An Introduction to Pomerons
This talk is an attempt to clarify for experimentalists what do we (theorists) mean when we are saying “Pomeron”. I hope, that in this talk they will find answers to such questions as what is Pomeron, what we have learned about Pomeron both experimentally and theoretically, what is the correct strategy to study Pomeron experimentally and etc. I also hope that this talk could be used as a guide ...
متن کاملFluctuating pulled fronts & Pomerons
I give a physical discussion of the influence of particle number fluctuations on the high energy evolution in QCD. I emphasize the event–by–event description and the correspondence with the problem of ‘fluctuating pulled fronts’ in statistical physics. I show that the correlations generated by fluctuations reduce the phase–space for BFKL evolution up to saturation. Because of that, the evolutio...
متن کاملSoft and hard pomerons
Regge theory provides an excellent description of small-x structurefunction data from Q = 0 up to the highest available values. The large-Q data should also be described by perturbative QCD: the two descriptions must agree in the region where they overlap. However, at present there is a serious lack in our understanding of how to apply perturbative QCD at small x. The usual lowestorder or next-...
متن کاملSoft Physics – Three Pomerons?
A model of a three Pomeron contribution to high energy elastic pp and p̄p scattering is proposed. The data are well described for all momenta (0.01 ≤ |t| ≤ 14. GeV 2) and energies (8. ≤ √s ≤ 1800. GeV ) (χ2/d.o.f. = 2.60). The model predicts the appearance of two dips in the differential cross-section which will be measured at LHC. The parameters of the Pomeron trajectories are: α(0)P1 = 1.058, ...
متن کاملDo We Need Two Pomerons ?
We show that one single Pomeron compatible with the Froissart limit, can account for all the present HERA data.
