  Incoherent and dissociative J/$\psi$ photoproduction is sensitive to
fluctuations of the gluonic structure of the target. Thus, the measurement of
J/$\psi$ photoproduction of the colliding hadron sheds light on the initial
state of QCD and provides important constraints on the initial conditions used
in hydrodynamical models of heavy-ion collisions. The first measurement of the
transverse momentum dependence of both coherent and incoherent J/$\psi$
photoproduction in ultraperipheral Pb-Pb collisions at midrapidity is
presented. These new results provide, for the first time, a clear indication of
subnucleonic fluctuations of the lead target. We also present the new
measurement of dissociative J/$\psi$ photoproduction cross section as a
function of energy, in p-Pb collisions at forward rapidity. Dissociative
results do not show any indication of saturation and agree with previous data.
