Measurement of charged B meson production in pp collisions in Run 3

Description

Preliminary figures for the first measurement of the $\text{B}^\pm$ production cross section in pp collisions at $\sqrt{s} = 13.6$ TeV is reported, using data collected in 2023 and 2024. The measurement is performed at midrapidity (|$y$| < 0.5) and in the $1 < p_\text{T} < 23.5 \text{ GeV}/c$ interval, by fully reconstructing the decay chain $\text{B}^\pm \rightarrow \text{J}/\psi \text{K}^\pm$.
