Abstract

The purpose of my proposed one year visit to Princeton University, is to interact with the Dark Side collaboration. Princeton has a strong leadership in this dark matter direct detection experiment. Our main goal is to link my recent research to this kind of experiment. I have been investigating specific dark matter intrinsic properties, such as boosted interaction cross-sections and also their self-interaction. As an example of our results, we have determined which signatures these properties will imprint on indirect dark matter detection experiments. The collaboration with this group in Princeton will expand this research. As an initial goal, we will discuss and analyze these and other intrinsic properties, and how they can affect signatures in direct detection. Another goal, is to deepen our experimental knowledge, and all the new techniques involved in such experiments. This effort will certainly open new frontiers in our research. The Dark Side Experiment has liquid Argon as its target and a two-phase Time Projection Chamber. It is one of the leading dark matter direct detection experiments, with a sensibility to determine interaction cross sections to the $10^{-45}$~cm$^2$ level. The collaboration with this group will be an unique opportunity to expand our research, and to deepen our knowledge and effort on the dark matter search. (AU)
