Description

The 2023 Chung-Ang University Beyond the Standard Model (CAU BSM) Workshop is the international meeting on Physics Beyond the Standard Model (Higgs, Dark Matter, Neutrino, Axion, Flavor, Inflation, Gravitational Waves) in Chung-Ang University, Korea. The aim of the BSM Workshop is to discuss interesting current topics and initiate the collaboration between experts and participants working on BSM physics in the globe. The third workshop will be held mostly in person, but remote participation on zoom will be also possible. We hope that the CAU workshop is to keep the community moving with lively discussion and participation.

The lecture room for the workshop is 310-B502, except on Wednesday. The Wednesday session will take place in 310-418.

        Detecting axions with chiral magnetic effects

        We show that dark matter axions or axion-like particles (ALP) induce spontaneously alternat- ing electric currents in conductors along the external magnetic fields due to the (medium) axial anomaly, realizing the chiral magnetic effects. We propose a new experiment to measure this cur- rent to detect the dark matter axions or ALP. These induced currents are the electron medium effects, directly proportional to the axion or ALP coupling to electrons, which depends on their microscopic physics, and also suppressed by the Fermi velocity. My talk is based on my paper, arXiv: https://arxiv.org/abs/2207.06884

        Gravitational Lensing in Gravitational Waves - Virtual

        Like electromagnetic waves propagating in the universe, gravitational waves (GWs) can be gravitationally lensed by massive objects between the distant source and the observer. Consequently, considering all known types of lensing configurations—governed by not only the relative position of the source to the lens but the size, shape, and distribution of the lens mass—is possible for the gravitational lensing of GWs. In this talk, I briefly introduce my several recent/ongoing works from searching microlensed GWs to parameter estimation of strongly lensed GWs.

        Primordial Cosmic complexity and effect of reheating

        We study the effect of reheating phase on the evolution of complexities in the primordial scalar fluctuations using the squeezed formalism. We study the evolution of the out-of-time correlator (OTOC) and the quantum discord starting from the inflationary epoch till the radiation-dominated epoch with different types of reheating phases. We find that, for a mode that re-enters the horizon after reheating, a finite reheating epoch clearly distinguishes the characteristic OTOC and quantum discord \textit{freeze-in} amplitude into three different classes that only depend on whether the equation of state parameter: $(i)$ $\wre=1/3$ $(ii)$ $\wre<1/3$, or, (iii) $\wre>1/3$ and not on particular reheating histories. Taking the central value of $n_s$ as and $\wre=0.25$ benchmark values, we found that the behavior of the complexities for all modes smaller than $1.27\times10^{16}\mathrm{Mpc^{-1}}$ can be classified as above. Conversely, for modes re-entering the horizon during reheating, the signature of EoS on the evolution of the complexities will be embedded in each separately.

        Halo-independent bounds on the non-relativistic effective theory of WIMP-nucleon scattering from direct detection and neutrino observations 310-B502

        310-B502

        Chung-Ang University

        Centennial Hall (310), Chung-Ang University, Seoul, Republic of Korea.

        In my presentation I will talk about the halo-independent bounds on the WIMP-nucleon couplings of the non-relativistic effective Hamiltonian that drives the scattering process off nuclei of a WIMP of spin 1/2. We will see that for most of the couplings the degree of relaxation of the halo-independent bounds compared to those obtained by assuming the Standard Halo Model is with few exceptions relatively moderate in the low and high WIMP mass regimes, where it can be as small as a factor of 2, while in the intermediate mass range (10 -- 200 GeV) it can be as large as 1000. An exception to this general pattern, with more moderate values of the bound relaxation, is observed in the case of the spin-dependent type WIMP-proton couplings with no or a comparatively small momentum suppression, for which WIMP capture in the Sun is strongly enhanced because it is driven by scattering events off Hydrogen, the most abundant target in the Sun. Within this class of operators the relaxation is particularly small for interactions that are driven by only the velocity-dependent term, for which the solar capture signal is enhanced because of the high speed of scattering WIMPs inside the strong gravitational field of the Sun.
