The page contains information about Monte Carlo for standard Model processes for LEP2. All of the Monte Carlo's shown here were generated at 183 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.
Other Monte Carlo datasets are listed in the last table. See the additional information for a complete description of these datasets.
10/03/99 | The Zee samples with the high and low cutoffs were switched. |
14/12/98 | The tautau MC samples contained mumu data. This is now fixed. |
12/08/98 | Two WW color reconnection samples were incorrectly listed as qqbar. These have been removed. See WW page for these samples. |
06/08/98 | The cross-section for ZZ production was incorrectly listed here (and in scanbook) as 2.93 pb. The correct value, 2.545 pb, is now listed. |
26/06/98 | New datasets for qqbar and Bhabba scattering have been included. Two samples (WW and 2 photon->hadrons) have been withdrawn from scanbook and removed from this page. |
23/01/98 | FILI cards updated. Several samples have more events. The qqbar fili cards (pythia, DB227) were corrected. They contained some 130 and 136 GeV data because of a script bug. Apologies for any inconveniences. |
16/09/97 | New datasets for MC '97 (HERWIG qq, 4-fermion w scint. in, 2-photon ev,...) |
21/08/97 | more background MC (qq, WW, ZZ) from Wisconsin (MINI only) |
31/07/97 | New MC gg->had and WW |
25/07/97 | New MC for 1997 gg->hadrons, mu+mu-, tau+tau- |
16/07/97 | New mu+mu- and gg->had available |
11/07/97 | New WW MC available | 01/07/97 | gg MC available |
10/06/97 | MINI cards |
05/06/97 | 200 k 2-photon events, additional 100k qqbar 150 k WW with gal305.2 and database 225 (LCAL scintillators) 100k qqbar from SACALY |
12/05/97 | second set of 4-fermion events (gal305.2) |
05/05/97 | bug found (no HCAL muon ineff. maps), executable overwritten; ongoing production (with gal305.1) stopped |
30/04/97 | production started |
