Instructions :

1) Setup root (/cvmfs/sft.cern.ch/lcg/releases/LCG_96/ROOT/6.18.00/x86_64-centos7-gcc8-opt/bin/root)

2) Go to: http://madgraph.phys.ucl.ac.be/

3) Create an account and download MadGraph5 _aMC@NLO

4) Create a directory that you will be running in and put the tar file in that directory

or you can just copy the file: cp /raid03/users/abbott/madgraph-muoncollider/MG5_aMC_v2.7.2.tar.gz .

5) Execute the folloeing commands:

>tar xvzf MG5_aMC_v2.7.2.tar.gz

>cd MG5_aMC_v2_7_2

>./bin/mg5_aMC. [This will take you to the madgraph interactive terminal]

6)Then:

install pythia8 (this will take some time, but you only need to do it once)

install Delphes (this will take some time, but you only need to do it once)


generate mu+ mu- > w+ w-

output mumuww

exit


>cd mumuww

>cd Cards

>cp /raid03/users/abbott/madgraph-muoncollider/MG5_aMC_v2_7_2/mumuww/Cards/delphes_card_MuonColliderDet.tcl . (This was the card mentioned in Scarlet's talk)

>cp delphes_card_MuonColliderDet.tcl delphes_card.dat


>mkdir MuonCollider

>cd MuonCollider

>cp /raid03/users/abbott/madgraph-muoncollider/MG5_aMC_v2_7_2/mumuww/Cards/MuonCollider/*.* . (cp the .tcl files from MuonCollider git repository)


>cd ../../..

>./bin/mg5_aMC

launch mumuww

1

2

0

0


This should create 10000 mu+ mu- > w+ w- events located at mumuww/Events/run_01/tag1_delphes_events.root

If you run a second time, the file will be located at mumuww/Events/run_02/tag1_delphes_events.root

Note if you run a second time, make sure you change the random seed in run_card.dat or else your second run will be identical to your first run

[run_card.dat is located in MG5_aMC_v2_7_2/mumuww/Cards/

Also when you run a second time, you no longer need to type

1

2

when running since Pythia and Delphes are already set to run

you only need to type

0

0


i.e ./bin/mg5_aMC

launch mumuww

0

0

You should find the cross section to be .0371


This will only take a few minutes


You can find a root file at

/raid03/users/abbott/madgraph-muoncollider/MG5_aMC_v2_7_2/mumuww/Events/run_02/tag_1_delphes_events.root
