Actual Physics behind Mono-X

Understand

Mono-X searches are standard dark matter search strategies at the LHC.

• First, we show how in the case of initial state radiation they essentially collapse to mono-jet searches.
• Second, we systematically study mono-X signatures from decays of heavier dark matter states.
• Direct detection constraints strongly limit our MSSM expectations, but largely vanish for mono-Z and mono-Higgs signals once we include light NMSSM mediators.
