v1 v2 18 18 19 19 ===== ''How do I calculate the amplitudes of specific diagrams in specific phase space points using MadGraph ?'' ===== 20 The easiest way to do this is to download the [ :StandAlone:StandAlone MadGraph] package and generate the process. You can then easily choose which diagrams to include in the matrix.f files of the !SubProcesses/P_xx_xxxx directories. There is also an example program in the !SubProcesses directory which shows how to calculate the amplitude at a specific phase space point (answered by Main.JohanAlwall)20 The easiest way to do this is to download the [wiki:StandAlone StandAlone MadGraph] package and generate the process.

I'm not very familiar with the code, so I'm not sure where to start. Thanks'' -- Main.EmilyJohnson - 30 Apr 2008
