We discuss the possibility of identifying invisible objects (e.g. dark matter) via missing mass in Central Exclusive Processes; that is, in events where only forward protons are detected at the LHC. We show that the signal must have a cross…
We introduce a new kinematic event variable MTGEN which can provide information relating to the mass scales of particles pair-produced at hadronic and leptonic colliders. The variable is of particular use in events with a large number of…
Missing transverse energy significance may be used to help distinguish real missing transverse energy due to undetected particles from spurious missing transverse energy due to resolution smearing. We present a description of the missing…
