A General Approach to the Direct Detection of Dark Matter
by Gaudet, Chase J., M.S., University of Louisiana at Lafayette, 2013, 84; 1553881
Abstract (Summary)

It is an exciting time in the direct detection of dark matter. Many experiments are showing a signal, but most of them do not overlap. Our goal was to construct a simple non-relativistic effective field theory of dark matter-nuclei scattering. This is an extension of work done on the subject, but we do not take limiting cases on mediator mass and look at a pseudo-scalar and scalar exchange. With this we looked at how the different astrophysical uncertainties and mediator mass affected the direct detection signal. Using this and dark matter to quark annihilation, we were also able to set bounds on the coupling parameters of the model to within a single order of magnitude. This information could provide insight on how dark matter and nuclei interact by matching actual signals to our data.
