  1. BHbb and BHuu Using Version 12 Training Monica Dunford FTK Monthly Meeting February 21, 2007

  2. Summary of Cuts • Studying WH->bb and WH->uu samples • For all samples, the following are applied • -1.0 < Cot() < 1.0 • -0.3 < curvature(GeV-1) < 0.3 • No cuts on truth track association

  3. Athena v10 FTK Results • Reprocessed Meena’s v10 samples • Number of tracks is much improved • Not much improvement in bb vs. uu impact parameter • Remainder of slides focuses on v12

  4. Athena v12 Data Sets • Using CSC Digitization processing • misal1_csc11.005850.WH120bb_pythia.digit.RDO.v12003103 • misal1_csc11.005851.WH120uu_pythia.digit.RDO.v12003103 • Have approximately 48,000 WHbb events and 32,000 WHuu events currently processed • Currently running WHbb and WHuu samples with TRT disabled in iPat • Will be done in a few days

  5. Athena v12 Number of Tracks • Fewer FTK tracks expected due to incomplete training

  6. WHbb Impact Parameter • New training has removed ‘features’ in v10 FTK distribution • Better agreement with iPat distribution • Test this against iPat with no TRT

  7. bb and uu Discrimination • FTK’s impact resolution is worse than iPat, especially in WHuu FTK iPat

  8. iPat Differences Between v10 and v12 • iPat Impact parameter resolution has worsen • But discrimination in v12 looks better with higher statistics (compared to last week)

  9. iPat and FTK Differences • FTK’s Pt vs. Impact distribution much different than iPat and truth FTK WHbb iPat WHbb Truth track distr. looks similar to iPat iPat WHuu FTK WHuu

  10. iPat and FTK Differences • Impact parameters distribution for two Pt ranges FTK WHbb iPat WHbb FTK WHuu iPat WHuu

  11. Next Ideas • Associate tracks to jets • Promised code from Meena • Compare FTK to iPat with no TRT • Jobs are currently running • Compare offline b-tagging algorithms between FTK and iPat
