The accurate measurement of galactic rotation curves,the CMB spectrum, the primordial abundances of lightelements, together with our understanding of structureformation provide convincing evidence in favor of theexistence of Dark Matter (DM) [1]. While the MA-CHOs searches [2] indicate that an astrophysical solu-tion is rather unlikely, most efforts are now concen-trated on searches for Weakly Interacting Massive Par-ticles (WIMPs) [3]. These particles would belong to theCold Dark Matter scenario (CDM); they would annihi-late and suffer from negligible damping effects at a cos-mological scale. Considering fermions only and assum-ing Fermi interactions, it was concluded [4] that the relicdensity argument constrains the DM mass (m
