# Lower bound on the neutralino mass from new data on CMB and implications for relic neutralinos

@article{Bottino2003LowerBO, title={Lower bound on the neutralino mass from new data on CMB and implications for relic neutralinos}, author={Alessandro Bottino and Fiorenza Donato and Nicolao Fornengo and Stefano Scopel}, journal={Physical Review D}, year={2003}, volume={68}, pages={043506} }

In the framework of an effective minimal supersymmetric extension of the standard model without gaugino-mass unification at a grand unification scale, we set a lower bound on the neutralino mass based on the new WMAP data on ${\ensuremath{\Omega}}_{\mathrm{CDM}}$ $(R$-parity conservation is assumed). Our lower bound ${m}_{\ensuremath{\chi}}\ensuremath{\gtrsim}6\mathrm{GeV}$ leaves much room for relic neutralinos significantly lighter than those commonly considered ${(m}_{\ensuremath{\chi…
