PP-Waves, M-Theory and Fluxes

چکیده
We study a new type of warped compactifications of M-theory on eight manifolds for which nowhere vanishing covariantly constant spinors of indefinite chirality on the internal manifold can be found. We derive the constraints on the fluxes and the warp factor following from supersymmetry and the equations of motion. We show, that the lift of Type IIB PP-waves to M-theory is a special type of solution of this general class of models. We comment on the relation between the Type IIB version of such compactifications as a dual description of the Polchinski-Strassler solution describing a four-dimensional confining gauge theory.

PP-waves from rotating and continuously distributed D3-branes
We study families of PP-wave solutions of type-IIB supergravity that have (light-cone) time dependent metrics and RR five-form fluxes. They arise as Penrose limits of supergravity solutions that correspond to rotating or continuous distributions of D3-branes. In general, the solutions preserve sixteen supersymmetries. On the dual field theory side these backgrounds describe the BMN limit of N =...

Solar model predictions of B and p-p neutrinos agree with the experimentally-determined fluxes (including oscillations): φ(pp)measured = (1.02±0.02±0.01)φ(pp)theory, and φ( B)measured = (0.88± 0.04±0.23)φ(B)theory, 1σ experimental and theoretical uncertainties, respectively. We use improved input data for nuclear fusion reactions, the equation of state, and the chemical composition of the Sun. ...
متن کاملM - theory PP - Waves , Penrose Limits and Supernumerary Supersymmetries
We study supersymmetric pp-waves in M-theory, their dimensional reduction to D0-branes or pp-waves in type IIA, and their T-dualisation to solutions in the type IIB theory. The general class of pp-waves that we consider encompass the Penrose limits of AdS p × S q, but includes also many other examples that can again lead to exactly-solvable massive strings, but which do not arise from Penrose l...
