Title: Rapidity Gap Events in Squark Pair Production at the LHC
Abstract: The exchange of electroweak gauginos in the t- or u-channel allows squark pair production at hadron colliders without color exchange between the squarks. This can give rise to events where little or no energy is deposited in the detector between the squark decay products. I will talk about the potential for detection of such rapidity gap events at the Large Hadron Collider (LHC). The numerical analysis is divided into two parts. First, the rapidity gap signal is evaluated in a simplified framework at the parton level. The second part covers an analysis with full event simulation using PYTHIA as well as Herwig++, but without detector simulation. The transverse energy deposited between the jets from squark decay is analyzed, as well as the probability of finding a third jet in between the two hardest jets. For the mSUGRA benchmark point SPS1a we find statistically significant evidence for a color singlet exchange contribution.
