Title: DIFFRACTIVE ONIUM – NUCLEUS SCATTERING
AND GENEALOGY OF PARTON EVOLUTION
Abstract:
We present a partonic picture for diffractive onium – nucleus scattering from which the distribution of rapidity gap in a certain kinematic region can be deduced. This picture allows us to draw a parallel between diffractive dissociation and the genealogy of partonic evolution, the latter being essentially similar to a branching – diffusion process. In particular, we show that the rapidity gap distribution corresponds to the distribution of the splitting time of the most recent common ancestor
of the partons whose transverse momenta are larger than the nuclear saturation scale, when the scattering process is viewed in the restframe of the nucleus. Numerical calculations are also implemented to support the analytical predictions.
