Parameter Help

Parameter

The parameters of the model are taken from the varsN.mdl file in the models directory. Other parameter values can be used if specified using the "Parameter" keyword. Here is an example:
Parameter:EE=0.31
Parameter:SW=0.481
Parameter:MZ=91.1884
Parameter:wW=2.08895
Any parameters not specified using this keyword in the batch file will be taken from the varsN.mdl file in the models directory. This gives a convenient way of changing the default values of the parameters. Simply open CalcHEP in symbolic mode, choose to edit the model and change the values of the indepenedent parameters. These new values will then become the default values used by this batch program. There is no need to redo the process library.
