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…
Open Horizons: Evaluating Deep Models in the Wild
Ayush Vaibhav Bhatti, Deniz Karakay, Debottama Das +2
Open-world deployment requires models to recognize both known categories and remain reliable when novel classes appear. We present a unified experimental study spanning open-set re…
Radiative corrections to the direct detection of the Higgsino-(and Wino-)like neutralino dark matter: Spin-dependent interactions
Subhadip Bisal, Arindam Chatterjee, Debottam Das +1
The lightest neutralino () is a promising dark matter (DM) candidate in the R-parity conserving minimal supersymmetric standard model (MSSM). In this work, we focus o…
Electroweak renormalization of neutralino-Higgs interactions at one-loop and its impacts on spin-independent direct detection of Wino-like dark matter
Subhadip Bisal, Arindam Chatterjee, Debottam Das +1
A Wino-like neutralino dark matter (DM) in the form of the lightest supersymmetric particle (LSP) has been considered one of the popular paradigms that can naturally accommodate {\…
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…
