Detailed Description

A tool implementing a specialized tau-jet overlap removal.

This tool was implemented by request for the h->bbtautau analysis which uses a loose-ish btag working point and also considers anti-tau ID.

Object precedence: ID-tau > bjet > anti-tau > light-jet

The procedure works as follows. 1. Remove bjets overlapping with ID taus. 2. Remove anti-taus from remaining bjets. 3. Remove light jets from remaining ID-taus and anti-taus.

To fully utilize the above procedure you have to set the following properties:

AntiTauLabel: The user-set decoration name labeling anti-taus. E.g., "isAntiTau". Default is empty, which disables anti-taus.

BJetLabel: The usual user-set decoration name labeling bjets. E.g., "isBJet". Default is empty, which disables bjet OR.

Member Function Documentation

bool ORUtils::TauAntiTauJetOverlapTool::isBJet

(

const xAOD::Jet &

jet

)

const [protected]

Is this jet a b-jet? Returns false if bjet ID not configured. Does not check if the jet is "surviving" OR.

bool ORUtils::TauAntiTauJetOverlapTool::isSurvivingAntiTau

(

const xAOD::TauJet &

tau

)

const [protected]

Is this an anti-tau? Returns false if anti-tau ID not configured. This one does check if the tau is "surviving" OR.
