cmt co Event/xAOD/xAODTruthCnv

cd Event/xAOD/xAODTruthCnv/cmt

cmt config


cd ../

mkdir run

cd run

cp ../share/* .

Open the file called

mg5_aMC: madgraph+MC@NLO [lxplus]

The output of MadGraph is LHE File, while the input for a Rivet Analysis is a hepmc file. So the first step is to install the following converter: lhef2hepmc.tar.gz After unpacking, you can install it via the command

make HEPMC_PREFIX=/home/student/local/common

Then you can run the code


Then you can run RIVET on that file

rivet -a MC_MCNET2014 OUTPUT.HEPMC rivet-mkhtml Rivet.yoda

Powheg / Powheg OTF

Setup and run Powheg OTF on lxplus (tested with athena version -see setup below-)

POWHEG-BOX-V2 release: 2819

mkdir testarea/
cd testarea/

Download packages:

In additional: download POWHEG-BOX-V2 processes and compile them inside POWHEG-BOX

NOTE: to compile HVJ change the FC compiler to gfortran inside the Makefile.

(1) MC14JobOptions

  • modify JO in share/
  • modify gencontrol/ to add relevant processes
  • modify/add gencontrol/PowhegControl_<process>.py to add/modify relevant processes
(2) POWHEG-BOX-V2: download and compile

My Personal Preferences

  • Show tool-tip topic info on mouse-over of WikiWord links, on or off:

  • Preference for the editor, default is the WYSIWYG editor. The options are raw, wysiwyg:
    • Set EDITMETHOD = wysiwyg

  • More preferences TWiki has system wide preferences settings defined in TWikiPreferences. You can customize preferences settings to your needs: To overload a system setting, (1) do a "raw view" on TWikiPreferences, (2) copy a Set VARIABLE = value bullet, (3) do a "raw edit" of your user profile page, (4) add the bullet to the bullet list above, and (5) customize the value as needed. Make sure the settings render as real bullets (in "raw edit", a bullet requires 3 or 6 spaces before the asterisk).
