Gsymmetry
Gsymmetry refers to a specific type of symmetry operation in quantum mechanics. It is a fundamental concept that describes how a physical system's properties remain unchanged under certain transformations related to its charge and parity. More precisely, Gsymmetry is the combination of charge conjugation (C) and parity inversion (P). Charge conjugation flips the sign of all charges in a system, effectively swapping particles with antiparticles. Parity inversion, on the other hand, inverts the spatial coordinates, reflecting the system through the origin.
The G-parity operator, denoted as G, is the product of the charge conjugation operator C and the
Gsymmetry is particularly important in particle physics, especially in the context of the strong nuclear force.
