摘要:
We study the production of charged particles ( K+, K−, p, and p¯) in proton-proton ( pp) collisions at s=0.9TeV within the paciae model whose parameters we fix by comparing the yield of charged particles with experimental data from ALICE. We analyze the production of K−p and K+p¯ bound states with the paciae+dcpc model. Results of our work indicate that in pp collisions at s=0.9TeV the Λ(1405) and its antiparticle may be produced at almost the same rate if the Λ(1405) is a K−p bound state formed during the hadron rescattering period. The...
