Description

This meeting revives the annual Berkeley Week events we used to have before the pandemic. It brings students and postdocs from Berkeley and the University of Tokyo together primarily in the area of particle phenomenology for exchanging ideas and mutual inspiration. It provides international experience for both sides. Even within the University of Tokyo, it provides a valuable opportunity for people from Department of Physics, Institute for Cosmic Ray Research (ICRR), Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU), Research Center for the Early Universe (RESCEU), and International Center for Elementary Particle Physics (ICEPP) to get together.

Due to various constraints, this is the first time to hold this meeting on Hongo Campus.

The cost for the reception is 3,000 yen each.

    Deciphering the Mysteries of the Long-Lived Particles: Perspectives from LHC, FCC-hh and Muon Collider 1h Room 913
    
    Room 913
    
    Conventional searches at the LHC operate under the assumption that Beyond the Standard Model particles undergo immediate decay upon production. However, this assumption lacks inherent a priori justification. This talk delves into the exploration of displaced decay signatures across various collider experiments. Combining insights from several studies, we show how small Yukawa couplings, compressed mass spectra, and collider boosts lead to distinctive displaced decays, observable at the CMS, ATLAS and proposed future detectors. These phenomena, manifesting within both Type-I and Type-III seesaw mechanisms, the Vector-like lepton model with non-zero hypercharge, and the Inert Triplet Model, provide a unique insight into the behaviors of neutrinos and dark matter. The seminar highlights the technical challenges and breakthroughs in detecting and interpreting these signatures, emphasizing their significance in probing the depths of the extensions of the Standard Model.
