Detailed Description

Implements mu-jet OR optimized for high-pt muons in boosted and highly radiative (jetty) topologies.

This implementation comes from the strong 2Lep SUSY analysis studies which were presented in the SUSY meeting here: https://indico.cern.ch/event/436702

The procedure is two-staged: 1. Remove (non-b-tagged) jets overlapping with muons in an inner delta-R cone (default 0.2). 2. Remove muons overlapping with remaining jets using the sliding delta-R cone. See the SlidingDeltaRMatcher for more info.

Special configuration properties BJetLabel - input decoration flagging b-jets InnerDR - cone in which non-bjets are removed (default 0.2) SlidingDRC1 - constant offset for sliding dR (default 0.04) SlidingDRC2 - mu-pt dividend for sliding dR (default 10GeV) SlidingDRMaxCone - max cone size cutoff for sliding dR (default: off)

int ORUtils::AltMuJetOverlapTool::getNumTracks

(

const xAOD::Jet *

jet

)

const [protected]

Helper method to get the number of tracks in a jet w.r.t. the primary vertex. Returns -1 if no primary vertex is found. TODO: reduce duplication with MuJetOverlapTool.

const xAOD::Vertex * ORUtils::AltMuJetOverlapTool::getPrimVtx

(

)

const [protected]

Retrieve the primary vertex used to count jet tracks. TODO: reduce duplication with MuJetOverlapTool.
