Report of Contributions CIPANP 2018 - Thirteenth Conference on the Intersections of Particle and Nuclear Physics Report of Contributions https://conferences.lbl.gov/e/137 CIPANP 2018 - T … / Report of Contributions Opening Contribution ID: 0 Type: Plenary Opening Tuesday, 29 May 2018 08:00 (5 minutes) I will welcome the participants of CIPANP 2018 and briefly review the history of this meeting that strives to strengthen the connections between nuclear, particle, and astro physicists. E-mail [email protected] Primary author: Prof. HAXTON, Wick (UC Berkeley and LBNL) Presenter: Prof. HAXTON, Wick (UC Berkeley and LBNL) Session Classification: Plenary 1 Track Classification: CPDE September 23, 2021 Page 1 CIPANP 2018 - T … / Report of Contributions Hadronic Contributions to Muon g- … Contribution ID: 1 Type: Parallel Hadronic Contributions to Muon g-2 and Spin Structure Functions Wednesday, 30 May 2018 14:20 (20 minutes) I will discuss the relation, viz. Schwinger’s sum rule, between the g-2 and the spin structure functions. It allows one to assess the hadronic (as well as other) contributions to muon g-2 by measuring the structure function. The latter can be accessed experimentally in inelastic muon- electron scattering. I will outline the prospects of such measurements at the muon-beam facilities. This presentation is based on: F. Hagelstein and V. Pascalutsa, Phys.Rev.Lett. 120 (2018) no.7, 072002 [DOI: 10.1103/PhysRevLett.120.072002] E-mail [email protected] Primary author: Dr PASCALUTSA, Vladimir (University of Mainz) Co-author: Dr HAGELSTEIIN, Franziska (University of Bern) Presenter: Dr PASCALUTSA, Vladimir (University of Mainz) Session Classification: Precision Physics at High Intensities Track Classification: PPHI September 23, 2021 Page 2 CIPANP 2018 - T … / Report of Contributions Large-Nc HPNC Analyses Post N … Contribution ID: 2 Type: Parallel Large-Nc HPNC Analyses Post NPDGamma Saturday, 2 June 2018 17:10 (20 minutes) It has long been appreciated that low-energy weak parity non-conserving interactions between nucleons are governed by five S-P amplitudes, as originally described by Danilov. The formalism can also be recast in pionless effective field theory, where the low-energy constants (LECs) arethe coefficients of the Danilov amplitudes. Lacking five high-quality independent constraints onthese LECs, many past analyses have relied on meson exchange theory for some guidance as to which of the five amplitudes might be dominant. This approach has had mixed success in correlating the data, particularly as no experimental evidence has so far emerged for a nonzero weak pion- nucleon-nucleon coupling. Recently a new hierarchy for the LECs has emerged from large Nc QCD. I describe a recent analysis based on this approach, one that appears to describe existing data quite well, while altering the relationships among past and anticipated experiments. I discuss how NPDGamma, other new experiments, and a future lattice QCD calculation of the isotensor Danilov amplitude will further advance the field.

At present, the main limitation in precision of this determination is due to radiative corrections, more specifically the “inner” γW -box correction that is independent of the electron spectrum but depends on hadronic structure. A novel dispersion formulation of the γW -box is developed. It allows to test the validity and improve the previous evaluation of Marciano and Sirlin, which was based on several semi-empiric assumptions. Further effects, such as possible effects of the nuclear excitations both on inner and outer corrections are discussed.

I focus on how the needs for accuracy and precision in current and future programs at high-energy accelerators are addressed in contemporary PDF sets. I discuss the impact on PDFs of the uncertainties coming from the data, the theory and the methodology, and I outline some corresponding challenges in their assessment.

Currently, there are experiments be- ing proposed which use decay-at-rest from kaons, pions, muons, and isotopes. I will present an overview of the decay-at-rest process, and the experiments being developed. After looking at the bigger picture, I will focus on particle accelerator driven decay-at-rest and the technology neces- sary to achieve the experimental goals (e.g. discovering sterile neutrinos).

These amplitudes serve as important input to constrain the hadronic piece of light-by-light scattering contribution to (g-2) and support the current experimental program at BESIII.

It provides an ideal setting for dark photon and dark Higgs search in a parameter space of great interest. In this energy, through kinetic mixing, the postulated low-mass (∼< 10 GeV) dark photon (and/or dark Higgs) particles could be produced in the Drell-Yan like q +q ¯ (or g + g) fusion processes in high energy proton + nucleus collisions, mostly in the beam dump (p + F e) and decay into dimuons (or di-electrons). For this search, a dedicated displaced-vertex trigger de- tector was built, installed and commissioned with upgraded DAQ in 2017. This trigger uses two planes of extruded scintillators to identify dimuons originating far downstream of the target, and is sensitive to dark photons (dark Higgs) that travel deep inside the beam dump before decaying to dimuons. We successfully took one week worth of production data parasitically with the E906 experiment in 2017. We will continue taking additional data parasitically alongside the upcoming SeaQuest polarized proton target physics program (E1039) for several years. In this talk wewill present the latest status of the preliminary dark photon search from 2017 data and also discuss future opportunity. E-mail [email protected] Collaboration

  • Possibilities for Underground Physics in the Pyh\" Asalmi Mine
    CIPANP2018-Trzaska-374 October 3, 2018 Possibilities for Underground Physics in the Pyhasalmi mine W.H. Trzaska1, L. Bezrukov2, T. Enqvist1, J. Joutsenvaara3, P. Kuusiniemi1, K. Loo1, B. Lubsandorzhiev2, V. Sinev2, M. Slupecki1 1Department of Physics, University of Jyvaskyla, Finland 2Institute for Nuclear Research, Russian Academy of Sciences, Moscow, Russia 3Kerttu Saalasti Institute, University of Oulu, Finland The Pyhasalmi mine is uniquely suited to host new generation of large- scale underground experiments. It was chosen both by the LAGUNA- LBNO and by the LENA Collaboration as the preferred site for a giant neutrino observatory. Regrettably, none of these projects got funded. The termination of the underground excavations in the fall of 2019 marks an important milestone. To maintain the infrastructure in good condi- tion a new sponsor must be found: either a large-scale scientific project or a new commercial operation. The considered alternatives for the commer- cial use of the mine include a pumped-storage hydroelectricity plant and a high-security underground data-storage centre. Without a new sponsor the ongoing experiments, including the cosmic-ray experiment EMMA and the study of C14 content in liquid scintillators, have to be completed within the next few years.

  • Acoustic Detection of Neutrinos in Bedrock
    EPJ Web of Conferences 216, 04009 (2019) https://doi.org/10.1051/epjconf/201921604009 ARENA 2018 Acoustic detection of neutrinos in bedrock Wladyslaw Henryk Trzaska1,, Kai Loo1, Timo Enqvist1, Jari Joutsenvaara2, Pasi Kuusiniemi1, and Maciej Slupecki1 1Department of Physics, University of Jyväskylä, Finland 2Kerttu Saalasti Institute, University of Oulu, Finland Abstract. We propose to utilize bedrock as a medium for acoustic detection of particle showers following interactions of ultra-high energy neutrinos. With the density of rock three-times larger and the speed of sound four-times larger compared to water, the ampli- tude of the generated bipolar pressure pulse in rock should be larger by an order of mag- nitude. Our preliminary simulations confirm that prediction. Higher density of rock also guarantees higher interaction rate for neutrinos. A noticeably longer attenuation length in rock reduces signal dissipation. The Pyhäsalmi mine has a unique infrastructure and rock conditions to test this idea and, if successful, extend it to a full-size experiment. 1 Introduction The pioneering 1957 paper by G.A. Askariyan [1] has outlined a mechanism converting energy de- posited by an ionising particle stopping in a liquid into a hydrodynamic pressure-wave. One of the widely investigated applications of this phenomenon is the search for the characteristic bipolar pres- sure pulses (BIP; see Fig. (1)) induced by cascades following interaction of ultra-high energy neutri- nos (E 1018 eV) with water or ice. These two target materials are the only ones currently used or ≥ intended for the future deployment of acoustic sensors. At some point salt domes and sub-arctic per- mafrost were also discussed as a possible detection material, but no large-scale measurements were attempted.

The nature of the anomalies remains unclear, but, in principle, they may be a signature of self-annihilation of a Weakly Interacting Massive Particle (WIMP) with a mass around 10 GeV/c2.

Abstract: This paper reviews the main experimental techniques and the most significant results in the searches for the 2e, eb+ and 2b+ decay modes. Efforts related to the study of these decay modes are important, since they can potentially offer complementary information with respect to the cases of 2b− decays, which allow a better constraint of models for the nuclear structure calculations.

    Simulation environment for the C14 experiment Pro Gradu, 23.12.2016 Author: Roope Sarala Supervisors: Timo Enqvist,Kai Loo 2 TIIVISTELMÄ Suuria tuikeaineilmaisimia käytetään erityisesti neutriinofysiikan kokeissa, joissa tutki- taan muun muassa aurinkoneutriinoja, neutriinotonta kaksinkertaista beetahajoamista sekä pimeää ainetta. Näissä kokeissa mitattava signaali on hyvin heikko, minkä vuoksi häiriöiden minimoiminen on hyvin tärkeää. Yksi suurimmista häiriötekijöistä on tuikeaineen sisältämä radiohiili, jonka taustasäteily käytännössä estää signaalin havaitsemisen noin 200 keV:iin saakka. Radiohiili (14C) on hiilen luonnossa esiintyvä beeta-aktiivinen isotooppi, jonka puo- liintumisaika on noin 5730 vuotta. Sitä syntyy pääasiassa kosmisen säteilyn osuessa yläilmakehän typpiatomeihin, jonka seurauksena radiohiiltä on kaikessa orgaanisessa aineessa vähäisiä määriä. Tuoreessa aineessa radiohiilipitoisuus on noin 10−12. Suu- ren mittaluokan kokeissa käytetyt tuikeaineet ovat usein jalostettu raakaöljystä. Iän perusteella öljyn radiohiilipitoisuus olisi luokkaa 10−21, mutta todellisuudessa se on lähempänä arvoa 10−17, sillä öljyyn muodostuu lisää radiohiiltä sitä ympäröivän kiven säteilyn vaikutuksesta. Radiohiilen aiheuttaman taustan vähentäminen hyödyttäisi siis kaikkia tulevia neutrii- nokokeita merkittävästi. Tätä tarkoitusta varten on rakennettu C14-konsentraatiomit- tauslaitteisto Pyhäsalmen kaivokselle CallioLab-tutkimuskeskukseen tutkimaan eri öljylähteistä valmistettuja tuikeaineita.
