W boson studies in pPb and PbPb collisions with CMS
The electroweak W bosons do not participate in the strong interaction, and thus constitute clean probes of the initial state of nuclear collisions. They provide a unique constraint on the nuclear parton distributions, in particular on the antiquarks from the sea. A first analysis of PbPb data has confirmed the medium-blind characteristic of the electroweak bosons. With the new pPb data, collect...
متن کاملCharmonium production measured in PbPb and pp collisions by CMS
The Compact Muon Solenoid (CMS) is fully equipped to measure hard probes in the di-muon decay channel in the high multiplicity environment of nucleus-nucleus collisions. Such probes are especially relevant for studying the quark-gluon plasma since they are produced at early times and propagate through the medium, mapping its evolution. CMS is able to distinguish non-prompt from prompt J/ψ in pp...

متن کاملFemtoscopy with Identified Hadrons in pp, pPb, and PbPb Collisions in CMS
Abstract: Short-range correlations of identified charged hadrons in pp ( √ s = 0.9, 2.76, and 7 TeV), pPb (sNN = 5.02 TeV), and peripheral PbPb collisions ( sNN = 2.76 TeV) are studied with the CMS detector at the LHC. Charged pions, kaons, and protons at low momentum and in laboratory pseudorapidity |η| < 1 are identified via their energy loss in the silicon tracker. The two-particle correlati...
متن کاملMeasurement of high-p[subscript T] azimuthal anisotropy in charged hadron production from 2.76 Tev PbPb collisions at CMS
Measurements of the azimuthal anisotropy of charged hadrons are presented for PbPb collisions at √ sNN = 2.76 TeV over an extended transverse momentum range. The data were collected with the CMS detector at the LHC. The anisotropy parameter (v2) is extracted up to a significantly higher pT region than previously achieved, by correlating charged tracks with respect to the event plane reconstruct...
