Description
We show that the use of a collinearly BFKL kernel in the
NLA amplitude for the electroproduction of two light vector mesons
leads to a smooth behavior of the amplitude with the center-of-mass
energy, both for equal and strongly ordered photons' virtualities.
Moreover, the optimal values of the energy scales appearing in the
subleading terms turn out to be closer to the kinematical scales of
the process than in the approaches based on the use of an unimproved
kernel.
