Two important programs are in this directory: the Mathematica calculator and the MadGraph5
model.

1. The Mathematica file is used to calculate the physical masses and couplings.

   Run the following command in the kernel:

   ComputeOutputParameters[InputData, "input.dat", "output.dat", "L"]

   where InputData is a list containing the input parameters and the last argument           
   specifies the representation of the rho meson. "L" means (3,1), "R" means (1,3), "LR" means both are present.

2. The MadGraph5 model is contained in the directory "MadGraphModel". You can just copy the UFO directory "rho" to the "models" directory in your MadGraph5_vx.

3. To interface the two programs, we have provided a python file called "wmg5.py" to generate  a MadGraph5 script using the physical masses and couplings output by the Mathematica calculator.

   Run the command in your terminal:

    python wmg5.py --dataset=fileoutput.dat  --runmode=1 --runtimes=n --scriptname=generateevents

    Please be careful that there is no space on the two sides of the equal sign. 


    Note that for the MadGraph_v1 and MadGraph_v2, the meaning of the runmode is different, make sure that you give the right number.
