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 are written out. It is considered the using of index spinor for construction of the tensorial central charges. It is obtained the equivalence at classical level between the massive D = 4 superparticle with one κ-symmetry and the massive D = 4 spinning particle PACS numbers: 11.15.-q, 11.17.+y, 02.40.+m, 11.30.Pb
