Positronium Decays with Dark and Fermionic Dark Matter

Dong-Won Jung, Chaehyun Yu, Kang Young Lee

We investigate the invisible decay of positronium to probe the fermionic light dark matter mediated by the dark boson. Too tiny is the invisible decay rate of positronium throu…

Reheating in Models with Non-minimal Coupling in metric and Palatini formalisms

Dhong Yeon Cheong, Sung Mook Lee, Seong Chan Park

We study reheating of inflationary models with general non-minimal coupling with where is the Ricci scalar and is the inflaton potential. In…

CP violation in the rare Higgs decays via exchange of on-shell almost degenerate Majorana neutrinos, and

Gorazd Cvetič, C. S. Kim, Jiberto Zamora-Saá

We investigate rare decays of Higgs via exchange of two almost degenerate heavy on-shell Majorana neutrinos (): …

The masses of hadrons in the chiral symmetry restored vacuum

Jisu Kim, Su Houng Lee

We calculate the masses of the vector and axial-vector mesons as well as the nucleon and the delta resonance in the chiral symmetry restored vacuum. This is accomplished by separat…

The -Higgs inflation with two Higgs doublets

Sung Mook Lee, Tanmoy Modak, Kin-ya Oda +1

We study -Higgs inflation in a model with two Higgs doublets in which the Higgs sector of the Standard Model is extended by an additional Higgs doublet, thereby four scalar fi…

Correlated gravitational wave and microlensing signals of macroscopic dark matter

Danny Marfatia, Po-Yan Tseng

Fermion dark matter particles can aggregate to form extended dark matter structures via a first-order phase transition in which the particles get trapped in the false vacuum. We st…

Inferring the nature of active neutrinos: Dirac or Majorana?

C. S. Kim, M. V. N. Murthy, Dibyakrupa Sahoo

The nature of a neutrino, whether it is a Dirac type or Majorana type, may be comprehensively probed using their quantum statistical properties. If the neutrino is a Majorana fermi…

Case for quarkyoniclike matter from a constituent quark model

Aaron Park, Kie Sang Jeong, Su Houng Lee

Based on the fact that the constituent quark model reproduces the recent lattice result on baryon-baryon repulsion at short distance and that it includes the quark dynamics with co…

Axion-like particles, two-Higgs-doublet models, leptoquarks, and the electron and muon g-2

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

Data from the Muon g-2 experiment and measurements of the fine structure constant suggest that the anomalous magnetic moments of the muon and electron are at odds with standard mod…

A comprehensive study of vector leptoquark with on the -meson and Muon g-2 anomalies

Kayoung Ban, Yongsoo Jho, Youngjoon Kwon +3

Recently reported anomalies in various meson decays and also in the anomalous magnetic moment of muon motivate us to consider a particular extension of the standard m…

Progress in Higgs inflation

Dhong Yeon Cheong, Sung Mook Lee, Seong Chan Park

We review the recent progress in Higgs inflation focusing on Higgs- inflation, primordial black hole production and the term.

The Doubly-heavy Tetraquarks () in a Constituent Quark Model with a Complete Set of Harmonic Oscillator Bases

Sungsik Noh, Woosung Park, Su Houng Lee

We have improved our previous variational method based constituent quark model by introducing a complete set of 3-dimensional harmonic oscillator bases as the spatial part of the t…
