MASSIVE SPINNING SUPERPARTICLE

Abstract

We consider new supersymmetric particle model, describing the massive extension of D=4 spinning superparticle model, derived in Ref. 1. It is shown that our model can be described by the D=5 massless spinning superparticle model after dimensional reduction D=5→D=4 and putting the fifth momentum P5=m. The known massive superparticle and massive spinning particle models can be obtained as special cases. The first quantization of the massive spinning superparticle model gives a N=2 massive vector multiplet (one complex scalar, two Dirac spinors, one massive complex vector field).
