Constraining the co-genesis of Visible and Dark Matter with AMS-02 and Xenon-100

Abstract

We study a non-thermal scenario in a two-Higgs doublet extension of the standard model (SM), augmented by an U(1)_{\rm B-L} gauge symmetry. In this set up, it is shown that the decay product of a weakly coupled scalar field just above the electroweak scale can generate visible and dark matter (DM) simultaneously. The DM is unstable because of the broken B-L symmetry. The lifetime of DM (\approx 5\times 10^{25} sec) is found to be much longer than the age of the Universe, and its decay to the SM leptons at present epoch can explain the positron excess observed at the AMS-02. The relic abundance and the direct detection constraint from Xenon-100 can rule out a large parameter space just leaving the $B-L$ breaking scale around \approx 2 - 4 TeV.
