Fermi-LAT GeV excess and muon in a modular symmetry
Jongkuk Kim, Hiroshi Okada
The recent measurement of muon anomalous magnetic dipole moment (muon ) suggests that there might exist new physics that dominantly interacts with muons. The observed gamma-ra…
Supernova Axion Emissivity with Resonance in Heavy Baryon Chiral Perturbation Theory
Shu-Yu Ho, Jongkuk Kim, Pyungwon Ko +1
In this paper, we evaluate the energy loss rate of supernovae induced by the axion emission process with the resonance in the heavy baryon chiral pert…
Natural mass hierarchy among three heavy Majorana neutrinos for resonant leptogenesis under modular symmetry
Dong Woo Kang, Jongkuk Kim, Takaaki Nomura +1
It is clear that matter is dominant in the Universe compared to antimatter. We call this problem baryon asymmetry. The baryon asymmetry is experimentally determined by both cosmic…
Compatibility of muon , mass anomaly in type-X 2HDM
Jongkuk Kim
Recently CDF II Collaboration reported that they measured W boson mass precisely. The measurement is deviated from the Standard Model (SM) Prediction at 7. Also, the recent FNAL…
Muon and Thermal WIMP DM in Models
Seungwon Baek, Jongkuk Kim, P. Ko
The model is anomaly-free with the Standard Model (SM) fermion content, and can make substantial contributions to the muon at the level of $Δa_μ\sim…
The Forward Physics Facility at the High-Luminosity LHC
Jonathan L. Feng, Felix Kling, Mary Hall Reno +233
High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing L…
Muon in Symmetric Gauged Radiative Neutrino Mass Model
Dong Woo Kang, Jongkuk Kim, Hiroshi Okada
We explore muon anomalous magnetic moment (muon ) in a scotogenic neutrino model with a gauged lepton number symmetry . In this model, a dominant muon contri…
Dispersion of neutrinos in a medium
Ki-Young Choi, Eung Jin Chun, Jongkuk Kim
We analyze the dispersion relations of Weyl or Majorana, and Dirac neutrinos in a complex scalar medium which interacts with the neutrinos through Yukawa couplings. They are solved…
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…
A radiative seesaw model linking to XENON1T anomaly
Jongkuk Kim, Takaaki Nomura, Hiroshi Okada
We propose an attractive model that excess of electron recoil events around 1-5 keV reported by the XENON1T collaboration nicely links to the tiny neutrino masses based on a radiat…
XENON1T excess in local DM models with light dark sector
Seungwon Baek, Jongkuk Kim, P. Ko
Recently XENON1T Collaboration announced that they observed some excess in the electron recoil energy around a 2-3 keV. We show that this excess can be interpreted as exothermic sc…
Neutrino Oscillations in Dark Matter
Ki-Young Choi, Eung Jin Chun, Jongkuk Kim
We study neutrino oscillations in a medium of dark matter which generalizes the standard matter effect. A general formula is derived to describe the effect of various mediums and t…
Electron EDM and Muon anomalous magnetic moment in Two-Higgs-Doublet Models
Eung Jin Chun, Jongkuk Kim, Tanmoy Mondal
The CP violating two-Higgs doublet model of type-X may enhance significantly the electric and magnetic moment of leptons through two-loop Barr-Zee diagrams. We analyze the general…
Constraining dark matter-neutrino interactions with IceCube-170922A
Ki-Young Choi, Jongkuk Kim, Carsten Rott
Astrophysical neutrinos travel long distances from their sources to the Earth traversing dark matter halos of clusters of galaxies and that of our own Milky Way. The interaction of…
Searching for Flavored Gauge Bosons
Eung Jin Chun, Arindam Das, Jinsu Kim +1
Standard Model may allow an extended gauge sector with anomaly-free flavored gauge symmetries, such as , , and , where are fla…
Thermal production of light Dirac right-handed sneutrino dark matter
Ki-Young Choi, Jongkuk Kim, Osamu Seto
We consider the production of right-handed (RH) sneutrino dark matter in a model of Dirac neutrino where neutrino Yukawa coupling constants are very small. Dark matter RH sneutrino…
Non-thermal WIMP baryogenesis
Ki-Young Choi, Sin Kyu Kang, Jongkuk Kim
We propose a WIMP baryogensis achieved by the annihilation of non-thermally produced WIMPs from decay of heavy particles, which can result in low reheating temerature. Dark matter…
Galactic center GeV gamma-ray excess from dark matter with gauged lepton numbers
Jongkuk Kim, Jong-Chul Park, Seong Chan Park
The recently observed excess in gamma-ray signal near the Galactic center suggests that dark matter particles may annihilate into charged fermions that produce gamma-ray to be obse…
