Bounds on annual modulation signal in dark matter direct detection

 I will show  constraints on the annual modulation signal in

Dark Matter direct detection experiments which assume only very

general properties of dark matter halo. The derivation of the bound

uses an expansion in the earth velocity and is expressed in terms of

the unmodulated event rate. I will illustrate the bounds by applying

them to the annual modulation signals reported by the DAMA and CoGeNT

experiments in the framework of spin-independent elastic scattering.

While the DAMA signal satisfies our bounds, severe restrictions on the

DM mass can be set for CoGeNT. Finally, I will also review the

constraints on light dark matter interpretation of the CRESST-II

results.
