| contents | The estimation of anti-baryon to baryon ratio is considered to be a useful tool for studying baryon number transport in pp, pA and AA collisions. For this study, the Pythia event generator with various tunes is used to measure the ${\Anti-Lamda}$/$\Lamda$ ratio as a function of rapidity (y), transverse momentum (pT ), and multiplicity within both ALICE and LHCb acceptances. The results obtained using various MC data for pp collisions at \sqrt{s} = 7 TeV are compared with the experimentally measured values of ${\Anti-Lamda}$/$\Lamda$ ratio of ALICE and LHCb experiments. Out of the various studied tunes of Pythia 8.3, the string junction model is found to be the most successful in describing the experimentally observed results. Evidence of a considerable amount of baryon number transportation from the beam fragmentation to the ALICE and LHCb acceptances could be recognised. |
