Probing CP-violating Higgs-Gauge couplings with Higgsstrahlung at collider
Amir Subba, Subhaditya Bhattacharya, Abhik Sarkar
We investigate the sensitivity of a future high-luminosity collider operating at to CP-violating and CP-conserving anomalous interactions v…
Lepton Collider as a Window to Reheating via Freezing Out Dark Matter Detection
Subhaditya Bhattacharya, Anupam Ghosh, Niloy Mondal +1
We investigate a particle dark matter (DM) scenario where the DM interaction with the Standard Model are mediated by a leptophilic effective operator. Unlike conventional WIMP scen…
Optimal estimation of Higgs-Gauge Boson couplings at the future colliders
Subhaditya Bhattacharya, Amir Subba, Abhik Sarkar
The proposed collider offers an ideal environment for precise estimation of Higgs boson properties which are of utmost importance to validate the Standard Model of particl…
Lepton flavor violating top quark FCNC processes at the TRISTAN
Abhik Sarkar
We investigate charged lepton flavor violating top quark flavor-changing neutral current interactions at the proposed asymmetric muon-electron collision stage of the TRISTAN col…
Up-type FCNC in presence of Dark Matter
Subhaditya Bhattacharya, Lipika Kolay, Dipankar Pradhan +1
Dark Matter (DM) is a known unknown. Apart, current experimental constraints on flavor-changing neutral current (FCNC) processes involving up-type quarks also provide scope to expl…
Probing lepton number violating SMEFT operators at the same-sign muon collider
Subhaditya Bhattacharya, Soumyajit Datta, Abhik Sarkar
We investigate lepton number violation (LNV) induced by dimension-seven Standard Model Effective Field Theory (SMEFT) operators in the context of same-sign muon colliders.…
