Quark-Parton Fusion and the Scaling of Hadron Production at the LHC

Abstract

Hadron production, including pions, kaons and antiprotons, in proton-proton collisions at an energy of 7 TeV at the ALICE facility has been studied. For the data analysis, a generalised parton model was used, which takes into account the interaction of two partons in colliding beams and the production of new particles. Considering the effects of parton fusion and compound state formation results in a scaling dependence of the hadron production cross sections of different species.
