چکیده
We consider d=10 N=1 supersymmetry algebra with maximal number of tensor charges Z and introduce a class of orbits of Z, invariant w.r.t. the T8 subgroup of massless particles’ little group T8 ⋉ SO(8). For that class of orbits we classify all possible orbits and little groups, which appear to be semidirect products of T8 ⋉ SO(k1) × ...SO(kn) form, with k1 + ...kn = 8, where compact factor is spinorially embedded (by triality map) into SO(8). We define actions of little groups on supercharge Q and construct corresponding supermultiplets. In some particular cases we show the existence of supermultiplets with both Fermi and Bose sectors consisting of the same representation of tensorial Poincare. In addition, complete classification of supermultiplets (not restricted to T8-invariant orbits) of orbits, with rank-2 matrix of supersymmetry charges anticommutator, is given.

We consider dimensionally reduced three-dimensional supersymmetric Yang– Mills-Chern–Simons theory. Although the N = 1 supersymmetry of this theory does not allow true massive Bogomol'nyi–Prasad–Sommerfield (BPS) states, we find approximate BPS states which have non-zero masses that are almost independent of the Yang–Mills coupling constant and which are a reflection of the massless BPS states ...

Unlike the Schwarzschild black string in the Randall-Sundrum scenario which is known to have the geodesics reaching the AdS-horizon terminating there, the D=7 extremal BPS selfdual string of N = 2 gauged supergravity potentially differs from this result. I give a complete proof that timelike radial trajectories of the selfdual string solution that escapes to r = ∞ do not see a curvature singula...
