“…The KNO scaling was observed in pp andpp collisions up to energies available at ISR accelerator, √ s ≤ 62 GeV. Its violation at higher energies was predicted by the RFT specialists, see, e.g., [1,7,51]. The mechanism of the KNO violation within the Reggeon Field Theory is as follows.…”

“…The quark-gluon string model, formulated about 35 years ago [1], employs the 1/N series expansion of the amplitude of a process in QCD, where N is either the number of colors [4] or the number of flavors [5]. This method is also called topological expansion, because of emergence of diagrams of various topologies.…”

“…The Monte Carlo version of the QGSM [6] employs statistical weights, hadron structure functions and leading quark fragmentation functions obtained from the Regge approach in [1] to choose subprocesses of string production, to compute mass and momentum of strings and to simulate string decays, respectively. The hadron-hadron collision part of the model includes single and double diffraction subprocesses, antibaryon-baryon annihilation and elastic scattering.…”

Abstract. Proton-proton collisions at energies from √ s = 200 GeV up to √ s = 14 TeV are studied within the microscopic quark-gluon string model. The model is based on Gribov's Reggeon Field Theory accomplished by string phenomenology. Comparison with experimental data shows that QGSM describes well particle yields, rapidity-and transverse momentum spectra, rise of mean �p T � and forward-backward multiplicity correlations. The latter arise in QGSM because of the addition of various processes with different mean multiplicities. The model also indicates fulfillment of extended longitudinal scaling and violation of Koba-Nielsen-Olesen scaling at LHC. The origin of both features is traced to short-range particle correlations in the strings. Predictions are made for √ s = 14 TeV.

“…Other techniques, based on non-perturbative methods, should be utilized. The quark-gluon string model (QGSM) [1] and similar to it dual parton model (DPM) [2] is one of the possible approaches to solution of this very interesting and difficult problem. Both models are based on the Reggeon Field theory (RFT) [3].…”

Abstract. The microscopic Monte Carlo quark-gluon string model (QGSM) is employed to study particle production in ultrarelativistic proton-proton collisions. The model is based on Reggeon Field theory accomplished by string phenomenology. Various observables, including multiplicity, rapidity and transverse momentum spectra, short-range, long-range and femtoscopy correlations, are described quite well in a wide span of the collision energy. Predictions are made for pp collisions at √ s = 14 TeV.

The character of asymmetry between the spectra of Λc andΛc, obtained recently in the E781 experiment (FNAL) is discussed on the basis of the Quark Gluon String Model(QGSM). As it was shown in the description of the asymmetry between the spectra of leading and nonleading charmed mesons measured in Σ − − A interactions at pL= 340 GeV/c in the WA89 experiment in previous studies, the asymmetries between D − and D + meson spectra and between D − s and D + s meson spectra can be fitted by QGSM curves obtained with the same parameter of string fragmentation, a1=10, as well as the asymmetry between the D-meson spectra in π − A collisions at the E791 experiment. The forms of Λc/Λc asymmetry dependenses measured in Σ − A and p − A collisions at pL= 600 GeV/c in the E781 experiment are different. It is shown in the framework of QGSM that they depend on whether the diquarks of beam and target particles took part in charmed baryon formation or not. The QGSM results are compared with the calculations carried out by the other authors.
