Herwig is a program used by particle physicists to help predict
and understand the data from an accelerator experiment. You must first
run a modified version of isasugra(isawig) to describe the type of
super-symmetric model you wish to study from the ISAJET PAGE. Then you can choose the option from the output page of isasugra to run Herwig events using the decay table created by isawig. This will lead you back to a Herwig form where you can choose beam type, interaction energy, and processes that you are interested in studying, as well as the number of events to be produced.
          The standard output from Herwig will contain a detailed listing of
the first event, and a short summary of all the events run that includes
the cross section for the set of events. The cross section is proportional
to the probability that these events will be created given the input data
you specified.
