The polarization of M5 branes and little string theories with reduced supersymmetry
We construct an M-theory dual of a 6 dimensional little string theory with
reduced supersymmetry, along the lines of Polchinski and Strassler. We find
that upon perturbing the (2,0) theory with an R-current, the M5 branes polarize
into a wrapped Kaluza Klein monopole, whose isometry direction is along the R
current. We investigate the properties of this theory.Comment: 22 pages, late
Supersymmetries and constants of motion in Taub-NUT spinning space
We review the geodesic motion of pseudo-classical spinning particles in
curved spaces. Investigating the generalized Killing equations for spinning
spaces, we express the constants of motion in terms of Killing-Yano tensors.
The general results are applied to the case of the four-dimensional Euclidean
Taub-NUT spinning space. A simple exact solution, corresponding to trajectories
lying on a cone, is given.Comment: 33 pages, LaTeX2e, to appear in Fortschritte der Physi
