نویسنده
چکیده
We study the problem of covariant separation between first and second class constraints for the D = 10 Brink-Schwarz superparticle. Opposite to the supersymmetric light-cone frame separation, we show here that there is a Lorentz covariant way to identify the second class constraints such that, however, supersymmetry is broken. Consequences for the D = 10 superstring are briefly discussed.

We show that the massless higher spin four-dimensional particle model with bosonic counterpart of N = 1 supersymmetry respects SU(3, 2) invariance. We extend this particle model to a superparticle possessing SU(3, 2|1) supersymmetry which is a closure of standard four-dimensional N = 1 superconformal symmetry SU(2, 2|1) and its bosonic SU(3, 2) counterpart. The new massless higher spin D = 4 su...
متن کاملThe Jacobi identity for Dirac-like brackets
For redundant second-class constraints the Dirac brackets cannot be defined and new brackets must be introduced. We prove here that the Jacobi identity for the new brackets must hold on the surface of the second-class constraints. In order to illustrate our proof we work out explicitly the cases of a fractional spin particle in 2 + 1 dimensions and the original Brink-Schwarz massless superparti...
متن کاملUniform Twistor–Like Formulation of Massive and Massless Superparticles with Tensorial Central Charges
We construct the manifestly Lorentz-invariant twistorial formulation of the N = 1 D = 4 superparticle with tensorial central charges which describes massive and massless cases in a uniform manner. The tensorial central charges are realized in terms of even spinor variables and central charge coordinates. The full analysis of the number of conserved supersymmetries has been carried out. In the m...
متن کاملNew Superparticle Models Outside the HLS Supersymmetry Scheme
We consider the superparticle models invariant under the supersymmetries with tensorial central charges, which were not included in D = 4 Haag-LopuszanskiSohnius (HLS) supersymmetry scheme. We present firstly a generalization of D = 4 Ferber-Shirafuji (FS) model with fundamental bosonic spinors and tensorial central charge coordinates. The model contains four fermionic coordinates and possesses...
متن کاملTensorial Central Charges and New Superparticle Models with Fundamental Spinor Coordinates
We consider firstly simple D = 4 superalgebra with six real tensorial central charges Zμν , and discuss its possible realizations in massive and massless cases. Massless case is dynamically realized by generalized Ferber-Shirafuji (FS) model with fundamental bosonic spinor coordinates. The Lorentz invariance is not broken due to the realization of central charges generators in terms of bosonic ...
