HQ in jets and b-tag

The flavor dependence of jet quenching is a powerful handle to discriminate models of parton energy loss in heavy ion collisions. While there is evidence for a strong energy loss of heavy quarks from single particle measurements, heavy flavor tagging of fully reconstructed jets has thus far not been achieved in heavy ion collisions. In this talk we demonstrate the capacity of CMS to identify...

HQ in jets and b-tag

A large part of the high-pt physics programme at the Tevatron and LHC colliders relies on the identification of jets originating from the fragmentation of b quarks. In my presentation I will discuss the salient features of the b-jet tagging algorithms developed to achieve this goal, and also discuss the methods that have been developed to calibrate the performance of these algorithms.

5. Coherence effects and broadening in medium-induced QCD radiation off a massive $q\bar q$ antenna

Studies of medium-induced QCD radiation usually rely on the calculation of single-gluon radiation spectrum off an energetic parton traversing an extended colored medium. Recently, the importance of interference effects between emitters in the medium has been explored. In this work we extend previous studies by calculating the single-gluon coherent spectrum off an antenna consisting of a...
