SUMMARY:Top Portal Dark Matter\, Theory Seminar (High Energy/Cosmology
 )\, Christopher Jackson\, University of Texas at Arlington
DESCRIPTION:With the recent discovery of the Higgs boson\, much of the
  attention in the particle physics community has turned to illuminatin
 g the true nature of dark matter.  Out of the numerous possible scenar
 ios studied in the literature\, one interesting scenario involves the 
 case where dark matter (much like the Higgs boson) has enhanced coupli
 ngs to the most massive particles in the Standard Model (e.g.\, W and 
 Z bosons\, top quarks and/or the Higgs boson itself).  In this talk\, 
 I will discuss one particular model where dark matter couples exclusiv
 ely to the right-handed top quark (which we dub aEurooeTop portal dark
  matteraEuro or TPDM).  In this situation\, the possibility of detecti
 ng dark matter in direct-detection experiments such as LUX is highly s
 uppressed and one must turn to other types of searches.  I will presen
 t the results of a preliminary study on the feasibility of detecting T
 PDM either at the LHC or through indirect searches.  In particular\, I
  will show that this type of model has very interesting signatures in 
 gamma rays.
