Model Help

Model

The first section of the batch file should contain the specification of the model. This is done by model name and should match exactly the name in the CalcHEP model list. So, if you want to scan the "Standard Model(CKM=1)", you would specify this with the batch file line:
Model:Standard Model(CKM=1)
There is no default for this line. It must be included.

Gauge

The gauge of the calculation should also be specified in this section. Choices are Feynman and unitary gauge. CalcHEP is much better suited to calculation in Feynman gauge, but there may be times that unitary gauge is useful. This can be specified using the keyword "Gauge" as in:
Gauge:unitary
The default is Feynman.

Virtual W/Z Decays

CalcHEP allows decays of particle such as the Higgs to decay via off-shell W and Z bosons. This behavior can be controled by the key phrase "Virtual W/Z decays" as in:
Virtual W/Z decays : Off
The default is "On".
