The combination of Charge
While a combined Charge, Parity, and Time (CPT
) transformation leaves a system invariant
some systems are not invariant under a combination
of just CP transformations. This was first proposed
by T.D. Lee
and C. N. Yang
in the 1950
and experimentally verified by C.S. Wu
a few years later.
Lee and Yang recieved the Nobel prize
for this work.
A charge transformation is when you take the charge of a particle and swap it's sign
e ---} -e
A parity transformation is when you change the sign of
the space coordinate of the particle
x ---} -x
A time transformation ,well go on guess.
