Measurement of bottomonia states in pp, pPb and PbPb collisionsat 2.76 TeV from CMS

The modification of jets in heavy ion collision at a center of mass energy of √sNN = 2.76 TeV was observed via various analyses carried out with Run I LHC data. In November 2015, LHC delivered the Run II phase lead-lead beams at 5.02 TeV and proton-proton beams at the same energy for reference. The...

Sumario:The modification of jets in heavy ion collision at a center of mass energy of √sNN = 2.76 TeV was observed via various analyses carried out with Run I LHC data. In November 2015, LHC delivered the Run II phase lead-lead beams at 5.02 TeV and proton-proton beams at the same energy for reference. The high luminosity PbPb data, more than twice of the previous run, provided an opportunity for elaborate studies based on high-pt probes. This presentation discusses the development of jet finding algorithms and jet observables, including the production rates, fragmentation patterns, and flavor dependence, published by CMS, ALICE and ATLAS collaborations. The results from 2.76 TeV data are briefly reviewed, followed by a presentation of the most recent results from √sNN = 5.02 TeV.
