Standard Model Processes for LEP2

(189 GeV)

The page contains information about Monte Carlo for standard Model processes for LEP2. All of the Monte Carlo's shown here were generated at 189 GeV. The datasets available are divided by the database used to generate them.

This page is maintained by C. Loomis. Please email any corrections, complaints, etc. to him.

Additional WW Monte Carlo datasets are described here.

NOTE: The cards for the POT files are provided for convenience. However, the MINIs contain nearly the same information, can be run through more quickly, and use less staging space. Therefore, using POTs is strongly discouraged.
