Research


Prof. Krishna Kumar is an experimental particle/nuclear physicist. His current research focuses on precision measurements of weak neutral current interactions using fixed-target parity-violating electron scattering, and searches for neutrinoless double-beta decay.

  • Are there (as yet undetected) super-weak forces at sub-attometer length scales that shaped the evolution of the early universe?
  • Do neutrons in a heavy nucleus occupy a slightly larger volume than the protons, thus forming a "neutron skin"?
  • Are neutrinos their own anti-particles?
  • Is lepton number conserved?
  • Can quarks, gluons, their motion and self-interactions account for the observed properties of the proton?

Research Topics:

Parity-Violating Electron Scattering Experiments

Search for Neutrino-less Double Beta Decay
