We construct higher-spin N=1 super algebras as extensions of the super Virasoro algebra containing generators for all spins s ≥ 3/2. We find two distinct classical (Poisson) algebras on the phase super space. Our results indicate that only one of them can be consistently quantized.

By using Heterotic SUSY path integral, one version and generali zation of an integrability theorem due to Mayer is obtained.

In this lecture, we give a brief review of what theorists now know, understand, or guess about static and kinetic properties of quark–gluon plasma. A particular attention is payed to the problem of physical observability, i.e. the physical meaningfulness of various characteristics of QGP discussed in the literature.

Spin-flavor symmetry breaking in the levels of excited Baryons are studied to leading order in the 1/N c expansion. This breaking occurs at zeroth order. For non-strange Baryons with a single quark excited, it is shown that to first order of perturbation theory the breaking is given by one 1-body operator (spin-orbit), and three 2-body operators, all involving the orbital angular momentum of th...
