Explaining PAMELA and WMAP data through coannihilations in extended SUGRA with collider implications
The PAMELA positron excess is analyzed within the framework of nonuniversal supergravity (SUGRA) models with an extended U(1)n gauge symmetry in the hidden sector leading to neutralino dark matter with either a mixed Higgsino-wino lightest R-parity odd supersymmetric particle (LSP) or an essentially...
