Résumé/abstract:

A number of groups have found tentative evidence for 130 GeV dark matter annihilating into gamma rays at the galactic center, by studying publicly available Fermi/LAT data.  I will discuss two theoretical models which could account for the observations, one where scalar dark matter couples to new charged scalars, and another where fermionic dark matter has a large magnetic moment due to compositeness.  Both models predict distinctive signatures at the LHC, including like-sign lepton pairs and four-photon events, that would allow for the discovery of the new charged particles needed for mediating the dark matter interaction with photons.

Cette conférence est présentée par le Groupe de Physique des Particules du Département de physique de l'Université de Montréal.
