We report inelastic interactions of protons at the center of mass energy s = 900 GeV, by using different event generators to study the forward-backward (FB) correlation in summed transverse momentum and multiplicity of produced charged particles. The transverse momentum, pT ≥ 100 MeV, and pseudorapidity, |η| < 2.5, have been employed for both the correlations. The simulation results are compared with the ATLAS experimental data, obtained with the same values of |η| and pT at s = 900 GeV. We also measure the jet and jet-like structure as a function of azimuthal distributions in the events relative to the highest transverse momentum particle. Three overlapping regions of pseudorapidity, |η| < 1.0, |η| < 2.0, and |η| < 2.5 are used with transverse momentum, pT > 500 MeV. For FB correlations, EPOS, and Sybill2.3c results are in a good agreement with the data as compared to the other models. Similarly, for the azimuthal distribution, EPOS-LHC, DPMJETIII, and Sibyll2.3c show good agreement with the data for full η region. In general, EPOS provides a better description of the data for both the quantities studied in this paper.

“…Only those events for which the beam tracks were properly reconstructed were used. This paper is a continuation of our hadron production study in the pC interaction at 31 GeV/c [12], 60 GeV/c [13] and 90 GeV/c [14]. The paper is organized as follows.…”

Hadron production measurements are important for the long baseline neutrino oscillation experiment as well as for the study of extensive air shower produced by cosmic rays. For precise measurements of the neutrinos flux prediction, K 0 S and Λ need to be considered. To this aim, the study of K 0 S and Λ in polar angle intervals of 0 to 300 mrad and 0 to 420 mrad, respectively, is carried out. Hadron production models, EPOS 1.99, EPOS-LHC and QGSJETII-04, are used to simulate the particles with proton-carbon interactions at 31 GeV/c. The models predictions are compared with the measurements of the NA61/SHINE experiment based on the analysis of data collected in 2009 with a carbon target. None of the models completely describe the experimental data over the entire range of momentum and angular intervals. EPOS 1.99 and EPOS-LHC give a good description of the data for both strange particles except at 0 < θ < 40 mrad for Λ, where the models overestimate. The QGSJETII-04 model overestimates the yield of the strange hadrons around the peak of the distribution, primarily at low angular intervals. Generally, all models are in excellent agreement at high momentum values of the distributions.
