  1. BEMC low-pt pi0 efficiency study dau 200 L. Bland, E. Braidot, A. Ogawa

  2. General parameters Requested by: JLC PWG Reasoning: Needed for FMS-BEMC correlation study Task: study of low-pT(below 2.5GeV) pi0 finding efficiency Beam: dAu 200 Vertex: <X>= 0 σx = 0.01 <Y>= 0 σy = 0.01 <Z>= 0. σz = 60 Zcut = +- 200 StarSoft local

  3. Generator Generator: Hijing 1.383 Minbias Control file: ' Frame/Energy ' 'CMS' 200. ' Projectile type/A/Z ' ‘A' 2 1 (heading west/+z) ' Target type/A/Z ' ’A' 197 79 (heading east/-z) ' Impact parameter min/max (fm) ' 0. 20 ' Jet quenching (1=yes/0=no) ' 0 ' Hard scattering/pt jet ' 0 -1 (no upper limit) ' Max # jets per nucleon (D=10) ' 10 ' Set ihpr2(11) and ihpr2(12) ' 1 (baryon prod model) 1(decay) ' Set ihpr2(21) and ihpr2(18) ' 1(history) 0(B production) ' set B production ' 1.5 ' istat=1 old istat>1 new ' 2 ' Set ihpr2(6) ' 0 and 1 (see next page)

  4. Statistics Total 0.3 M events 0.15M with shadowing off ihpr2(6)=0 0.15M with shadowing on ihpr2(6)=1 StarSoft local

  5. Geometry • Geometry y2008a StarSoft local

  6. Resources Lidia estimated (and akio modified) • dAu 200GeV, Hijing with year 2008 geometry – 0.3M total events; • total reco files size = 0.5TB • fzd = 0.3TB • CPU = 8000 hours for reco, + ~50% for geant simulation; • total CPU ~ 13000 hours; • total size ~ 0.8TB; StarSoft local

  7. Approval from JetCorr-PWG Date: Mon, 28 Sep 2009 21:10:50 +0430 From: Lanny Ray <ray@physics.utexas.edu> To: Akio Ogawa <akio@rcf2.rhic.bnl.gov> Subject: Re: 2008 dAu/Hijing Simulation request HI Akio: Your simulation request is reasonable and I approve it. Lanny StarSoft local
