Presentation Transcript

  1. Update on W+jets background • As discussed in last topwg meeting, W+jets samples for topwg have been redefined • Alpgen W+2,3,4,5 jet • 8240-8243 Wenu 8244-8247 Wmunu 8248-8251 Wtaunu • Truth filter 3 jets pT>30 (Instead of 4 jets pT>30 GeV) • Status as of 27/11/06 • Python jobOptions modified, committed to DC3_jobOptions CVS and included in production release 12.0.31(5) • jobOptions files now contain additional info (in comment block) on luminosity, cross section and filter, MLM efficiencies • Input ME files from SUSY WG have been repackaged in chunks of appropriate size, reregistered in DQ2 • jobOptions and ME accessibioity fully validated (each job produces sufficient number of events, no crashes etc) • Waiting for jobs to be submitted (by Borut) Wouter Verkerke, NIKHEF

  2. Update on W+jets background • Propose to not process W+2 parton samples -Lots of events for e/t modes due to inefficient filtering (SL electron/tau is often counted as jet) -Tiny contribution to W+4jet final state (filtering output behaves differently because it is effectively a W+3jet f.s.) • 1fb-1 amounts to 550Kevt with W+2p to 320K without • Currently have MEs for a consistent set of ~1fb-1 Wouter Verkerke, NIKHEF
