- Generalized z-Scaling and pp Collisions at RHIC Mikhail Tokarev Imrich Zborovský Física, Astronomía y Matemáticas Proton Scaling High energy Multiplicity Inclusive spectra New generalization of the z-scaling in inclusive particle production is proposed. The scaling variable z isexpressed in terms of the momentum fractions x1 and x2 of the incoming protons. Explicit dependence of z onthe momentum fractions ya and yb of the scattered and recoil constituents carried by the inclusive particle andrecoil object is included. The scaling function y(z) for charged and identified hadrons produced in proton-protoncollisions is constructed. The scheme allows unique description of data on inclusive cross sections of chargedhadrons, pions, kaons, antiprotons and lambdas produced at RHIC energies. The obtained results suggest thatthe z-scaling may be used as a tool for searching for new physics phenomena of particle production in hightransverse momentum and high multiplicity region at proton-proton colliders RHIC and LHC. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437540 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2C Vol.37
