New or $\nu$ Missing Energy? Discriminating Dark Matter from Neutrino Interactions at the LHC

Understand

Missing energy signals such as monojets are a possible signature of Dark Matter (DM) at colliders.

• However, neutrino interactions beyond the Standard Model may also produce missing energy signals.
• In order to conclude that new "missing particles" are observed the hypothesis of BSM neutrino interactions must be rejected.
• In this paper, we first derive new limits on these Non-Standard neutrino Interactions (NSIs) from LHC monojet data.
