ALPGEN MC Generation at SPRACE - Event Production

Production for CMS: CMSSW_3_1_X series.

This round of production will consist of:
  • ttbar + 0 to 4 jets (self-requested)
  • W+ 0 to 4 jets in 0 to 100, 100 to 300 pT brackets.
  • Z + 0 to 4 jets in 0 to 100, 100 to 300 pT brackets.
The details of the production will follow what is described in AlpgenProduction31X. All grids can be found in AlpgenGridProductionPage.
