“…[84][85][86], for a good description, it is sufficient to choose N D ¼ 2, with the common parametrization for the matrix Ω ik given in Ref. [88] and briefly summarized for the sake of completeness in Appendix C. For the single diffractive scattering, the exponent in the expression (17) should be understood as a matrix element between jppi and jpXi states [89,90]. If Φ 1 and Φ 2 are eigenvalues of Ω ik with eigenvalues Ω 1 and Ω 2 , then the matrix exp ð−Ωðb; sÞÞ reduces in this basis to a linear combination of factors approximately e −Ω a ðs;bÞ , in which the coefficients can be fixed by projecting the proton and diffractive states onto the eigenstates Φ 1 , Φ 2 of the scattering matrix.…”

In this paper, we discuss the single diffractive production of open heavy flavor mesons and nonprompt charmonia in pp collisions. Using the color dipole approach, we found that the single diffractive production constitutes 0.5%-2% of the inclusive production of the same mesons. In Tevatron kinematics, our theoretical results are in reasonable agreement with the available experimental data. In LHC kinematics, we found that the cross section is sufficiently large and could be accessed experimentally. We also analyzed the dependence on multiplicity of coproduced hadrons and found that it is significantly slower than that of inclusive production of the same heavy mesons.

A QCD motivated model for soft interactions at high energies

In this paper we develop an approach to soft scattering processes at high energies, which is based on two mechanisms: Good-Walker mechanism for low mass diffraction and multi-Pomeron interactions for high mass diffraction. The pricipal idea, that allows us to specify the theory for Pomeron interactions, is that the so called soft processes occur at rather short distances (r 2 ∝ 1/ < p t > 2 ∝ α ′ IP ≈ 0.01 GeV −2 ), where perturbative QCD is valid. The value of the Pomeron slope α ′ IP was obtained from the fit to experimental data. Using this theoretical approach we suggest a model that fits all soft data in the ISR-Tevatron energy range, the total, elastic, single and double diffractive cross sections, including t dependence of the differential elastic cross section, and the mass dependence of single diffraction. In this model we calculate the survival probability of diffractive Higgs production, and obtained a value for this observable, which is smaller than 1% at the LHC energy range.

“…Consider a IP vertex with an incoming hadron |h and outgoing diffractive system approximated [7] as a single state |D . The GW mechanism is based on the observation that these states do not diagonalize the 2×2 interaction matrix.…”

Dedicated to Andrzej Białas in honour of his 75th birthdayAn updated formulation of the soft Pomeron, in which s and t channel unitarity screenings are included, is reviewed. The consequent soft scattering features are explored. A summary of the cross-section outputs of the leading groups active in this research are presented including also the calculated values of the gap survival probabilities, which is relevant, mostly, to hard diffractive processes. A utilization of pQCD in soft Pomeron formulation based on Gribov's Reggeon calculus is applied in the GLM model. The output parameters are compatible with AdS/CFT correspondence. The interplay between Pomeron theory and its corresponding data analysis is discussed. LHC soft scattering data is quoted and compared with theoretical predictions. Its implications for the Pomeron model are discussed.
