Professor Kirch’s research is centred on fundamental particle physics with ultra-cold neutrons and muons.

His group’s experiments are precision measurements at low particle energies and can be divided into two categories: high-precision measurements of fundamental parameters of the standard model and searches for processes forbidden in the standard model.

One example is the search for a permanent electric dipole moment (EDM) of the neutron, which would violate time reversal invariance and could have something to do with the asymmetry between matter and antimatter in the universe.
