Description

One of the major challenges in particle physics, astrophysics and cosmology is the elucidation of the nature of dark matter. There are several pieces of evidence for its existence such as galaxy rotation curves, relic density and those derived from the observation of the cosmic microwave background. A great effort has been put in the measurement of observables that could constrain the properties of this type of matter, that conforms 26% of the energy budget in the universe. These observables include dark matter interactions with standard model particles in direct, indirect and collider searches. The purpose of this talk is to introduce Tensor Dark Matter as an alternative description of dark matter, whose fields transform in the (1,0)+(0,1) representation of the Homogeneous Lorentz Group, and we will show that several experimental bounds, including the Gamma-Ray Excess from the center of our Galaxy and the Cosmic-Ray Antiproton Excess, are consistent with Tensor Dark Matter with a mass around half of the Higgs boson mass.
