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 TeV. The model allows the study of both individual and mutual influence of lower flow harmonics, and , 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 and . 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 .
