UCI SUSY -- RunII Readiness

Introduction

This twiki page is intended to help organize (complete) the development of the UCI SusyNtuple framework in a clear and transparent way.

Code repository

The code development is ongoing and can be followed on GitHub

• SusyCommon: Code for the production of SusyNt from xAOD
• SusyNtuple: SusyNtuple analysis framework

Development

• For development comments use "//AT foo bar" where "AT" are developer initials
• Test the code as you go

Class Status

Event

• Move event trigger flags ("m_trigFlags") to TBits ("m_evtTrigBits") object

Useful info

Electrons

xAOD electron & sytematics

• truth matching
• trigger matching
• missing chargeflip

Systematics

Useful info

Muons

xAOD Muon

• truth matching
• trigger matching
• error on efficiency SF

Systematics

Useful info

• Muon xAOD content in rel20

Taus

xAOD Taus

• Truth matching
• efficiency SF

Systematics

Useful info

Photons

Jets

xAOD Jets

• bTagging variables
• Currently calibration is not applied --> done within SUSYTools?
• No systematics are implemented yet
• isBadVeryLoose is always false due to "the 'bad' auxdata of jets is not always available."
• matchTruth bit is not set correctly but I think this is tied to the ongoing discussion w/ Estel et al
• Some b-tagging weights that were available in Run-I are either no longer available/supported or will be at some point but not yet
• isBCH bits are not set. Ximo says "[these were not used] at the end during Run-1, so I wouldn't worry about [them now]"
• match to truth jets

Systematics

Useful info

• Flavor tagging Run-II

Met

xAOD MET

Systematics

Useful info

TrackMET

Systematics

Useful info

• example (L763) https://svnweb.cern.ch/trac/atlasinst/browser/Institutes/BNL/SUSYAnalysis/redlinger/stopRun2/stop0lExample/trunk/Root/stop0lExample.cxx

Large-R (reclusted/trimmed) Jets

Systematics

Useful info

• Fastjet user manual
• Jet reclustering twiki
• xAODHelpers

TruthJets / TruthParticles

Trigger

Implement trigger utilities within SusyNtuple

• Event level trigger histo stored in SusyNt
• Get trigger bits from trigger histo using trigger utility (build bit at analysis level)

Release 20

Noted changes

SUSYTools-00-06-02 I have encountered several container name changes (mainly affects calls to TStore/TEvent "retrieve")

• in SusyCommon/XaodAnalysis.cxx : "TruthEvent" --> "TruthEvents" [container name change]
• in SusyCommon/XaodAnalysis.cxx : "TruthParticle" --> "TruthParticles" [container name change]
