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 decays: a global SMEFT survey
Md Isha Ali, Utpal Chattopadhyay, Dilip Kumar Ghosh +1
The flavor-changing neutral current semileptonic decays of mesons provide an excellent platform for indirectly probing New Physics (NP) beyond the Standard Model (SM). Recent m…
Constraining lepton flavor violating SMEFT operators from low-energy cLFV processes
Utpal Chattopadhyay, Debottam Das, Rahul Puri +1
Charged lepton flavour-violating (cLFV) processes, which are definite proof of new physics beyond the Standard Model, have remained elusive experimentally till now. Effective Field…
SMEFT analysis of charged lepton flavor violating -meson decays
Md Isha Ali, Utpal Chattopadhyay, N Rajeev +1
Charged lepton flavor violation (cLFV) processes, potentially important for various Beyond the Standard Model Physics scenarios are analyzed in the Standard Model Effective Field T…
