Entwicklung von Objekt orientierten C++ Algorithmen zur b-Quark Identifikation
… events in the CMS detector. The new combined b-tag developed for ALEPH developed uses a combination of observables sensitive to the differences of b-hadron decays from other light quark hadron decays. The b-tag is based on the the ALEPH reconstruction algorithms for tracks and jets optimized for …

Sensitivity of the Top quark mass measurement with the CMS experiment at LHC using t-tbar multijet simulated events
… has been provided to reduce the S/B ratio. The b-tag is applied to provide a further S/B improvement. The selection is applied to the background sample and to the samples generated at different top quark masses. The top quark mass candidate is reconstructed for all those samples using a kinematic …

A Search For The Sm Higgs Boson In The Process Zhllbb In 4.1/fb Of Cdf Ii Data
… separately optimized for each of our three b-tag categories.</p> <p>We find good agreement between the observed data and the predicted SM backgrounds.</p> <p>The neural network output for data is compared to the output for the expected SM background to set 95% confidence level upper limits on …

A search for the ttH (H → bb) channel at the Large Hadron Collider with the ATLAS detector using a matrix element method
… selected events based on their jet and b-tag multiplicities, signal rich regions are analyzed using the matrix element method. Resulting variables are then propagated to two parallel multivariate analyses utilizing Neural Networks and Boosted Decision Trees respectively. As no significant …

ATLAS Level-1 Jet Trigger Rates and study of the ATLAS discovery potential of the neutral MSSM Higgs bosons in b-jet decay channels
… rates from the QCD multi-jet processes, the b-tagging capability of the LVL2 trigger is essential for the Higgs discovery in these channels. Canonical ATLAS b-tag/mistag efficiencies are applied on reconstructed jets. Finally, 5-sigma discovery contours in the (tan(beta), mA) plane are derived.
