SUMMARY

The discussion centers on the violation of parity in weak interactions, specifically addressing the concept of parity conservation, which was assumed to hold until 1956. It is established that weak interactions, characterized by a linear combination of vector (V) and axial vector (A), do not conserve parity, leading to what is termed "maximal violation." This occurs because the effective interaction term is represented as V-A, indicating equal contributions from both vectors rather than a minor contribution from A.

The "parity" operation is thre reflection of all thrre axes,
x-->-x, etc. Until 1956, the assumption was made that changes the axes in this way did not affect the result of any experiment. That was called "parity conservation".
Conservation of parity is violated in weak interactions because the basic weak interaction is a linear combination of a vector (V)and an
axial vector (A). (The EM interraction is pure vector and conserves parity.) The violation is said to be "maximal" because the effective interaction term is V-A, so that the V and A have equal effect, rather than having just a little A.
