Differential yields of \rhos as a function of transverse momentum in inelastic pp collisions at \rs. The statistical and systematic uncertainties are shown as bars and boxes, respectively. The results are compared with model calculations from PYTHIA 6 (Perugia 2011 tune) , PYTHIA 8.14 (Monash 2013 tune)  and PHOJET . The lower panel shows the model-to-data ratios and the the gray shaded region represents the sum in quadrature of the systematic and statistical uncertainties associated with the data.
