Presentation Transcript

  1. Hydrogen Analysis Software Chris Crawford Jason Seely April 12, 2002 • Topics: • Generator/Reconstruction (Seely) • Radiative Corrections (Crawford) Hydrogen Analysis Software

  2. Reconstruction • Complete simulation cycle • Generator (epel) • M.C. (blastmc) • Recon. (BlastLib) • Analysis (J. Seely) • Studies on polarization asymmetry • New correction scheme (J. Seely) • Improvements made at low Q^2 Hydrogen Analysis Software

  3. z B z B Polarization Asymmetry • Polarization depends on spin alignment along B • A1 asymmetry fromhigher polarizations • A2 from lower pol. • Average the two super-ratios • Simulation is only ideal case Hydrogen Analysis Software

  4. Asymmetries Hydrogen Analysis Software

  5. Reconstruction Hydrogen Analysis Software

  6. Monte Carlo Hydrogen Analysis Software

  7. Radiative Corrections • Results from MASCARAD 1.0 • Modification for arbitrary polarization angle • New event generator MASCGEN • Work in progress • Hard photon and proton kinematics • Feed into BlastMC, and BlastLib2 • Add multiple scattering Hydrogen Analysis Software

  8. MASCARAD • Covariant calculation with no cutoff parameter • A. Afanasev et.al., Phys.Rev.D 64,113009 Hydrogen Analysis Software

  9. 440 MeV R.C. Hydrogen Analysis Software

  10. 880 MeV R.C. Hydrogen Analysis Software

  11. MascGen • Proton and photon kinematics • inelasticity v affects w Hydrogen Analysis Software

  12. Born Events Theta Proton Momentum (GeV) Hydrogen Analysis Software

  13. Radiative Events Theta Proton Momentum (GeV) Hydrogen Analysis Software

  14. Conclusion • All components of analysis cyclehave been implemented • A new R.C. event generator has been written and compared with MASCARAD • Still need to run event generator through BlastMC and BlastLib Hydrogen Analysis Software
