v 2 1 7 N ov 1 99 7 Topological Extensions of Noether Charge Algebras carried by D - p - branes

We derive the fully extended supersymmetry algebra carried by D-branes in a massless type IIA superspace vacuum. We find that the extended algebra contains not only topological charges that probe the presence of compact spacetime dimensions but also pieces that measure non-trivial configurations of the gauge field on the worldvolume of the brane. Furthermore there are terms that measure the cou...

If neutrino conversions within the Sun result in partial polarization of initial solar neutrino fluxes this gives a new opportunity to distinguish Majorana and Dirac neutrinos by measuring the differential ν e e-scattering cross section in solar neutrino detectors. The partial polarization of Majorana neutrinos produced by the effective ν e L → ˜ ν e R-conversions in solar magnetic fields might...

I argue that, within the Closed-Time-Path formalism, pinch singularities do not appear in truly out of equilibrium situations.

A derivation of the Lax pair for the (1 + 1)-dimensional non-linear σ-model is described. Its main benefit is to have a clearer physical origin and to allow the study of a generalization to higher dimensions. PACS: 11.10.Kk, 11.30.-j , 11.30.Ly
