Description
We investigate electroweak bremsstrahlung as a potential search channel for dark matter at the LHC. For illustrative purposes we consider a typical quarkphilic model with a Majorana dark matter candidate. We focus on the emission of a $Z$ boson from either the initial state particles or the internal propagator during annihilation of quarks into dark matter. Among the signatures of such processes will be a pair of high $p_T$ muons that reconstruct to the invariant mass of the $m_Z$, and large amounts of missing energy. We compare this signal to Standard Model backgrounds at the generator level, as a proof of principle for this search channel. We find that in certain regions of the model parameter space, up to 50% signal to background can be achieved, for 14TeV centre of momentum energy.
