TeV dark matter in the disk

TL;DR

This paper reanalyzes various dark matter detection data considering a rotating halo, suggesting high-mass dark matter particles in a corotating flux could explain multiple experimental signals and cosmic ray excesses.

Contribution

It introduces the possibility of a rotating halo with high-mass dark matter particles to unify signals from different experiments.

Findings

DAMA data favor high-mass, corotating dark matter particles.

High-mass, low-velocity dark matter could explain multiple experimental excesses.

Potential link to cosmic ray positron/electron excesses.

Abstract

DAMA annual modulation data and, CoGeNT, CDMS-II, EDELWEISS-II, CRESST excesses of events over the expected background are reanalyzed in terms of a dark matter particle signal considering the case of a rotating halo. It is found that DAMA data favor the configurations of very high mass dark matter particles in a corotating cold flux. A similar high-mass/low-velocity solution would be compatible with the observed events in CoGeNT, CDMS-II, EDELWEISS-II and CRESST experiments and could be of interest in the light of the positron/electron excess measured by Pamela and Fermi in cosmic rays.
