Such a charge separation is a consequence of . Naive dimensional analysis predicts these forces to be dominated by long-range one-pion-exchange processes, with short-range forces entering only at next-to-next-to-leading order in the chiral expansion. Physically what is implied when parity is violated in beta decay, is that the bosons involved in the weak interaction (the interaction involved with Beta Decay) only interact with certain types of matter, and certain other types of anti-matter. Exquisitely precise (1%) measurements of atomic parity violation have been made in recent years. Nuclear Physics B, 1991. Nuclear physicists. The effect is caused by the mixing of opposite parity rotational states of a cold, strongly deformed nucleus. .
