Improved b-jet Energy Correction for H yields bottom quark bottom antiquark Searches at CDF.

摘要

We present a method for improving the b-jet energy resolution in order to improve the signal sensitivity in searches for particles decaying to a b quark and anti-b quark. A correction function is computed for individual jets, which combines information from the secondary vertex tagger, the offline tracking and standard calorimeter-based jet-energy reconstruction algorithm in order to provide a more accurate measurement of the true b-quark energy.
