Comprehensive Review and Preparation for Jan. 19 Simulations Meeting

Prepare for the Jan. 19 simulations meeting with a thorough review and discussion of NSAC milestones, physics goals, and performance evaluations. Address key topics such as EM ID, photon and jet performance, Collins and Sivers effects, and more. Plan for upcoming tasks in dAu and explore data analysis for improved insights.

  1. What we will need for Jan 19 in simulations Richard Seto FOCAL meeting Jan 6, 2008

  2. Review • Jan 19 – firm date • Reviewers • Matthias, Elka, Christine, (john H, mike L)

  3. NSAC milestones- Physics Goals  pA physics – nuclear gluon pdf  em1+em2+strips  G  -Jet AuAu  em1+em2 transverse spin phenomena

  4. FOCAL Internal Review • Agenda • Overview • EM ID performance- Sky/edouard/ondrej • photon performance – Sky/edouard/ondrej-richard (richard-geant4) • pi0 peaks 2-track – Sky-Edouard-ondrej-rich • Transverse physics – John L • Jet direction performance - Mickey • pi0 performance in jet – Rich(2track), Richard (geant4) • Collins – Sivers? • Delta G(x) – Mickey • Performance plots gamma/pi0 from richard vs pt and angle- Richard(geant4), Mickey • Possible 2pi0 channel – pythia plots (?) -rich • pA physics – Pythia level • photon isolation+physics limits - rich • jet performance Mickey Carla? • Structure function • AuAu – some performance plots – Carla • pi0, photon performance – Richard(Geant4)

  5. Initial work (Status checks today) • Recode new geometry (Sky) • PISA runs of pp-spin=longitudinal, transverse, pA, AuAu-small amount (Ondrej) • Recode new algorithm of edouards to make NCC module (Edouard/Ondrej) • Code up pi0/gamma stuff (Richard) • Work with mickey to make this available for Delta G? • Find good way to pack information into NCC module (Richard- with help Mickey/Ondrej/Edouard)

  6. Coverage in x ans shat~Qsq shat ~qsq x2

  7. Resolutions • EM • angular – 6mr • energy – 23%/E • Jet (from mickey jet resolution PT

  8. x2 resolution – no radiationDetector smearing only shat~qsq x2 Note: radiative smearing is at least as big as detector smearing (use NNNNNLO QCD) x2

  9. isolatedphotons  q Compton g q gluons  q Annihilation g q qsq = 30, 100, 1000 Task in dAu • present knowledge • NMC data known 2) using this x2 unknown 3) to get this 1) convert this dN/dx2 CTEQ5L x2 x2
