The CPT group of the spin-3/2 field
We find out that both the matrix and the operator CPT groups of the spin-3/2
field (with or without mass) are respectively isomorphic to
and . These groups are exactly
the same groups as for the Dirac field, though there is no a priori reason why
they should coincide.Comment: 9 pages. We are replacing the original version (v1) because there was
a mistake in the calculation which led to wrong group
Charge Conjugation from Space-Time Inversion
We show that the CPT group of the Dirac field emerges naturally from the PT
and P (or T) subgroups of the Lorentz group.Comment: 4 pages, no figure
