## Main Question or Discussion Point

Can someone explain in easy to understand terms, what parity violation is? specifically:

"Only the left-handed components of particles and right-handed components of antiparticles participate in weak interactions in the standard model."

Thanks in advance.

BONUS: if you're like a particle physicist or something, could you also explain:

"A spin-1 exchange particle can be described by a vector (V) or axial vector (A) operator. Both would conserve parity, but if the operator is mixed, parity can be violated. The observation of maximal parity violation and purely left-handed neutrinos requires equal contributions of vector and axial vector with opposite sign (V-minus-A theory)."
