Introduction

This page is intended to gather recommendations together for convenience. It is not an exhaustive list and you should check to make sure that the recommendations you are following and tools you are using are up to date.

Muons

Please see MCP group recommendations (for EPS and LPC) here: https://twiki.cern.ch/twiki/bin/view/AtlasProtected/MCPAnalysisGuidelinesEPS2011

Packages to use in analyses include:

• https://svnweb.cern.ch/trac/atlasoff/browser/PhysicsAnalysis/MuonID/MuonIDAnalysis/MuonMomentumCorrections/tags/MuonMomentumCorrections-00-03-02
• https://svnweb.cern.ch/trac/atlasoff/browser/PhysicsAnalysis/MuonID/MuonIDAnalysis/MuonEfficiencyCorrections/tags/MuonEfficiencyCorrections-00-03-15

Muon Trigger Recommendations

See https://twiki.cern.ch/twiki/bin/viewauth/Atlas/MuonTriggerPhysicsTriggerRecommendations2011

• Periods A-I: Take OR of EF_mu18_MG (or EF_mu18) and EF_mu40_MSonly_barrel
• Period J onwards: OR of EF_mu18_MG_medium (or EF_mu18_medium) and EF_mu40_MSonly_barrel_medium

You must apply a trigger scale factor, based on the pT, eta and phi of the muon (barrel) or pT (endcap). See https://twiki.cern.ch/twiki/bin/viewauth/Atlas/MuonTriggerPhysicsTriggerRecommendations2011#Trigger_Scale_Factor_for_MC10b_E for more details.
