Diffuse Supernova Neutrinos with Secret Neutrino Interactions

Praveen Bharadwaj, Utpal Chattopadhyay, Dilip Kumar Ghosh +1

The Diffuse Supernova Neutrino Background (DSNB), an isotropic flux arising from the cumulative neutrino emission of all stellar core-collapse events throughout cosmic history, is…

Constraints on lepton flavor universal and non-universal New Physics in $b \to s ℓ^{+} ℓ^{-}$ decays: a global SMEFT survey

Md Isha Ali, Utpal Chattopadhyay, Dilip Kumar Ghosh +1

The flavor-changing neutral current semileptonic decays of $B$ mesons provide an excellent platform for indirectly probing New Physics (NP) beyond the Standard Model (SM). Recent m…
