What's left to be done before a W/Z Cross Section Paper
This drupal page outlines a number of things that need to be done or decided on before we publish the W/Z cross sections.
- Write an analysis note
- Simulations
- Do we want/need embedded simulations?
- Do we want/need a new set of simulations?
- Known problems with current MC sample:
- PPV ignores EEMC
- Timestamps for TPC dead padrows don't match data
- Beam line offset is wrong for vertex reco (primary tracks slightly mis-reconstructed)
- Tracking efficiency at mid-rapidity doesn't match data (dominant systematic error)
- Production
- This is reliant on the calibrations question at some level, but do we want a new production of the data? It does only take a day.
- Calibrations
- TPC - Do we want a new round of SC&GL? I don't think its necessary (Gene, your thoughts?)
- BTOW - Need to finalize calibration (and then get energy scale unc.)
- ETOW - What is our energy scale uncertainty? How does it feed into the analysis?
- Luminosity
- Cross check from ZDC (is it possible?)
- Can we reduce the uncertainty?
- Finalize algorithm
- Change to SpT-balance (from pT-balance and awayside pT veto)
- Finalize the Z algorithm as well
- Anything else?
- Finalize background subtraction
- Do we want to keep the 2d variation for the background shapes or only use the SpT-balance variation?
- Do we want to do any further physics subtraction with our background cocktail (i.e. Z's from QCD background shape)
