Endothermic Z'-Portal Dark Matter: LZ-LHC Complementarity
Nobuchika Okada, Digesh Raut
Motivated by the high-energy recoil event recently reported by the LUX-ZEPLIN (LZ) Collaboration, we consider an endothermic -portal Majorana dark matter framework…
Nambu-Goldstone boson phenomenology in Domain-Wall Standard Model
Puja Das, Nobuchika Okada, Digesh Raut +1
We investigate the Domain-Wall Standard Model (DWSM), a five-dimensional framework in which all Standard Model (SM) particles are localized on a domain wall embedded in a non-compa…
Analytic formulation of Leptogenesis with neutrino oscillation data employing the general parametrization for neutrino mass matrix
Nobuchika Okada, Digesh Raut
The observed neutrino oscillations and baryon asymmetry, unexplained by the Standard Model (SM), can both be accounted for by extending the SM to include Majorana right-handed neut…
Double Inflation in Classically Conformal Model
Anish Ghoshal, Nobuchika Okada, Arnab Paul +1
It has recently been shown in Ref. [1] that the double-inflation scenario based on the Coleman-Weinberg potential can successfully generate primordial black holes (PBHs) with the i…
Higgs-Portal Dark Matter in Brane-World Cosmology
Taoli Liu, Nobuchika Okada, Digesh Raut
The Higgs-portal scalar dark matter (DM) model is a simple extension of the Standard Model (SM) to incorporate a DM particle to the SM, where a -odd real scalar field is intro…
Axions, WIMPs, proton decay and observable in
Nobuchika Okada, Digesh Raut, Qaisar Shafi
We explore some experimentally testable predictions of an axion model which includes two 10-plets of fermions in order to resolve the axion domain wall problem. The axion…
