 The $p_{\rm T}$-differential invariant production cross section for electrons from semileptonicheavy-flavour hadron decays measured at mid-rapidity in pp collisions at $\sqrt{s} = 2.76$~TeV in comparison with FONLL pQCD calculations~ (upper panel), and the ratio of the data to the FONLL calculation (lower panel). Statistical and systematic uncertainties areshown as vertical bars and boxes, respectively.
