\pt-differential inclusive \psis production cross section at midrapidity in \pp collisions at \thirteen is compared with ALICE results at forward rapidity~ (left) and with the model calculations from ICEM~ and NRQCD~ (right). Both calculations include a non-prompt contribution from beauty-hadron decays via FONLL~. Data points are plotted according to the Lafferty–Wyatt prescription~. The lower panels show the ratios of the data points or model calculations to the power-law fit to the midrapidity data.
