About Me
I am Santosh Kumar Rai, a Professor at the Harish-Chandra Research Institute, specializing in Particle Physics Phenomenology. My research primarily focuses on Beyond Standard Model (BSM) physics and its implications for collider studies. I have explored various supersymmetric theories, including the Minimal Supersymmetric Standard Model (MSSM) and its extensions like the NMSSM and left-right supersymmetry, all of which present intriguing phenomenological signatures at experiments. My work also delves into extended gauge symmetries beyond the Standard Model, with implications for both neutrino physics and collider studies. In addition, I conduct research on Higgs physics, extending beyond minimal scalar sector models to investigate how these frameworks can impact new physics signals and the extraction of couplings to matter fields. My interests also encompass extra-dimensional models and their associated phenomenology. My primary focus is on analyzing BSM physics at current and proposed future colliders, including the LHC, ILC, CLIC, LHeC, and FCC.
