2. Parity Violation in the Beta-Decay and the Helicity of the Neutrinos.
  • 2.1 Parity Violation in the Beta Decay of

60Co and the Helicity of the Neutrino.

Parity operation P:

transformation under parity operation
Transformation under Parity Operation
  • Invariant: t -> t; m -> m
  • Change in sign = parity violation:
