Introduction and Theoretical Background
... The masses of the quarks and leptons pose another problem. The weak interaction violates parity, coupling differently to left and right-handed quark and lepton helicity states. To account for this in the SM, the left and right-handed fermions are treated as different fields, with different couplings. A ...
