Wednesday lecture series

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


   Dr. Atri Bhattacharya

Space sciences, Technologies and Astrophysics Research (STAR) Institute, Université de Liège

    Wednesday, 28 December, 2 p.m., PLT 2


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.
