Abstract

We report inelastic interactions of protons at the center of mass energy 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 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.
