Conclusion TkTOFTkTOF Good agreement between data and observation. One high mass candidates is slightly affecting the Rhadrons limit (but not so dramatic). TkOnlyTkOnly Good agreement between data and observation for loose selection and low mass. A couple of unpredicted candidates are observed for tight selection. Are being studied with more details by the group. Skims and DatasetsSkims and Datasets Lost many old samples and a couple of recent samples/files Due to a crash disk at Purdue Skim of May10ReReco need to be redone (SingleMu missing) Signals lost a fraction of the statistic (10-20% depending on the sample) MC Skim Done and published (see 2011 Twiki page) 10/06/ HSCP
