Detailed Description

Calculate isolation variables for jets and set them as jet attributes.

Properties: IsolationCalculations: List of calculations to perform (see below) InputConstitContainer: name of the jet constituents container RhoKey: EventDensity key. Required in case the PtPUsub calculation is performed.

The isolation variables are calculated from a list of input constituents. which are close to the jet but not part of its constituents. There are multiple options to find this list and then to calculate the
variables. They are passed to the tools by giving a list of string identifiers through the IsolationCalculations property as in

IsolationCalculations = ["IsoKR:11:Perp","IsoKR:11:Par", "IsoFixedCone:10:SumPt",]

where the strings have the form "ISOCRITERIA:NN:VAR"

• ISOCRITERIA : encode the method used to find isolation particles (IsoKR, IsoDelta, IsoFixedCone, IsoFixedArea, Iso6To8, signification detailed below)
• NN : encode the value of the main parameter of ISOCRITERIA : the actual parameter used is NN/10. (same convetion as jet radius in JetContainer names)
• VAR : encode the variable to be calculated (Per, Par, SumPt, P, significations detailed below)

The resulting attribute name is simply the identifier string with ':' removed. Example "IsoKR:11:Perp" -> "IsoKR11Perp"

The input particles container from which constituents come from must be specified in the ConstituentContainer property. This must correspond to an IParticleContainer in the event store. (longer term : make it possible to pass PseudoJetContainer)

Because of the multiplicity of possible isolation and calculation choices, the internal code is modularized. The code is potentially slow (~O(Nconstit x Njet x Nisovariable)) and could be improved if needed by using fast look-up map and/or preselecting constituents.

WARNING: The constituents must be the same in-memory objects as the jet constituents.

Isolation Criteria ("param" below is the main parameter) :

• IsoKR : iso area == cone of size jetRadius*param
• IsoDelta : iso area == cone of size jetRadius+param
• IsoFixedCone : iso are == cone of size param
• IsoFixedArea : iso are == cone of size sqrt(jetRadius*jetRadius+param/M_PI)
• Iso6To8 : iso area == annulus between R=0.6 and R=0.8

Isolation Variables (iso4vec = sum of 4-vec in isolation area, not part of jet)

• Pt : iso4vec.Pt/ jetPt
• PtPUsub : (iso4vec.Pt-rho*isoArea)/ (jetPt - rho*jetArea)
• Perp : iso4Vec.Perp( jetDirection )/ jetPt
• Par : iso4Vec.Dot( jetDirection )/ jetPt
• SumPt : sum Pt of 4-vec contibuting to iso4Vec / jetPt
• P : iso4Vec.Vect().Mag()/ jetPt

getKey()

Get the (hashed) key of an object that is in the event store.

This is a bit of a special one. StoreGateSvc and xAOD::TEvent both provide ways for getting the SG::sgkey_t key for an object that is in the store, based on a bare pointer. But they provide different interfaces for doing so.

In order to allow tools to efficiently perform this operation, they can use this helper function.

ptr	The bare pointer to the object that the event store should know about

Returns

The hashed key of the object in the store. If not found, an invalid (zero) key.
