Improving generators

• Apply internal radiative corrections
• Incorporate Al target window scattering effects
• Realistic vertex z sampling
• Realistic beam angle and offset at target
• Beam-target-spectrometer misalignments
• Pair-production effects–radiated γ’s either from external Brems. or decays from hadronic final states turning back into electrons (How big is this effect?)
• Explore alternative sampling techniques
• pre-vertex multiple scattering (done, thanks Seaemus)
• Refine inelastic ep gen. to include more accurate FF’s and σT (Partly done or done, thanks Seamus)
• Incorporate depolarization effects into generators (small effect)
• Implement Pion generator (Much work already done here, thanks Seamus)
• High statistics benchmarking of Møller generator using GEANT physics
• Benchmark pre-vertex radiative effects using GEANT
• Externalize generators to speed up simulation
• Low angle scattering (GEANT physics or generator?) for Lumi studies
• Incorporate false asymmetries and helicity correlated effects (Similar to Jim Birchall’s Qweak studies) – can use to study,for example, impact of asymmetric acceptances...
