Paramaterizations of inclusive cross sections for pion production in proton-proton collisions. II. Comparison to new data
arXiv:hep-ph/0701251 · doi:10.1103/PhysRevD.75.034001
Abstract
A set of new, precise data have recently been made available by the NA49 collaboration for charged pion production in proton-proton and proton-Carbon reactions at 158 GeV. The current paper compares this new data to five currently available arithmetic parameterizations. Although a precise fit is not expected, two of the parameterizations do not work very well but the other three are able to provide a moderately good, but not precise fit to the proton-proton data. The best two of these three parameterizations are scaled to the proton-Carbon data and again provide a moderately good, but not precise fit.
