MCatNLO Step 2

In this step we will have MCatNLo produce $t{\bar {t}}$ events-files. To do this we will:

• Build the executable
• Construct the BASIC input files
• Produce X event files containing Y events each using automated scripts

1) Build the executable

First go the the directory with the MCatNLO code:

cd /MyMCatNLO/EXECUTABLE/

Then construct an input file in the same way as you did for the integration step.

cp MCatNLO.inputs.Integration MCatNLO.inputs.EventGeneration

In this file you only need to change one line:

BASES=OFF

The build the executable, first remove the directory called Linux (this contains the executable that was used for the integration step). After that, simply build the executable:

rm -Rf Linux 
./MCatNLO.inputs.EventGeneration

This will create in a directory called Linux the executable called TTbarNLO_EXE_THISLIB
