Massive Superparticle with Tensorial Central Charges


We construct the manifestly Lorenz-invariant formulation of the N = 1 D = 4 massive superparticle with tensorial central charges. The model contains a real parameter k and at k 6= 0 possesses one κ-symmetry while at k = 0 the number of κ-symmetry is two. The equivalence of the formulations at all k 6= 0 is obtained. The local transformations of κ-symmetry… (More)
