Since many changes have been made recently, I would like to clarify MC parameters and make proposal for mass production. I would like to present this at the analysis meeting or HPS weekly meeting in the next few weeks. Any comments/additions/corrections are all welcome. 1) Generator level cuts EGS5 (beam_v5.f) - FEE cut uses 15 mrad. Do we need to lower to 5mrad? - wab cut uses 10 mrad. Do we need to lower to 5mrad? MadGraph -Tritrig alpha=1/137.036 E(e+,e-) > 50 MeV E(e+)+E(e-) > 0.5 GeV |theta_y| > 5 mrad -Wab alpha=1/137.036 E(gamma) > 50 MeV, |theta_y(gamma)| > 5 mrad -ap No cuts, but we need to specify A' mass and ctau. Generator level event generation can be started at SLAC, but we have to make sure the initial random number seeds are different between JLab and SLAC so that we don't duplicate events. 2) Event generation 1.05 GeV Beam background: 100 jobs, 500K bunches each Tritrig: 1000 jobs, 10,000 events each Wab: 1000 jobs, 10,000 events each Rad: 100 jobs, 10,000 events each Ap: 100 jobs, 10,000 events each for each mass. 2.3 GeV Same as 1.05 GeV 3) Detector models There are ~100 detector models. We need to decide which detector model to use for mass production. Please make the list. 4) Which files to save and where. All the generator level files are saved, but only recon files are saved. Since tapes cannot be used at SLAC, do we want to transfer all the recon files to JLab? At SLAC, the files will be saved in /nfs/slac/g/hps3/data/mc_production . This directory tree may need a clean-up. 5) What to generate and at what priority. 1.05 GeV Wab-beam-tri using nominal detector (priority #1) Tritrig-wab-beam using nominal detector (priority #2) 2.3 GeV Wab-beam-tri using nominal detector (priority #3) Tritrig-wab-beam using nominal detector (priority #4) 4.4 GeV Wab-beam-tri using L0 detector Tritrig-wab-beam using L0 detector We need to decide where to generate. Since wab-beam-tri requires a large disk space, JLab might be the only possibility. 6) Spreadsheet We need a spreadsheet based on Google doc that summarizes all the files and production status/priorities. This spreadsheet must be accessible by all the HPS collaborators (read only).
