A new determination of the soft pomeron intercept

Precision RENORM Tensor-Pomeron Cross Sections

“…We emphasize that the tensor-Pomeron model predicts directly only to the total cross section, while the predicted σ el is calculated by an extrapolation of the global-fit [9] ratio of σ el /σ tot multiplied by the tensor-Pomeron σ tot and therefore carries the larger uncertainties of this ratio. Future measurements of both σ el and σ tot at √ s = 8 TeV and √ s = 13 TeV with reduced luminosity and extrapolation uncertainties are needed to clarify the current experimental status.…”

“…It should be emphasized that the tensor-Pomeron hypothesis predicts directly only the total cross section. As discussed above, the elastic cross section for √ s ≤ 1.8 TeV is obtained from the global fit [9], while for 1.8 < √ s ≤ 13 TeV we use an extrapolation of the global-fit ratio of σ el /σ tot , which is slowly varying with √ s, multiplied by σ tot . The total inelastic cross section is calculated as the difference between the total and the elastic cross sections.…”

“…[9], while for 1.8 < √ s ≤ 50 TeV we use an extrapolation of the global-fit ratio of σ el /σ tot , which is slowly varying with √ s, multiplied by σ tot . The total non-diffractive cross section is given by σ ND = (σ tot − σ el ) − (2σ SD + σ DD + σ CD ).…”

From integral to derivative dispersion relations

“…In order to check the consistences between the IDR and the EDDR in an specific practical example, we consider, as a framework, a Regge Parametrization for the scattering amplitude [7]. For pp andpp scattering this analytical model assumes nondegenerate contributions from the even (+) and odd (−) secondary reggeons (a 2 , f 2 and ρ, ω, respectively), together with a simple pole Pomeron contribution:…”

Diffractive hadroproduction of dijets andW’s at the Fermilab Tevatron collider and the Pomeron structure function

“…Single Pomeron exchange plus a few secondary Reggeon contributions are enough to describe a variety of hadronic reactions (see, for instance, [1] and references therein).…”
