Seminario di Fenomenologia delle Particelle Elementari

The discovery of signatures compatible with dark matter candidates at the LHC would be a revolutionary milestone for particle physics and cosmology. A discovery, however, would require a deep understanding of the properties of the new state, in order to embed it into a theoretically motivated scenario of new physics. I will explore the possibility to distinguish and characterise the spin of dark matter candidates at the LHC in different scenarios. I will consider the effective field theory approach and simplified models and show how in some scenarios the DM spin can be partly correlated with the shape of relevant kinematic distributions.
