Presentation Transcript

  1. A-single- study using Pythia • What is Ex point for R=Nall/Ndirect=1? • With VETO, Without VETO (VETO: Large cells) • Pythia condition: • MSELL=0, • MSUB=(11,12,13,28,53,68,81,82,86,87,88,89,92,93,94,95,1,2) and (14,18,29,114,115). • inelastic=41.12 [mb] • CKIN(5)=1,CKIN(6)=1,CKIN(3)=0,CKIN(4)=-1. • Select “A single  events” • Acceptance: FPD++ small cells • VETO FPD++ large cells (See page 2) • Results • Without VETO EX=43 GeV (Intersecting point of black and pink histograms in page 3) • With VETO EX=26 GeV (This value can be improved by better choices for "acceptance" and "veto“).

  2. Acceptance (Small cells) Veto (Large cells)
