Pion decay in magnetic fields


  • Dr. Gergely ENDRODI

Primary authors


The leptonic decay of the charged pion in the presence of background magnetic fields is investigated using Wilson fermions. It is demonstrated that the magnetic field opens up a new channel for this decay. The magnetic field-dependence of the decay constants for both the ordinary and the new channel is determined. Using these inputs from QCD, we calculate the total decay rate perturbatively.
