Probing dark matter streams with DAMA and CoGeNT
Natarajan, Aravind (Carnegie Mellon University)

I discuss the DAMA and CoGeNT dark matter direct detection experiments and show that the annual modulation effect is an excellent probe of cold dark matter streams. Such streams are expected due to late infall of dark matter on to the Galaxy, and also due to the breakup of satellite halos. I show that alternatives to the Maxwellian halo are consistent with the DAMA results both in amplitude and in phase, for large WIMP masses. Different halo models may be distinguished using the results from two different experiments such as DAMA and CoGeNT. I also discuss the prospects for detecting streams using future results from CoGeNT.
