Seminarium "Teoria cząstek elementarnych i kosmologia"

In this talk we review our work on a new proposal for the space-time structure of dark matter. After a brief account of the algebraic structure and quantum field theory for fields with a (1,0)+(0,1) space-time structure described in a Dirac-like spinor language, we focus on the predictions of dark matter with this space-time structure for several observables in an effective field theory approach, and comparison with data including dark matter relic density, direct detection of dark matter (XENON1T results), indirect detection of dark matter (annihilation into standard model particles) and the gamma ray excess from the galactic center, which yields the sharp prediction M=M_{H}/2 for dark matter.
