Heavy Flavored Jet Modification at CMS

Jet Physics in CMS Heavy Ion Programme

In this note, we report on the study of jet+ jet, γ + jet and Z(→ μμ) + jet production in heavy ion collisions. In particular, we review the capability of the CMS detector to observe the energy losses of quarkand gluon-initiated jets in a dense QCD matter. 1 Jet quenching: jet + jet, γ + jet and Z + jet production Hard jet production is considered to be an efficient probe for formation of super...

Algorithms for b-Jet Identification at CMS

A comprehensive set of algorithms to identify jets originating from b-quarks has been developed within the CMS Collaboration. The fundamental properties of B-hadrons leading to observables which can be exploited for b-tagging are discussed and an overview of the basic concepts of the algorithms is given, followed by a comparison of their performance.

Search for heavy resonances at CMS

The search for new physics at the TeV scale is one of the major aspects of the CMS experimental program. This includes a myriad of theoretical models involving resonances that can decay to massive bosons, leptons or jets. An overview of such analyses is presented in this paper as well as the novel dedicated techniques related to the specificity of the event topologies. All analyses presented he...

Heavy Ion Physics with CMS at LHC

The Large Hadron Collider (LHC) plans to operate as a heavy ion collider for one month each year starting in 2007. LHC will be capable of accelerating a variety of ions up to beam energies of 7 TeV/charge. The design, peak and three-hour-fill-averaged luminosities are presented in Table 1 along with the maximum center of mass energy[1]. The Compact Muon Solenoid (CMS) [2] experiment is a genera...
