One jet to rule them all: monojet constraints and invisible decays of a 750 GeV diphoton resonance
Abstract : The ATLAS and CMS collaborations have recently reported a mild excess in the diphoton final state pointing to a resonance with a mass of around 750 GeV and a potentially large width. In this work, we consider the possibility of such a scalar resonance being produced via the gluon fusion process and decaying to jets, diphotons and a pair of invisible particles, stable at collider scales. We obtain limits from monojet searches on such a resonance and test its compatibility with the requirement for a large width. We also consider the possibility that this stable, neutral particle is a potential dark matter candidate and investigate the relic density constraints along with the collider limits within such a model. We conclude that monojet searches provide strong constraints in ruling out a large part of the considered parameter space.
