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…
Inflation, Proton Decay, and Higgs-Portal Dark Matter in
Nobuchika Okada, Digesh Raut, Qaisar Shafi
We propose a simple non-supersymmetric grand unified theory (GUT) based on the gauge group . The model includes 3 generations of fermions in ()…
Fermion Mass Hierarchy and Phenomenology in the 5D Domain Wall Standard Model
Nobuchika Okada, Digesh Raut, Desmond Villalba
We have recently proposed a setup of the "Domain-Wall Standard Model" in 5D spacetime, where all the Standard Model (SM) fields are localized in certain domains of the extra 5th di…
