Baryon number transportation over full rapidity space in
pp
collisions at energies available at the CERN Large Hadron Collide
Banajit Barman, Nur Hussain, Buddhadeb Bhattacharjee The estimation of the antibaryon to baryon ratio is considered to be a useful tool for studying baryon number transport in pp, pA, and AA collisions. For this paper, the event generator with various tunes is used to measure the Λ¯/Λ ratio as a function of rapidity (y), transverse momentum (pT ), and multiplicity within both ALICE and LHCb acceptances. The results obtained using various Monte Carlo data for pp collisions at s=0.9 and 7 TeV are compared with the experimentally measured values of Λ¯/Λ ratio of ALICE and LHCb experiments. Out of the various studied tunes of 8.3, the string junction model is found to be the most successful to describe 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 recognized.
