$\pt$-differential production cross section of $\mathrm{B^0}$ mesons measured at midrapidity ($|y|< 0.5$) in pp collisions at $\sqrt{s}=13.6 \mathrm{TeV}$ compared with Catania, TAMU, EPOS4HQ, and AMPT models (left panel) and ratios of the data to the theoretical predictions, where the latter are integrated over the width of the experimental $\pt$ intervals. (right panel). Statistical uncertainties are depicted as vertical error bars, and systematic uncertainties as boxes. The systematic uncertainties related to normalisation are quoted separately as text.
