Probing subnucleon scale fluctuations in ultraperipheral heavy ion collisions
We show that introducing subnucleon scale fluctuations constrained by HERA
diffractive production data significantly affects the incoherent
diffractive production cross section in ultraperipheral heavy ion
collisions. We find that the inclusion of the additional fluctuations increases
the ratio of the incoherent to the coherent cross section approximately by a
factor of , and modifies the transverse momentum spectra of the produced
at momenta larger than the scale that corresponds to the distance
scale of the subnucleonic fluctuations. We present predictions for
production in ultraperipheral heavy ion collisions at at the LHC and at RHIC.Comment: 9 pages, 8 figures. v2: small clarifications to the text, matches the
