Unveiling the Vanishing Higgsino-Nucleon Scattering in the MSSM at Next-to-Leading Order
Subhadip Bisal, Arindam Chatterjee, Debottam Das +2
Higgsino dark matter (DM) is considered one of the most well-motivated and minimal DM scenarios arising from supersymmetric extensions of the Standard Model. Motivated by the requi…
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…
Implications of Sgr A on the -rays searches of Bino Dark Matter with
Utpal Chattopadhyay, Debottam Das, Sujoy Poddar +2
We analyse the impact of dark matter density spike around the Milky Way's supermassive black hole (SMBH), Sgr A, in probing the Bino-dominated neutralino dark matter (DM) $\til…
