretical and Computational Methods. High-luminosity operation of the Large Hadron Collider (LHC), which is the main particle physics infrastructure we use, has been identified as the highest priority in the latest European Particle Physics Strategy (see http://cds.cern.ch/record/1551933/files/Strategy_Report_LR.pdf). Research at CERN is included in the Finnish Research Infrastructure Roadmap. Within the existing research programme we will exploit the synergy between the groups in particle physics and cosmology. We also aim to strengthen the links between observational cosmology and astrophysics. The most urgent personnel need is identified to be a university researcher position in observational cosmology (EUCLID). Other positions to be filled, resources permitting, are a tenure-track professorship in particle physics instrumentation, a tenure-track professorship in planetary research, and a tenure track position in particle theory. During next eight years professor positions in experimental particle physics, cosmology, and space physics will become vacant due to retirements.

  • Summary of Scientific Issues, CERN Council Week, Mar 22-26, 2021
    ================================================================ Summary of scientific issues, CERN Council week, Mar 22-26, 2021 By G. Dissertori, 07.04.2021 ================================================================ This was the 202nd meeting of the CERN Council; because of the still difficult Covid- 19 situation, it had to be held again by video-conference. Members of the CERN management gave reports in the meetings of the Scientific Policy Committee (SPC), the Restricted and Closed Sessions of the Council. Below a summary is provided, closely following the report issued by the SPC. An overview of the main items discussed and decided during this 202nd session of the Council can be found here: https://council.web.cern.ch/en/content/news Report by the Director General (DG, Fabiola Gianotti) The DG’s description of the efforts to control the detrimental effects of the Corona virus emphasised the care with which the situation has been managed. In particular, CERN has made major efforts to mitigate the impact of travel restrictions on all levels. Several institutes have been able to send people to CERN to assist in the preparation of the experiments (especially LHCb). The DG described the recent ICFA meeting and the evolution of the ILC International Development Team, in which CERN staff participate. The Pre-Lab proposal document is expected to be completed in ~1 month. She mentioned an intent by the ICFA’s Chair, Stuart Henderson, to send a letter to Minister Hagiuda ”encouraging” MEXT (the Japanese Ministry of Education, Culture, Sports, Science and Technology) to invite foreign government officials to discuss potential commitments to the ILC. The DG also reported on the signature of an agreement regarding participation by the US Department of Energy in the Future Circular Collider (FCC) Feasibility Study.

  • The Moedal Experiment at the LHC—A Progress Report †
    universe Communication The MoEDAL Experiment at the LHC—A Progress Report † James Lewis Pinfold ‡ Physics Department, University of Alberta, Edmonton, AB T6G 0V1, Canada; [email protected] † This paper is based on the talk at the 7th International Conference on New Frontiers in Physics (ICNFP 2018), Crete, Greece, 4–12 July 2018. ‡ On behalf of the MoEDAL Collaboration. Received: 8 January 2019; Accepted: 21 January 2019; Published: 29 January 2019 Abstract: MoEDAL is a pioneering LHC experiment designed to search for anomalously ionizing messengers of new physics. It started data taking at the LHC at a center-of-mass energy of 13 TeV, in 2015. Its ground breaking physics program defines a number of scenarios that yield potentially revolutionary insights into such foundational questions as: Are there extra dimensions or new symmetries? What is the mechanism for the generation of mass? Does magnetic charge exist? What is the nature of dark matter? After a brief introduction, we report on MoEDAL’s progress to date, including our past, current and expected future physics output. We also discuss two new sub-detectors for MoEDAL: MAPP (Monopole Apparatus for Penetrating Particles) now being prototyped at IP8; and MALL (Monopole Apparatus for very Long Lived particles), currently in the planning stage. I conclude with a brief description of our program for LHC Run-3. Keywords: collider physics; monopoles; high ionizing particles; fractionally charged particles; massive stable charged particles; very long-lived particles 1. Introduction MoEDAL (Monopole and Exotics Detector at the LHC) , the Large Hadron Collider’s (LHC’s) newest experiment [1]—which started official data taking in 2015—is totally different to other collider detectors.

    Institute of Particle Physics 2022-2026 Long Range Plan IPP Scientific Council1 17 November 2020 DRAFT for IPP Member Feedback 1Members of the elected IPP Scientific Council from June 2019 to May 2021: E.Caden (SNOLAB), K.Clark (Queen's), M.Hartz (TRI- UMF), B.Jamieson (Winnipeg), R.McPherson (Victoria/IPP), J.M. Roney (Chair, Victoria), B.Stelzer (SFU), D.Stolarski (Carleton), R.Tafirout (TRIUMF). Primary contact for this document is J.M. Roney, [email protected]. Executive Summary The members of the Institute of Particle Physics (IPP), through which Canadian particle physicists are self- organized, are addressing the most important and pressing fundamental scientific questions today. Through the IPP, Canada is having a disproportionately high impact on international particle physics projects and the goal of IPP during the period 2022-2026 is to maintain that leadership in the field. This brief documents how IPP plans to do that. • Big questions in Particle Physics The overarching goal of the IPP community is to continue to make significant progress on answering the \Big Questions" of our time: { Is there new physics at or above the TeV scale accessible to the LHC direct searches and precision measurements or rare decays from multiple experiments? { What is the nature of the dark matter (DM) that comprises 85% of matter in the universe? { Is there a hidden \dark sector" ? { What is the origin and nature of the matter-antimatter asymmetry that produced our matter-dominated universe? { What is the nature of the neutrino and what can we learn by probing neutrino oscillations? { How are gravity and dark energy incorporated into the rest of the particle physics theoretical framework, and how can that knowledge be used to understand the history of the universe? In tackling these questions IPP members train the next generation of scientists in multiple, high-level skills at the cutting edge of science, technology and problem solving in a competitive international environment.
