=============================================================================== MET-tasks: =============================================================================== Unclustered energy studies ========================== manpower : 2 Ph.D/postdoc timescale : 6-9 months contacts : Ashish Kumar, Robert Kehoe, Kirti Ranjan and Brajesh C. Choudhary (z->ee studies), Sophie Trincaz-Duvoid, Patrice Verdier possible target group : Problems with the description of MET distributions in the data are commonplace, e.g. in NP physics analyses (and Top) that deal with large fake missing ET. The smearing procedures used in this context are often completely bogus. In particular, there is no understanding of contributions from unclustered energy. One or two of the large number of students in NP and Top should study this issue. It is important for their analyses. Uncorrected MET comparison : pass1 vs pass2 (= without/with cal_t42) =================================================================== manpower : 1 Ph.D/Professor timescale : 1 month contacts : Sophie Trincaz-Duvoid, Patrice Verdier possible target group : Again, this is of particular importance for analyses that deal with fake missing ET (e.g. in the NP group). We know that hot cell killing and to a lesser extent T42 improve missing ET in pass2. Effect of p17 calorimeter calibration on uncorrected MET ======================================================== manpower : 1 Ph.D/Professor timescale : 1-3 month contacts : Ursula Bassler, Jan Stark, Sophie Trincaz- Duvoid, Patrice Verdier possible target group : This is particularly relevant for analyses with fake missing ET in events that have a lot of EM activity, e.g. electrons from Z -> e e. The Top dielectron channel comes to mind. But jets also have an EM component ... Detailed studies on missingET corrections in the d0correct framework ==================================================================== manpower : 1 Ph.D/1 postdoc timescale : 3 month contacts : Frederic Deliot (d0correct), Emmanuel Busato (jet) Raimund Stroehmer (muon), Jan Stark (EM), Patrice Verdier (MET) possible target group : This is most important for analyses that rely on complex MET definitions that take into account many different objects (leptons, jets, ...). =============================================================================== JET-tasks: =============================================================================== automatise jet-id certification =============================== manpower: 1 Ph.D/postdoc timescale: 3-6 months contacts: Bernard, Amnon, Tobias Golling, James Heinmiller, Ariel Schwartzman in collaboration with e-flow possible target group : Almost everybody needs jets, right ? L1 jet-confirmation =================== L1 jet-confirmation implementation ---------------------------------- manpower: 1 Ph.D./postdoc timescale: 1 month. contacts: Bernard, Amnon, Tobias Golling, L1Cal-leader possible target group : Almost everybody needs jets, right ? L1 confirmation works very well, but is has many 'features' which can be improved: Treatment of soft and negative energy cells in particular the noisy remapped ICR cells, treatment of non-conical jets, etc. Will then need to reoptimize the cut with the new variable. L1 jet-confirmation - Real life L1 towers ----------------------------------------- manpower: 1 Ph.D./postdoc timescale: 2-3 months. contacts: Bernard, Amnon, Slava Shary, L1Cal-leader possible target group : Almost everybody needs jets, right ? L1 confirmation assumes all the L1 towers are identical and always OK. This is not the case. The performance of the towers (e.g. is it dead?) can be inferred from the few events that are taken in each run when there is no luminosity. This information can than be used to improve L1 confirmation. Data vs. Monte Carlo comparison - simulation tuning =================================================== manpower: 1 Professor/Ph.D./postdoc timescale: 6-9 months contacts: Bernard, Amnon. possible target group : Almost everybody needs jets, right ? Detailed study of cone jet implementation effects ================================================= manpower: 2 Ph.D./postdocs timescale: 3-6 months contacts: Bernard, Emmanuel Busato will start these studies but at least someone else is needed, QCD-group Study jet ID behavior in different events ========================================== manpower: 1 Professor/Ph.D./postdoc timescale: 2-4 months contacts: Bernard, Amnon - in collaboration with QCD =============================================================================== General tasks: =============================================================================== 22 Sept 2004 Title: Calorimeter Calibration implementation at L3 Advisers: Jon Hays, Jan Stark, Ursula Bassler Time estimate: 1.5 month Deadline: End of shutdown Description: The p17 version of D0Reco implements major improvement to the calibration of the calorimeter electronics, in particular pedestals, non-linearity correction and gains. These improvements should be propagated to the L3 trigger. The electronics calibration constants are updated regularly and are availiable for L3 as text-files. The mecanism to apply these text files at L3 and to provide proper book-keeping of the values used are established but need to be implemented. 22 Sept 2004 Title: Calorimeter phi-crack simulation Advisers: Marvin Jonson, Sarah Eno, Suichi Kunori Time estimate: 3 months Deadline: p17 simulation Description: Charge collection efficiencies have been established by Marvin for the calorimeter phi-cracks using a detailed and precise geometrical description. These should be implemented in the Geant simulation and tested against data. In addition the geometry used in Geant should be verified and documentation on the parameters used for the calorimeter simulation should be written. This job could be split in 2 parts. ------------------------------------------------------------------------------ Taken over: 22 Sept 2004 ==> 27 Sept 2004: Ioannis Katsanos Title: Determination of FPS Shower layer calibration coefficients Advisers: Abid Patwa, Yuan Hu Time estimate: 1 month Deadline: before reprocessing starts Description: We would like to include FPS-calibration and DB use in p17, which would give us a fair chance to include FPS in em-id and bring it up on a simliar level as CPS. A missing piece for this is the analysis of calibration data, that has been taken about a year ago. Previously Yuan Hu was working on this data, but his important implication in the PS-trigger prevented him to conclude his study. Finalizing his work would allow to establish proper values for FPS-Shower layers offline to be used in p17 and also benefit the ongoing trigger efforts for FPS.
