Dark Matter and XENON1T Excess from Extended Standard Model

Nobuchika Okada, Satomi Okada, Digesh Raut +1

A gauged symmetry appended to the Standard Model (SM) is particularly well-motivated since it can account for the light neutrino masses by the seesaw mechanism, explain th…

SMART U(1) Standard Model with Axion, Right handed neutrinos, Two Higgs doublets and U(1) gauge symmetry

Nobuchika Okada, Digesh Raut, Qaisar Shafi

To address five fundamental shortcomings of the Standard Model (SM) of particle physics and cosmology, we propose a SMART U(1) model which is a extens…

Pseudo-Goldstone Dark Matter in gauged extended Standard Model

Nobuchika Okada, Digesh Raut, Qaisar Shafi

Gauging the global (Baryon number minus Lepton number) symmetry in the Standard Model (SM) is well-motivated since anomaly cancellations require the introduction of three rig…

Displaced Vertex and Disappearing Track Signatures in type-III Seesaw

Sudip Jana, Nobuchika Okada, Digesh Raut

We investigate a prospect of probing the type-III seesaw neutrino mass generation mechanism at various collider experiments by searching for a disappearing track and a displaced ve…

Inflection-Point Inflation with Axion Dark Matter in light of Trans-Planckian Censorship Conjecture

Nobuchika Okada, Digesh Raut, Qaisar Shafi

Motivated by the recently proposed Trans-Planckian Censorship Conjecture (TCC), we propose a gauged model of inflection-point inflation with axion dark matter. The Hubble sca…

Hunting Inflaton at FASER

Nobuchika Okada, Digesh Raut

We explore a possibility that an inflaton, which drives the cosmological inflation in the early Universe, can be detected by the recently approved FASER at the High-Luminosity LHC…
