Hi,
I have a conceptual problem in understanding the SUSY (N=1) massless supermultiplet.
Using appropriately normalized creation and annihilation operators Q, Q+ (only one component survives in this representation) we have for the quark state:
Q+|p,-1/2>=0 (quark) where the 1/2 labels the eigenvalue of J3 spin operator.
For the gluino we can write
Q+|p,-1/2>=Q+Q|p,-1>=(2E-QQ+)|p,-1> ~ |p,-1> (gluon)
I don't understand why can we go from the gluino to the gluon but for the quark (also spin 1/2 like the gluino) the superpartner is a scalar.
