Das Arindam

Dr. Das is interested in the phenomenological aspects of physics Beyond the Standard Model (BSM). Motivated by well-established observational evidence—including neutrino oscillations and flavor mixing, the relic abundance of dark matter (DM), and the baryon asymmetry of the universe—his work focuses on theoretical frameworks that extend the Standard Model (SM). In addition to these empirical motivations, the SM faces a significant theoretical challenge: the gauge hierarchy problem, which may be addressed within the context of TeV-scale BSM physics. Consequently, investigating physics beyond the Standard Model remains a key priority in both theoretical and experimental particle physics.

His research spans a broad range of BSM scenarios, with particular emphasis on model building for current and future experiments. These include beam-dump experiments (proton and electron-positron beam-dumps) and high-energy colliders such as the LHC and ILC. He also investigates the implications of these models in the context of astroparticle physics—exploring phenomena such as gamma-ray bursts, ultra-high-energy neutrinos from cosmic rays, and supernovae—as well as in multi-messenger astrophysics, including gravitational waves originating from first-order phase transitions and cosmic strings.

His overarching objective is to understand the role of BSM physics across the intensity (sub-TeV scale), energy (TeV scale), and cosmic (PeV scale) frontiers, thereby contributing to a unified and experimentally testable framework for fundamental interactions.
