SupersymmetricB−Ldark matter model and the observed anomalies in the cosmic rays
Physical Review D
We propose a simple model of supersymmetric dark matter that can explain recent results from PAMELA and ATIC experiments. It is based on a U(1)_B-L extension of the minimal supersymmetric standard model. The dark matter particle is a linear combination of the U(1)_B-L gaugino and Higgsino partners of Higgs fields that break the B-L around one TeV. The dominant mode of dark matter annihilation is to the lightest of the new Higgs fields, which has a mass in the GeV range, and its subsequent decaydoi:10.1103/physrevd.79.075005 fatcat:gtpjavepxnay3kfkd6o2sd272e
