  Within the dense-dilute Color Glass Condensate approach, and using the
Golec-Biernat-Wuesthoff model for the dipole scattering amplitude, we calculate
$v_2^2$ as well as the correlations between $v_2^2$ and both the total
multiplicity and the mean transverse momentum of produced particles. We find
that the correlations are generally very small consistent with the
observations. We note an interesting sharp change in the value of $v^2_2$ as
well as of its correlations as a function of the width of the transverse
momentum bin. This crossover is associated with the change from Bose
enhancement dominance of the correlation for narrow bin to HBT dominated
correlations for larger bin width.
