Abstract

The hybrid model hydjet++, which considers soft and hard processes, is employed for the analysis of dihadron angular correlations measured in Pb+Pb collisions at center-of-mass energy sNN=2.76 TeV. The model allows the study of both individual and mutual influence of lower flow harmonics, v2 and v3, on higher harmonics and dihadron angular correlations. It is shown that the typical structure called a ridge in dihadron angular correlations in a broad pseudorapidity range could appear just as the interplay of v2 and v3. Central, semi-central, and semi-peripheral collisions were investigated. Comparison of model results with the experimental data on dihadron angular correlations is presented for different centralities and transverse momenta pT.
