Özet
A systematic study of the factorization of long-range azimuthal two-particle correlations into a product of single-particle anisotropies is presented as a function of and of both particles and as a function of the particle multiplicity in PbPb and collisions. The data were taken with the CMS detector for PbPb collisions at TeV and collisions at TeV, covering a very wide range of multiplicity. Factorization is observed to be broken as a function of both particle and . When measured with particles of different , the magnitude of the factorization breakdown for the second Fourier harmonic reaches 20% for very central PbPb collisions but decreases rapidly as the multiplicity decreases. The data are consistent with viscous hydrodynamic predictions, which suggest that the effect of factorization breaking is mainly sensitive to the initial-state conditions rather than to the transport properties (e.g., shear viscosity …
