On the Dark Matter Annual Modulation Signal

HEP Theoretical Physics Seminar
Juan Herrero, University of Valencia
May 7, 2013 3:00PM to 4:00PM
Building 362, Room E188
In the first part of the talk, I will review one of the most distinctive signatures of dark matter: its annual modulation direct detection signal, due to the relative motion of the Earth around the Sun.

In the second part, I will focus on (almost astrophysics independent) bounds that can be placed on the annual modulation in terms of the unmodulated event rate and show the results when we apply them to DAMA and CoGENT results [JCAP03(2012)005, 1112.1627 [hep-ph]]. Finally I will show how the unmodulated rate of one experiment can bound the annual modulation seen in another experiment and show the results [PRL 109 (2012) 141301, 1205.0134 [hep-ph]].
