Considering a dilute-dense situation suitable for pA collisions, we compute
in the Color Glass Condensate the correlation between azimuthal asymmetries,
specifically the squared second Fourier coefficient $v_2^2$, and the total
multiplicity in the event. We also analyse the correlation between $v_2^2$ and
the mean squared transverse momentum of particles in the event. In both cases,
we find that the correlations are generally very small, consistent with the
observations. We also note an interesting sharp change in the value of $v_2^2$
and its correlations as a function of the width of the transverse momentum bin,
related with a change of the dominance of Bose and HBT quantum correlations.
