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…
Anomalies in String-inspired Non-local Extensions of QED
Fayez Abu-Ajamieh, Pratik Chattopadhyay, Anish Ghoshal +1
We investigate anomalies in the class of non-local field theories that have been proposed as an ultraviolet completion of 4-D Quantum Field Theory (QFT) with generalizing the kinet…
Experimentally distinguishable origin for electroweak symmetry breaking
Victor Baules, Nobuchika Okada
We consider a classically conformal gauge extension of the Standard Model (SM), in which the gauge symmetry is radiatively broken by the Coleman-Weinberg mechanism. T…
Split supersymmetry and hybrid inflation in light of Atacama Cosmology Telescope DR6 data
Nobuchika Okada, Qaisar Shafi
Inspired by the recent measurement of the scalar spectral index, , by the Atacama Cosmology Telescope (ACT) DR6 data, we present an update on the split sup…
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…
Testing neutrino mass hierarchy under type-II seesaw scenario in from colliders
Arindam Das, Puja Das, Nobuchika Okada
The origin of tiny neutrino mass is a long standing unsolved puzzle of the Standard Model (SM), which allows us to consider scenarios beyond the Standard Model (BSM) in a variety o…
