Abstract
Different mechanisms operate in various regions of the MSSM parameter space to bring the relic density of the lightest neutralino, $$\tilde{\chi }^0_{1}$$χ~10, assumed here to be the lightest SUSY particle (LSP) and thus the dark matter (DM) particle, into the range allowed by astrophysics and cosmology. These mechanisms include coannihilation with some nearly degenerate next-to-lightest supersymmetric particle such as the lighter stau $$\tilde{\tau }_{1}$$τ~1, stop $$\tilde{t}_{1}$$t~1 or chargino $$\tilde{\chi }^\pm _{1}$$χ~1±, resonant annihilation via direct-channel heavy Higgs bosons H / A, the light Higgs boson h or the Z ..
