Disc-Based Estimation of the Local Dark Matter Density and Velocity Distribution in IllustrisTNG50
Hatsume Chujo, Shogo Masaki, Keiko I. Nagao +1
We study the dark matter (DM) density and velocity distribution in the solar neighborhood of Milky Way-like galaxies using the TNG50-1 run of the IllustrisTNG simulation suite. Mil…
Neutrino Mass Model and Dark Matter with Inert Triplet Scalar
Shilpa Jangid, Keiko I. Nagao, Hiroshi Okada
We study a one-loop induced neutrino mass model with an inert isospin triplet scalar field of and heavier isospin doublet vector-like leptons and singlet Majorana right-hande…
Directional direct detection of light dark matter up-scattered by cosmic rays from direction of the Galactic center
Keiko I. Nagao, Satoshi Higashino, Tatsuhiro Naka +1
Dark matter with MeV scale mass is difficult to detect with standard direct search detectors. However, they can be searched for by considering the up-scattering of kinetic energies…
An alternative gauged symmetric model in light of the CDF II boson mass anomaly
Keiko I. Nagao, Takaaki Nomura, Hiroshi Okada
We consider an explanation of CDF II W bosom mass anomaly by mixing with gauge symmetry under which right-handed fermions are charged. It is found that is…
A model explaining the new CDF II W boson mass linking to muon and dark matter
Keiko I. Nagao, Takaaki Nomura, Hiroshi Okada
We propose a model to explain the W boson mass anomaly reported by the CDFII collaboration that would suggest new physics (NP). We introduce exotic fermions; one isospin doublet ve…
Modular symmetry and light dark matter with gauged
Keiko I. Nagao, Hiroshi Okada
We propose a radiative seesaw model with a light dark matter candidate (DM) under modular and gauged symmetries, in which neutrino masses are generated via one-l…
