Search for new light vector boson using at BESIII and Belle II

Kayoung Ban, Yongsoo Jho, Youngjoon Kwon +3

We investigate various search strategies for light vector boson in mass range using associated channels at BESIII and Belle II: (i) $J/Ψ\to η_…

Tribaryons in a constituent quark model

Aaron Park, Su Houng Lee

We calculate the matrix elements of the color-spin interaction for all possible multi-quark states of tribaryons in flavor SU(3) broken case. For that purpose, we construct the fla…

Stellar cooling, inelastic dark matter, and XENON

Wai-Yee Keung, Danny Marfatia, Po-Yan Tseng

We consider a novel scenario of dark photon-mediated inelastic dark matter to explain the white dwarf cooling excess suggested by its luminosity function, and the excess in electro…

Search for sterile neutrino with light gauge interactions: recasting collider, beam-dump, and neutrino telescope searches

Yongsoo Jho, Jongkuk Kim, Pyungwon Ko +1

We investigate features of the sterile neutrinos in the presence of a light gauge boson that couples to the neutrino sector. The novel bounds on the active-sterile neutrino m…

Exploring CP-violation, via heavy neutrino oscillations, in rare B meson decays at Belle II

Gorazd Cvetic, C. S. Kim, Sebastian Mendizabal +1

In this article we study the rare B-meson decay via two on-shell almost-degenerate Majorana Heavy Neutrinos, into two charged leptons and two pseudoscalar mesons ($B^{\pm} \to D^0…

Leptonic New Force and Cosmic-ray Boosted Dark Matter for the XENON1T Excess

Yongsoo Jho, Jong-Chul Park, Seong Chan Park +1

The recently reported excess in XENON1T is explained by new leptonic forces, which are free from gauge anomalies. We focus on two scenarios with and without dark matter. In Scenari…

Gravitational wave signals of dark matter freeze-out

Danny Marfatia, Po-Yan Tseng

We study the stochastic background of gravitational waves which accompany the sudden freeze-out of dark matter triggered by a cosmological first order phase transition that endows…

Probing new physics scenarios of muon via decay at BESIII

Gorazd Cvetič, C. S. Kim, Donghun Lee +1

The disagreement between the standard model prediction and the experimental measurement of muon anomalous magnetic moment can be alleviated by invoking an additional particle which…

D meson mass and heavy quark potential at finite temperature

Philipp Gubler, Taesoo Song, Su Houng Lee

Based on the observation that the heavy quark-antiquark potential value at infinity corresponds to twice the D meson mass, we constrain the asymptotic value of the heavy quark pote…

Beyond the Starobinsky model for inflation

Dhong Yeon Cheong, Hyun Min Lee, Seong Chan Park

We single out the Starobinsky model and its extensions among generic gravity as attractors at large field values for chaotic inflation. Treating a curvature term as a…

Heating neutron stars with GeV dark matter

Wai-Yee Keung, Danny Marfatia, Po-Yan Tseng

An old neutron star (NS) may capture halo dark matter (DM) and get heated up by the deposited kinetic energy, thus behaving like a thermal DM detector with sensitivity to a wide ra…

Light gauge boson interpretation for and the anomaly at the J-PARC KOTO experiment

Yongsoo Jho, Sung Mook Lee, Seong Chan Park +2

We discuss a list of possible light gauge boson interpretations for the long-standing experimental anomaly in and also recent anomalous excess in $K_L \rightarrow π^0 + \…

Vector-like Quark Interpretation for the CKM Unitarity Violation, Excess in Higgs Signal Strength, and Bottom Quark Forward-Backward Asymmetry

Kingman Cheung, Wai-Yee Keung, Chih-Ting Lu +1

Due to a recent more precise evaluation of and , the unitarity condition of the first row in the Cabibbo-Kobayashi-Maskawa (CKM) matrix: $|V_{ud}|^2 + |V_{us}|^2 +…
