| 英文摘要 | We present measurements of two-particle differential number correlation functions R-2 and transverse momentum correlation functions P-2, obtained from p-Pb collisions at 5.02 TeV and Pb-Pb collisions at 2.76 TeV. The results are obtained by using charged particles in the pseudorapidity range vertical bar eta vertical bar < 1.0 and transverse momentum range 0.2 < p(T) < 2.0 GeV/c as a function of pair separation in pseudorapidity, vertical bar Delta eta vertical bar, azimuthal angle Delta phi, and for several charged-particle multiplicity classes. Measurements are carried out for like-sign and unlike-sign charged-particle pairs separately and combined to obtain charge-independent and charge-dependent correlation functions. We study the evolution of the width of the near-side peak of these correlation functions with collision centrality. Additionally, we study Fourier decompositions of the correlators in Delta phi as a function of pair separation vertical bar Delta eta vertical bar. Significant differences in the dependence of their harmonic coefficients on multiplicity classes are found. These differences can be exploited, in theoretical models, to obtain further insight into charged-particle production and transport in heavy-ion collisions. Moreover, an upper limit of nonflow contributions to flow coefficients nu(n) measured in Pb-Pb collisions based on the relative strength of Fourier coefficients measured in p-Pb interactions is estimated. |
