Description

The Chung-Ang University Beyond the Standard Model (CAU BSM) Workshop is the first meeting on Physics Beyond the Standard Model (Higgs, Dark Matter, Axion, Inflation, GWs and Neutrino Physics) in Chung-Ang University, Korea. We aim at inviting experts on discussing interesting current topics and initiating the collaborations between different institutions in the globe. Although the first series starts with ZOOM on the web, the CAU workshop is to keep the community connected with lively discussion and participation.

  SU(2) Anomaly for DE Source
  
  I show a possibility that a quintessential axion (with its breaking by the weak SU(2) gauge anomaly) can be the source of dark energy. However, I cannot show why the minimum of the potential is at the zero value for the cosmological constant.

  Cooling of young neutron stars and dark gauge bosons
  
  The standard cooling scenario in the presence of nucleon superfluidity fits rather well to the observation of the neutron stars. It implies that the stellar cooling arguments could place a stringent constraint on the properties of novel particles. We study in particular the cooling rate induced by dark gauge bosons for very young neutron stars: remnants of Cassiopeia A and SN1987A. The cooling is dominantly contributed either by the nucleon pair breaking and formation in the core or by the electron bremsstrahlung in the crust, depending on the age of the stars and the form of the couplings. We compute how much the cooling curve of the young neutron stars could be modified by the extra dark gauge boson emission and obtain the bound for the dark gauge boson.

  Hunting for New Physics in Neutrino Oscillation Experiments
  
  The goal of this phenomenology-oriented talk is to highlight some of the
  manifold ways in which neutrino oscillation experiments contribute to
  the global search for physics beyond the Standard Model. We will in
  particular discuss searches for sterile neutrinos (for which there exist
  some tantalizing but controversial hints), searches for new interactions
  in an effective field theory context, and searches for dark matter.
  Moreover, we will highlight the tremendous potential of neutrino "Near
  Detectors" for probing light and weakly interacting new particles.
  Throughout the talk, we will also highlight the Standard Model
  challenges that current and future neutrino oscillation experiments are
  facing, in particular with regard to precision prediction for
  neutrino-nucleus interactions.

  Primordial Black Hole Domination: Dark Matter, Dark Radiation, and Gravitational Waves
  
  If even a relatively small number of primordial black holes (PBH) were created in the early universe, they will constitute an increasingly large fraction of the total energy density as space expands. It is thus well-motivated to consider scenarios in which the early universe was dominated by short lived PBH (M < 10^9 grams, t < 1 sec)
  whose Hawking radiation produces both the Standard Model radiation bath and other exotic gravitationally coupled species. Within this context, we consider Hawking radiation as a mechanism to produce dark radiation and dark matter. In a PBH dominated era, we find that Schwarzschild Hawking evaporation produces dark radiation at a level ΔNeff∼0.03−0.2 for each light and decoupled species of spin 0, 1/2, or 1. During this era, dark matter could also originate as Hawking radiation, although such dark matter candidates must be very heavy (m >10^11 GeV) to avoid overproduction. Furthermore, if the PBH undergo mergers before evaporating, the subsequent population acquires nonzero spin, so the resulting Kerr Hawking radiation efficiently produces gravitons whose contribution to ΔNeff is within the reach of future CMB experiments; such mergers also predict a characteristic spectrum of primordial gravitational waves at high frequencies correlated with the progenitor PBH mass.
