Parity

In physics, parity is a transformation in which the mirror image of a system (meaning experiment) is considered.  If the system behaves in the mirror image as it normally would, it is said to respect parity symmetry, usually shortened to "P symmetry."   Most types of physics respects P symmetry.  One type of interaction that often does not respect this symmetry is the weak interaction.
