Abstract
We consider a supersymmetric model with extra U(1)BÃU(1)L gauge symmetry that is broken spontaneously. Salient features of this model are that there are three different types of cold dark matter (CDM) candidates, and neutral scalar sector has a rich structure. Light CDM with ÏSIâ¼10â3±1 pb can be easily accommodated by leptophobic dark matter (ÏB) with correct relic density, if the U(1)B gauge boson mass is around 2mÏB. Also the PAMELA and Fermi/LAT data can be fit by leptophilic CDM with mass â¼1 TeV. There could be interesting signatures of new fermions and new gauge bosons at the LHC.
