SN1987A Constraints of Light with Non-Mixing Polarisations
Debottam Das, Purusottam Ghosh, Rahul Puri
The observation of supernova 1987A (SN1987A) provides a unique opportunity to explore new physics beyond the Standard Model (BSM). The production of new particles in the supernova…

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…
