Freeze-In Dark Matter from a Minimal B-L Model and Possible Grand
PHYSICAL REVIEW D 101, 115022 (2020) Freeze-in dark matter from a minimal B − L model and possible grand unification Rabindra N. Mohapatra1 and Nobuchika Okada 2 1Maryland Center for Fundamental Physics and Department of Physics, University of Maryland, College Park, Maryland 20742, USA 2Department of Physics and Astronomy, University of Alabama, Tuscaloosa, Alabama 35487, USA (Received 5 May 2020; accepted 5 June 2020; published 17 June 2020) We show that a minimal local B − L symmetry extension of the standard model can provide a unified description of both neutrino mass and dark matter. In our model, B − L breaking is responsible for neutrino masses via the seesaw mechanism, whereas the real part of the B − L breaking Higgs field (called σ here) plays the role of a freeze-in dark matter candidate for a wide parameter range. Since the σ particle is unstable, for it to qualify as dark matter, its lifetime must be longer than 1025 seconds implying that the B − L gauge coupling must be very small. This in turn implies that the dark matter relic density must arise from the freeze-in mechanism. The dark matter lifetime bound combined with dark matter relic density gives a lower bound on the B − L gauge boson mass in terms of the dark matter mass. We point out parameter domains where the dark matter mass can be both in the keV to MeV range as well as in the PeV range. We discuss ways to test some parameter ranges of this scenario in collider experiments. Finally, we show that if instead of B − L, we consider the extra Uð1Þ generator to be −4I3R þ 3ðB − LÞ, the basic phenomenology remains unaltered and for certain gauge coupling ranges, the model can be embedded into a five-dimensional SOð10Þ grand unified theory. -

The state financing has reached the lowest-ever level. The sudden drop in this financing was like pulling a pillow from under a dying. Many a weaker man dies, many a weaker institution perishes. This Annual Report bears witness that we have managed to survive, though we did not emerge quite unscathed: our personnel had decreased in number by about 15 %, the number of our publications did not increase (about 200), no discovery worth the Nobel prize was announced, etc. -

FASER: Forward Search Experiment at the LHC
Input to the European Particle Physics Strategy Update 2018-2020 Submitted 18 December 2018 FASER FASER: ForwArd Search ExpeRiment at the LHC FASER Collaboration Akitaka Ariga, Tomoko Ariga, Jamie Boyd,∗ Franck Cadoux, David W. Casper, Yannick Favre, Jonathan L. Feng,y Didier Ferrere, Iftah Galon, Sergio Gonzalez-Sevilla, Shih-Chieh Hsu, Giuseppe Iacobucci, Enrique Kajomovitz, Felix Kling, Susanne Kuehn, Lorne Levinson, Hidetoshi Otono, Brian Petersen, Osamu Sato, Matthias Schott, Anna Sfyrla, Jordan Smolinsky, Aaron M. Soffa, Yosuke Takubo, Eric Torrence, Sebastian Trojanowski, and Gang Zhang Abstract FASER, the ForwArd Search ExpeRiment, is a proposed experiment dedicated to searching for light, extremely weakly-interacting particles at the LHC. Such particles may be produced in the LHC's high-energy collisions in large numbers in the far-forward region and then travel long distances through concrete and rock without interacting. They may then decay to visible particles in FASER, which is placed 480 m downstream of the ATLAS interaction point. In this work, we describe the FASER program. In its first stage, FASER is an extremely compact and inexpensive detector, sensitive to decays in a cylindrical region of radius R = 10 cm and length L = 1:5 m. FASER is planned to be constructed and installed in Long Shutdown 2 and will collect data during Run 3 of the 14 TeV LHC from 2021-23. If FASER is successful, FASER 2, a much larger successor with roughly R ∼ 1 m and L ∼ 5 m, could be constructed in Long Shutdown 3 and collect data during the HL-LHC era from 2026-35. -

ECFA Newsletter #6
ECFA Newsletter #6 Following the Plenary ECFA meeting, 19 and 20 November 2020 https://indico.cern.ch/event/966397/ Winter 2020 It was a great pleasure for ECFA to endorse the membership of the ECFA Early-Career Research Panel at its meeting on 19 November 2020. The panel, made up mainly of PhD students and postdocs, will discuss all aspects that contribute in a broad sense to the future of the research field of particle physics. To capture what is on their minds and to estaBlish a dialogue with ECFA members, a delegation of early-career researchers will Be invited to Plenary and Restricted ECFA, while the panel will also advise and inform ECFA through regular reports. During the Plenary ECFA meeting, we heard about the progress in developing the Accelerator and Detector R&D Roadmaps. The European Strategy for Particle Physics (ESPP) calls on ECFA to develop a detector R&D roadmap to support proposals at European and national levels, and to achieve the ESPP objectives in a timely manner. The ECFA roadmap panel will develop the roadmap taking into consideration the targeted R&D projects required, as well as transformational Blue-sky R&D relevant to the ESPP. Open symposia, in March or April 2021, are part of the consultation with the community. In parallel, with a view to stepping up accelerator R&D, the European Laboratory Directors Group (LDG) is developing an accelerator R&D roadmap that takes into account a variety of technologies for further development during this decade. The roadmap will set the course for R&D and technology demonstrators to enaBle the development of future facilities that support the scientific objectives of the ESPP. -

Extending the Reach of FASER, MATHUSLA, and Ship Towards Smaller Lifetimes Using Secondary Particle Production
PHYSICAL REVIEW D 101, 095020 (2020) Extending the reach of FASER, MATHUSLA, and SHiP towards smaller lifetimes using secondary particle production Krzysztof Jodłowski * National Centre for Nuclear Research, Pasteura 7, 02-093 Warsaw, Poland † Felix Kling SLAC National Accelerator Laboratory, 2575 Sand Hill Road, Menlo Park, California 94025, USA ‡ Leszek Roszkowski Astrocent, Nicolaus Copernicus Astronomical Center of the Polish Academy of Sciences, ul.

This approach is, however, limited to new particles with decay lengths similar to or larger than the baseline of those experiments. In this study, we discuss how this basic constraint can be overcome in non-minimal beyond standard model scenarios. If more than one light new particle is present in the model, an additional secondary production of LLPs may take place right in front of the detector, opening this way a new lifetime regime to be probed. We illustrate the prospects of such searches in the future experiments FASER, MATHUSLA, and SHiP, for representative models, emphasizing possible connections to dark matter or an anomalous magnetic moment of muon.
