Abstract
We discuss a model which gives a ‘global’ description of the wide variety of high-energy elastic and diffractive data that are presently available, particularly from the LHC experiments. The model is based on only one pomeron pole, but includes multi-pomeron interactions. Significantly, the LHC measurements require that the model includes the transverse momentum dependence of the intermediate partons as a function of their rapidity, which results in a rapidity (or energy) dependence of the multi-pomeron vertices.
Highlights
Since this Workshop is in memory of Aliosha Kaidalov, it is appropriate to list some of his pioneering contributions to the understanding of Diffractive processes in high energy hadron interactions
One of the main puzzles, in the data sets, is that the diffractive dissociation cross sections observed at the LHC are smaller than expected from conventional Reggeon Field Theory (RFT) extrapolations of lower energy collider data
We have discussed a model [13] in which all the high-energy diffractive data may simultaneously be described within the Regge Field Theoretic framework based on only one pomeron pole
Summary
Since this Workshop is in memory of Aliosha Kaidalov, it is appropriate to list some of his pioneering contributions to the understanding of Diffractive processes in high energy hadron interactions. (b) The experimental information on low-mass dissociation is a puzzle in that the cross section σDlowMX goes from about 2 − 3 mb at the CERN-ISR energy of 62.5 GeV to only 2.6 ± 2.2 mb at 7 TeV at the LHC [17].
