DOWNLOAD EBOOKOur results on two-particle angular correlations for charged particles produced in pp collisions at a center-of-mass energy of 13 TeV are presented. The data were taken with the CMS detector at the LHC and correspond to an integrated luminosity of about 270 nb-1. The correlations are studied over a broad range of pseudorapidity).

DOWNLOAD EBOOKAzimuthal dihadron correlations of charged particles have been measured in PbPb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV by the CMS collaboration, using data from the 2011 LHC heavy-ion run. The data set includes a sample of ultra-central (0-0.2% centrality) PbPb events collected using a trigger based on total transverse energy in the hadron forward calorimeters and the total multiplicity of pixel clusters in the silicon pixel tracker. A total of about 1.8 million ultra-central events were recorded, corresponding to an integrated luminosity of 120 inverse microbarns. The observed correlations in ultra-central PbPb events are expected to be particularly sensitive to initial-state fluctuations. The single-particle anisotropy Fourier harmonics, from $v_2$ to $v_6$, are extracted as a function of particle transverse momentum. At higher transverse momentum, the $v_2$ harmonic becomes significantly smaller than the higher-order $v_n$ (n greater than or equal to 3). The pt-averaged $v_2$ and $v_3$ are found to be equal within 2%, while higher-order $v_n$ decrease as n increases. The breakdown of factorization of dihadron correlations into single-particle azimuthal anisotropies is observed. This effect is found to be most prominent in the ultra-central PbPb collisions, where the initial-state fluctuations play a dominant role. As a result, a comparison of the factorization data to hydrodynamic predictions with event-by-event fluctuating initial conditions is also presented.

DOWNLOAD EBOOKMeasurements from the CMS experiment at the LHC of dihadron correlations for charged particles produced in PbPb collisions at a nucleon-nucleon centre-of-mass energy of 2.76 TeV are presented. The results are reported as a function of the particle transverse momenta (pt) and collision centrality over a broad range in relative pseudorapidity [Delta(eta)] and the full range of relative azimuthal angle [Delta(phi)]. The observed two-dimensional correlation structure in Delta(eta) and Delta(phi) is characterised by a narrow peak at (Delta(eta), Delta(phi)) approximately (0, 0) from jet-like correlations and a long-range structure that persists up to at least.

DOWNLOAD EBOOKWe present evidence for charge correlations of[ital B] mesons with charged particles produced in[ital p[anti p]] Collisions at 1.8 TeV. Such correlations are expected to arise from pious produced in the fragmentation chain and from[ital B][sup**] decays. We measure the efficiency and purity of this flavor tagging method for both charged and neutral[ital B] mesons. We apply these correlations to[ital B] mesons reconstructed in 110 pb[sup -1] of data collected with the CDF detector at the Fermilab Tevatron Collider.[ital B] mesons are either partially reconstructed, using the semileptonic decays[ital B][sup 0][yields][ital l][sup+][ital D][sup (*)-][ital X] and[ital B][sup+][yields][ital l][sup+][ital[anti D]X], or fully reconstructed, using the decay modes[ital B][sup 0][yields][ital J/[Psi]K[sup*0]] and[ital B][sup+][yields][ital J/[Psi]K[sup+]]. Application of this new flavor tagging method to neutral[ital B] mesons yields a measurement of the frequency of the oscillation[ital B][sup 0][yields][ital[anti B]][sup 0].
