“…Our present observation that the three amplitude Model B results in considerably smaller S 2 values, implies that the presumed consistency between most of the published survival probability outputs Survival Probability (for details see Ref. [18]) should be carefully re-examined using more robust models.…”

Based on the calculation of survival probabilities, we suggest a procedure to assess the value of G 3P , the triple Pomeron 'bare' coupling constant, by comparing the large rapidity gap single high mass diffraction data in proton-proton scattering and J/Ψ photo and DIS production. For p-p scattering the calculation in a three amplitude rescattering eikonal model, predicts the survival probability to be an order of magnitude smaller than for the two amplitude case. The calculation of the survival probabilities for photo and DIS J/Ψ production are made in a dedicated model. In this process we show that, even though its survival probability is considerably larger than in p-p scattering, its value is below unity and cannot be neglected in the data analysis. We argue that, regardless of the uncertainties in the suggested procedures, the outcome is important, both with regards to a realistic estimate of G 3P , and the survival probabilities relevant to LHC experiments.

“…We will consider the results for single diffractive processes with 2B = 5.5 GeV −2 (slope of the electromagnetic proton form factor) and without N * excitation, which is relevant to a forward proton spectrometer (FPS) measurement. Thus, we have < |S| 2 [12], which also considers a multi-channel eikonal approach.…”

In this contribution results from a phenomenological analysis for the diffractive hadroproduction of heavy flavors at high energies are reported. Diffractive production of charm, bottom and top are calculated using the Regge factorization, taking into account recent experimental determination of the diffractive parton density functions in Pomeron by the H1 Collaboration at DESY-HERA. In addition, multiple-Pomeron corrections are considered through the rapidity gap survival probability factor. We give numerical predictions for single diffractive as well as double Pomeron exchange (DPE) cross sections, which agree with the available data for diffractive production of charm and beauty. We make estimates which could be compared to future measurements at the LHC.

In this paper we compare the prediction for high energy soft interactions in the model of N = 4 SYM, with the experimental data. It is shown that this model is able to describe the total, elastic and inelastic cross sections and the elastic slope with only three free parameters. However, the model failed to obtain the cross sections for diffractive production, which was close to the experimental data, giving small values for them. We believe that the theory of N = 4 SYM, of the order of 1/λ is needed to find the origin of large mass diffraction.
