Searching for light WIMPs via their interaction with electrons

In the present work we examine the possibility of detecting light dark matter particles in the few MeV region via their interactions with electrons. We analyze theoretically some key issues involved in such a detection and perform calculations for the expected rates, for electron recoils as well as...

Description
Summary:In the present work we examine the possibility of detecting light dark matter particles in the few MeV region via their interactions with electrons. We analyze theoretically some key issues involved in such a detection and perform calculations for the expected rates, for electron recoils as well as spin induced atomic excitations, in the context of reasonable theoretical models.
