Radiative Corrections to the Direct Detection of Inelastic Scattering of Higgsino-like Neutralino Dark Matter
Arindam Chatterjee, Debottam Das, Syed Adil Pasha +2
The direct detection (DD) of Higgsino-like dark matter (DM) through inelastic scattering processes may provide a promising avenue, along with the elastic scattering, when the mass…
Sub-TeV Singlino Dark Matter in light from Sagittarius A and LUX-ZEPLIN Nuclear-Recoil Event
Utpal Chattopadhyay, Debottam Das, Rahul Puri +1
We investigate the impact of a dark matter density spike surrounding the Milky Way's supermassive black hole (SMBH) on the detectability of Singlino-dominated neutralino dark matte…
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…
