Extracting the Pomeron-Pomeron Cross Section from Diffractive Mass Spectra

چکیده

We have calculated the mass distribution (dσ/dMX ) as observed by UA8 Collaboration in the inclusive reaction pp̄ → pXp̄ at √s = 630GeV , using the Interacting Gluon Model (IGM) with Double Pomeron Exchange (DPE) included. The only new parameter is the IP -IP cross section, which we can extract from fitting experimental data. We compare our results with the values obtained in the UA8 study. Assuming a constant Pomeron-Pomeron total cross section (σIP IP = 1mb), we make predictions for dσ/dMX at Tevatron and LHC energies.

The extraction of the bare triple - Pomeron vertex ; a crucial ingredient for diffraction

The triple-Pomeron coupling lies at the heart of the predictions for high energy diffractive processes. We explain why the existing determinations, which use single-particle inclusive hadronic data a+ b → a+Y , underestimate the value of the bare coupling, due to the neglect of soft rescattering which populates the rapidity gaps. We describe how data for the process γ+ p → J/ψ+Y can be used to ...

Diffractive Dis from the Generalized Bfkl Pomeron. Predictions for Hera

We present microscopic QCD calculation of the cross section of diffractive DIS and of the partonic structure of the pomeron from the dipole approach to the generalized BFKL pomeron. We show that the pomeron can not be treated as a particle with uniquely defined structure function and flux in the proton. We find strong factorization breaking which can approximately be described by the two-compon...

Unitarized model of hadronic diffractive dissociation.

It is shown that in a supercritical pomeron model the contribution of the tirple-pomeron diagrams violates the unitarity bound for cross-section even with account of the multiple pomeron exchanges between the initial hadrons. Asymptotic behaviour of the single diffractive dissoci-ation cross-section is calculated in the approximation where every pomeron in the 3P-diagram is eikonalized as well ...

Deep Inelastic Electron–Pomeron Scattering at HERA

The idea that the pomeron has partonic structure similar to any other hadron has been given strong support by recent measurements of the diffractive structure function at HERA. We present a detailed theoretical analysis of the diffractive structure function under the assumption that the diffractive cross section can be factorized into a pomeron emission factor and the deep inelastic scattering ...

Soft diffraction at the LHC: a partonic interpretation

We present a ‘new generation’ model for high energy proton-proton ‘soft’ interactions. It allows for a full set of multi-Pomeron vertices, as well as including multichannel eikonal scattering. It describes the behaviour of the proton-proton total, σtot, and elastic dσel/dt, cross sections together with those for low and high-mass proton dissociation. Although the model contains a comprehensive ...
