Constraints on High-Frequency Gravitational Waves from Graviton-Photon Conversion in the M87 Galaxy
Aman Gupta, Pratik Majumdar, Sourov Roy +1
High-frequency gravitational waves, particularly in the range , represent a compelling probe of physics beyond the Standard Model. Due to the absence…
Probing mixed-state dark matter and flavor observables in a scalar-assisted baryonic gauge theory
Taramati, Manas Kumar Mohapatra, Utkarsh Patel +2
We explore a {standard model} extension based on a local symmetry, where a baryon-charged scalar mediates interactions between a fermionic dark matter candidate and {stand…
Radiative Dirac neutrino masses and dark matter in a extended model
Chayan Majumdar, Utkarsh Patel, Supriya Senapati +1
We study a extension of the Standard Model (SM) in which Dirac neutrino masses are generated radiatively at the one-loop level through the exchange of new beyond the S…
Enhancing the sensitivity to neutrino oscillation parameters using synergy between T2K, NOA and JUNO
Srubabati Goswami, Aman Gupta, Ushak Rahaman +1
We study the impact of combining the present NOA and T2K data with simulated data from the JUNO experiment on the determination of the leptonic CP phase and the neutrino mass hi…
Dark Secrets of Baryons: Illuminating Dark Matter-Baryon Interactions with JWST
Souradeep Das, Ranjini Mondol, Abhijeet Singh +1
The James Webb Space Telescope (JWST) has discovered bright galaxies at high redshifts () and various galaxy candidates extending to even higher redshifts ($z\appro…
Scalaron dark matter dynamics: effects of Higgs non-minimal coupling to gravity
Shibendu Gupta Choudhury, Koushik Dutta, Deep Ghosh
One of the key features of the -gravity is the embedding of a scalar field, scalaron, into the gravity sector. The scalaron interacts with the Standard Model (SM) matter field…
