$\pt$-differential production cross section of $\mathrm{B^0}$ mesons at midrapidity ($|y|< 0.5$) at the centre-of-mass energy of $\sqrt{s}=13.6$ $\mathrm{TeV}$ compared with measurements of the production cross section of $\mathrm{B^+}$ mesons performed at $\sqrt{s}=13$ $\mathrm{TeV}$ by the CMS Collaboration at midrapidity and by the LHCb Collaboration at forward rapidities. The FONLL calculations for the corresponding $\pt$ and rapidity intervals are also shown as filled boxes.
