380pre2 details:

  • 24-June-2010 (K.Kovitanggoon) Jets: noticeable change on PF jets.
  • 15-June-2010 (A. Vartak) Tracking POG: The beamspot information used to generate events is inconsistent with the beamspot information used in the global tag for reconstruction. Consequently the tracking performance shows considerable discrepancy when compared to 380pre1.

  • 15-June-2010 (D.Wang) MET POG: for tcMET, there are discrepancies due to an incorrect beam spot in the 380p2 sample. This causes good tracks to fail the d0 requirement, and not be included in the tcmet correction, leading to a discrepancy in the sumet

  • 13-June-2010 (A.Giammanco) Tracker DPG: number of pixel hits per tracks shows a migration from multiplicity 2 to 0; being followed up by Tracking experts. Update: understood as coming from different beam spot (see Tracking POG comment, 15-June-2010) affecting acceptance. Fixed in pre4.

  • 14-June-2010 (A.Perrotta) Muon POG: Several failures observed, some of them already in pre1:
    • Lower fake rate of L2 muons in the endcaps (good) but also lower L1/L2 efficiency in JPsi CMS.RelVal sample (low pt muons): also in 380pre1
    • Inefficiency at eta~1.3 in the TRACKER component of the reco muons. It propagates also to Global Muon. (Both MC and STARTUP: it does not depend on conditions). NOT IN FASTSIM.
    • Higher fake rate of forward TRACKER tracks in multiparticle events (TTbar, etc.). NOT IN FASTSIM.
    • All L2/STA muons updated at vertex fail in reconstructing the dxy component of the impact par.There is effect on the Phi/Pt reconstruction and resolution of higher pt L2/STA muons. NOT IN FASTSIM
    • ISOLATION: lower number of charged tracks and average charged momenta in the isolation cone. Big differences in all TRACKER based isolation variables (to be checked), NOT IN FASTSIM, where all isolation distributions are still consistent with previous releases

380pre4 details:

380pre5 details:

  • 29-June-2010 (A.Perrotta) Muon POG: tracking related failures solved since pre2 (already in pre4); other issues are still there:
    • Lower fake rate of L2 muons in the endcaps (good) but also lower L1/L2 efficiency in JPsi CMS.RelVal sample (low pt muons)
    • StandAlone muons and, in particular, STA-SET muons, have worse resolutions before updating at vertex than in 370 in the samples where there are muons with larger momenta.

380pre8 details:

  • 13-July-2010 (A.Perrotta) Muon POG: same as since 380pre5
  • 09-Aug-2010 (T. Cox) Muon CSC: note that this is first release with rechit timing changed so that in-time muons have rechit time 0 rather than a raw sca peak position (approx. 4) as in all earlier releases. We need to change the histogram binning to match.

380 details:

  • 29-July-2010 (A.Perrotta) Muon POG: pending issues since 380pre5 have been fully understood, and the muon POG validation flag can finally turn to green:
    • the L1 lower efficiency results from a more realistic description of the ghost cancellation windows in the emulator, thus it has to be accepted as an improved description of the true detector behavior;
    • the worsening of resolution of the StandAlone (normal and SET) high pt muons is due to a change in the position of the BeamSpot in the MC: it has to be fixed, but it is not critical, as it does not affect the global reconstruction.

381 details:

  • 19-August-2010 (A. Vartak) Tracking POG: The fake rate v/s dz plot shows large discrepancy between 380 and 381. This can be attributed to the change in beamspot conditions in 381 as compared to 380
  • 19-August-2010 (A.Giammanco) Tracker DPG: change in pixel charge distributions attributed to the change in beamspot, too.
  • 25-August-2010 (N.Marinelli) Egamma: There are discrepancies w.r.t. 380 in the photon eta distribution in single particles and in the z coordinate of primary vertex inferred from conversion tracks. This is certainly due to the different beam spot conditions.

382 details

  • 7-September-2010 (J. Santaolalla) descrepancies eventually explained by Nicola Amapane
