Prof. Ashutosh Kotwal's research focuses on the physics of fundamental particles and forces at high energies. The discovery of the Higgs boson has answered the 50-year old puzzle of how fundamental particles acquire mass. However, the properties of the Higgs boson are not understood, and neither is the process by which the Higgs field condenses everywhere in space. Prof. Kotwal is pursuing these questions experimentally using two approaches - precision measurements of fundamental parameters, and direct searches for new particles and forces.
