Department of Physics, Presidency University organizes weekly lectures by eminent scientists across the globe where they talk about latest and cutting edge research and ideas. As a unique academic event in the country, this sets the stage for interaction with researchers from a diverse background in Physics and even outside of it. The lectures are supposed to be held on each Wednesday generally in the afternoon depending on the availability of the speakers.
Exploring boosted dark matter scenarios using IceCube

IceCube is the largest present neutrino detector at about 1 km^3 in instrumented volume. Built at the south pole, and deep into the Antarctic ice-bed, it is designed to detect ultra-high
energy neutrinos incident at the earth with energies of 1 TeV and above. Since being built in 2010, IC has had remarkable success, detecting more than a 5 sigma evidence of a neutrino
flux over and above known sources of neutrinos, such as those from cosmic ray interactions with atmospheric nuclei. In this talk, I will briefly describe the IceCube detector, its goals
and results, and the standard interpretations of said results. I will then discuss how this neutrino detector can be used to detect an altogether different kind of particle, namely fast
moving or "boosted" dark matter, showing in the process, that present observations at IC are really also compatible with this alternative scenario, for reasonable values of parameters
in the theory.
