The WIMP limit set by the Xenon10 experiment in 2007 signals a new era in direct detection
of dark matter, with several large-scale liquid target detectors now under construction. A …

Recently published results from the PAMELA experiment have shown conclusive evidence
for an excess of positrons at high (∼ 10–100 GeV) energies, confirming earlier indications …

We sift the impact of the recent Higgs precise measurements, and recent dark matter direct
detection results, on the dark sector of an electroweak extension of the Standard Model that …

If dark matter possesses a lepton number, it is natural to expect the dark-matter annihilation
and/or decay mainly produces the standard model leptons, while negligible amount of the …

Dark matter annihilation in Galactic substructure will produce diffuse gamma-ray emission of
remarkably constant intensity across the sky, making it difficult to disentangle this Galactic …

This paper provides a comprehensive discussion of neutralino dark matter within classes of
extended supersymmetric models referred to as the USSM containing one additional SM …

Recently the PAMELA experiment has released its updated anti-proton flux and anti-proton
to proton flux ratio data up to energies of≈ 200GeV. With no clear excess of cosmic ray anti …

We consider the cosmology of a model in which the dark matter is part of a nonminimal
hidden sector which is not in thermal equilibrium with the standard model particles at the …

We take a fresh look at high energy radioactive nuclei data reported in the 90's and at the
positron data recently reported by PAMELA. Our aim is to study the model independent …

The origin of the e^+ e^-511 keV line observed by INTEGRAL remains unclear. The rate and
morphology of the signal have prompted questions as to whether dark matter could play a …
