Figure 1

$p_\mathrm{T}$-differential invariant production cross section of electrons from semileptonic heavy-flavour hadron decays in pp collisions at $\sqrt{s}=5.02$ TeV. The measurement is compared with the FONLL calculation . In the bottom panel, the ratios with respect to the central values of the FONLL calculation are shown. An additional 2.1\% normalisation uncertainty, due to the measurement of the minimum bias triggered cross section , is not shown in the results.
