Current Research

Our group works on experimental high-energy physics at various accelerator laboratories around the world: KEK (Japan), IHEP (China) and CERN (Switzerland). We primarily study the weak interaction between quarks (flavour physics) making measurements related to matter-antimatter asymmetry in the decays of charm and beauty quarks. We also collaborate with Profs. Behera and Pujahari on the CMS experiment at CERN.
