Supersymmetric U(1)B×U(1)L model with leptophilic and leptophobic cold dark matters
چکیده انگلیسی
We consider a supersymmetric model with extra U(1)B×U(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 σSI∼10−3±1 pb can be easily accommodated by leptophobic dark matter (χB) with correct relic density, if the U(1)B gauge boson mass is around 2mχB. Also the PAMELA and Fermi/LAT data can be fit by leptophilic CDM with mass ∼1 TeV. There could be interesting signatures of new fermions and new gauge bosons at the LHC.
