TeV dark matter in the disk

By Francesco Nozzoli

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.Comment: 5 pages, 7 figure
