\pt-differential inclusive \psis production cross section at midrapidity in \pp collisions at \thirteen. Statistical and systematic uncertainties are shown as error bars and boxes, respectively, and data points are plotted according to the Lafferty–Wyatt prescription . The data points for the inclusive production are obtained by summing the published prompt and non-prompt measurements . The statistical and systematic uncertainties are combined in quadrature. Uncertainties related to integrated luminosity are not shown.
