  The hybrid model HYDJET++, which combines soft and hard components, is
employed for the analysis of dihadron angular correlations measured in PbPb
collisions at center-of-mass energy sqrt(s_NN) = 2.76 TeV. The model allows for
study both individual contributions and mutual influence of lower flow
harmonics, v_2 and v_3, on higher harmonics and dihadron angular correlations.
It is shown that the typical structure called ridge in dihadron angular
correlations in a broad pseudorapidity range could appear just as interplay of
v_2 and v_3. 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 p_T.
