Description

Three dark matter direct detection experiments (DAMA, COGENT and CRESST) have reported a possible signal of WIMP interaction corresponding to very light particles, close to the edge of the XENON-100 and CDMS sensitivity. Imposing the latest constraints from colliders, flavour physics, electroweak precision tests and dark matter searches, we show that viable MSSM scenarios with a light neutralino, in agreement with all the present data, are feasible. An analysis of the characteristics of the resulting scenarios will be presented.
