  1. 1. Hunting Axions Using Astrophysical Observation and Quantum Metrology
    Yifan Chen (ITP-CAS)
    03/11/2021, 11:00

    Ultralight bosons behave like coherent waves when the occupation number is large enough. If they are coupled to the Standard Model sector of the particle physics, such an oscillating background can induce a tiny signal. Near a fast rotating black hole, axion within one order of the mass window can accumulate through superradiance, with a large density saturating the non-linear...

  2. 2. Gegenbauer Goldstones
    Gauthier Durieux (CERN)
    17/11/2021, 11:00

    We investigate radiatively stable classes of pseudo-Nambu-Goldstone boson (pNGB) potentials for approximate spontaneously broken $\text{SO}(N+1)\to\text{SO}(N)$. Using both the one-loop effective action and symmetry, it is shown that a Gegenbauer polynomial potential is radiatively stable, being effectively an `eigenfunction' from a radiative perspective. In Gegenbauer pNGB models, one...

  3. 3. Expecting the Unexpected at the LHC and Beyond
    David Shih (Rutgers University)
    08/12/2021, 16:00

    Despite countless searches at the LHC, there is still no evidence for new physics. The overwhelming majority of these searches are highly model-specific, motivated by (and optimized for) top-down considerations such as SUSY, extra dimensions, etc. This leaves a vast phase space unexplored by current searches. Could it be that we're not looking in the right places? In recent years, there has...

  4. 6. Dark Matter from dark gauge theories
    Michele Redi (Universita e INFN, Firenze (IT))
    15/12/2021, 11:00

    In this talk I will describe dark sectors made of non-abelian gauge theories with fermions neutral under the Standard Model. This leads to accidentally stable Dark Matter candidates that can be populated minimally through gravitational interactions. In the pure glue scenario DM is the lightest glueball while adding light fermions the lightest pion and baryon are the DM candidates. Despite the...

  5. 7. Maximizing Direct Detection with HYPER Dark Matter
    Gilly Elor
    15/12/2021, 13:00

    Faced with null results in the direct search of WIMP dark matter, there is growing motivation to explore dark matter candidates too light to be directly detected at current experiments. Indeed, there exists a vast array of proposals for direct detection experiments sensitive to sub-GeV dark matter coupled to nucleons. But can dark matter with a consistent cosmological history populate the...

  6. 13. Cosmological Relaxation through the Dark Axion Portal
    Valerie Domcke (CERN)
    26/01/2022, 11:00

    The dark axion portal is a coupling of an axion-like particle to a dark photon kinetically mixed with the visible photon. I will demonstrate how this portal, when applied to the relaxion, can lead to cosmological relaxation of the weak scale using dark photon production. The key backreaction mechanism which triggers the trapping of the Higgs vev at the desired value involves the Schwinger...

  10. 19. The next-generation High Intensity Kaon Experiment (HIKE)
    Avital Dery (Cornell)
    06/04/2022, 11:00

    Kaon physics has played a tremendous role in the history of flavor physics and CP violation. In the past few decades, the B meson program has taken over as the main driving force for advancements in the field. I will discuss recent theoretical developments that have inspired a novel proposal for a next generation experiment for the detection of neutral kaon decays into charged particles. The...
