Charge conjugation parity

Webcharge conjugation, in particle physics, an operation that replaces particles with antiparticles (and vice versa) in equations describing subatomic particles. The name … Web13.3.3 Charge Conjugation The transformation of charge conjugation replaces all particles by their antiparticles without changing the position or the variables that describe the motion of the particle. In studying the effects of charge conjugation, we must distinguish between particles that have antiparticles and those that do not.

It is clear that in addition to P, also C is violated in the weak interac- WebAs this has precisely the form of the negative energy solution, it becomes clear that charge conjugation exchanges the particle and anti-particle solutions. Note that not only is the energy reversed, but the momentum is reversed as well. Spin-up is transmuted to spin-down. It can be shown that the parity is also flipped. c int shift https://veteranownedlocksmith.com

Since the gluon carries a colour charge, it is not an eigenstate of the C (charge conjugation) operator. 1) Why do I then find in the literature statements that the gluon carries charge parity -1? WebThe charge-conjugation, together with parity and time reversal operators, gives rise to one of the most profound discrete symmetry in nature.
