• This page describes Physics Analysis Ntuple Package framework (PhysicsAnp)
  • This tutorial describes how to run a complete analysis from DxAOD to final plots


  • PhysicsAnpProd ntuple production framework
    • Git project: ustc/PhysicsAnpProd
    • This is a standalone package that depends on only on ATLAS analysis software
    • This package reads DxAOD, applies CP corrections and produces analysis ntuples - work in progress
    • Tutorial TWiki: PhysicsAnpProd

  • PhysicsAnp framework is made of two core packages
    • Git project: ustc/PhysicsNtuple
    • Two core packages provide core framework functionality:
    • It should not be necessary to modify these packages for regular analysis work

  • Main analysis work is performed with PhysicsAnpLight package
    • Git project: ustc/PhysicsAnpLight
    • This is the main analysis package for SSWW, ttH and prompt lepton work
    • PhysicsAnpLight depends on PhysicsAnpData and PhysicsAnpBase packages
    • Analysis code reads ROOT ntuples
    • Selects electrons, muons, jets, etc
    • Selects and plot events
    • Includes python scripts for making stacked plots and cut-flows
    • Work in progress - currently migrating code from the previous iteration of this package

Brief overview of analysis code

  • Main python configuration module for object and signal region selections

  • Event data classes
    • RecoEvent corresponds to reconstructed event as read directly from input ntuples
    • CandEvent corresponds to candidate event, consisting objects that pass selections and overlap removal

Running up PhysicsAnp code with release 20.7

First time setup

  • This section describes how to set up this code for the first time using release 20.7 of ATLAS analysis software
  • Please run these commands only once and then exit shell:
   $ mkdir -p ~/testarea/AnpBase20
   $ cd ~/testarea/AnpBase20
   $ git clone
   $ source PhysicsAnpLight/macros/setup/ 
   $ exit

  • If "git clone" above fails outside CERN, please try getting CERN Kerberos ticket first:
kinit -f -r7d -A $USER@CERN.CH

Running analysis code

  • Please follow instructions for producing ntuple file with release 20.7 described in this TWiki: PhysicsAnpProd
  • Commands to run analysis code:
   $ cd ~/testarea/AnpBase20
   $ source
   $ python $TestArea/PhysicsAnpLight/macros/ out.root -n 0 -o hist.root

  • Running simple object level cut-flow:
   $ python $TestArea/PhysicsAnpLight/macros/ hist.root -s --hkey=CutConf.* --outdir=cutflows

  • How re-compile all packages when files are updated:
   $ cd $TestArea/PhysicsAnpLight/cmt
   $ cmt bro make -j4

  • How re-compile all packages when new files are added:
   $ cd $TestArea/PhysicsAnpLight/cmt
   $ cmt bro rm -r ../x86_64-slc6-*
   $ cmt bro make -j4
