Dark matter for excess of AMS-02 positrons and antiprotons

Blog Article

We propose a dark matter explanation to simultaneously account for the excess of antiproton-to-proton and positron PROBIOTIC GUM power spectra observed in the AMS-02 experiment while having the right dark matter relic abundance and satisfying the current direct search bounds.We extend the Higgs triplet model with a hidden gauge symmetry of SU(2)X that is broken to Z3 by a quadruplet scalar field, rendering the associated gauge bosons stable weakly-interacting massive particle dark matter candidates.By coupling the complex Higgs triplet and the SU(2)X quadruplet, the dark matter candidates can annihilate into L-LYSINE 1000MG triplet Higgs bosons each of which in turn decays into lepton or gauge boson final states.Such a mechanism gives rise to correct excess of positrons and antiprotons with an appropriate choice of the triplet vacuum expectation value.

Besides, the model provides a link between neutrino mass and dark matter phenomenology.
