7 December SLHC Calo Trigger Simulation Status Report Kevin Flood, Michail Bachtis University of Wisconsin, Madison

Calorimeter signatures Electrons/Photons –Spatially confined in a cluster of 2x2 trigger towers –Significantly higher ECAL contribution –Isolated e/γ should have low energy deposits in the surrounding area ECAL HCAL Δη x Δφ=0.087x0.087 e/γ ECAL HCAL τ ECAL HCAL jet Taus Confined in 2x3 Clusters 3 prongs/1 prong + π 0 s have wider φ profile Small energy leak in surrounding towers Jets Most of the energy confined in a central core For jets over 20 Gev the energy is included in a 8x8 region η φ η φ η φ

Algorithm Overview Particle Cluster Finder –Takes Calorimeter TPG input and applies tower thresholds –Creates overlapped 2x2 clusters Cluster Overlap Filter –Removes overlap between clusters –Identifies local maxima –Prunes low energy clusters Cluster Isolation and Particle ID –Applied to local maxima –Calculates isolation deposits around 2x2, 2x3 clusters –Identifies particles Jet reconstruction –Applied on filtered clusters –Groups clusters to jets Particle Sorter –Sorts particles and outputs the four most energetic ones per class MET,HT,MHT Calculation –Calculates Et Sums, Missing Et from clusters Original Algorithm E T dependent E/(E+H) selection –3 parameters to tune Recent Additions Tau central tower E T threshold E T threshold to add cluster energy for isolation constant slope threshold
