The dielectron cross section is measured with the ALICE detector as a function of the invariant mass $m_{\\rm{ee}}$ and the pair transverse momentum $p_{\\rm{T,ee}}$ in the ranges $m_{\\rm{ee}}$ < 3.5 GeV/$c^{2}$ and $p_{\\rm{T,ee}}$ < 8.0 GeV/$c^{2}$, in both collision systems. In proton-proton collisions, the charm and beauty cross sections are determined at midrapidity from a fit to the data with two different event generators. This complements the existing dielectron measurements performed at $\\sqrt{s}$ = 7 and 13 TeV. The slope of the $\\sqrt{s}$ dependence of the three measurements is described by FONLL calculations. The dielectron cross section measured in proton-lead collisions is in agreement, within the current precision, with the expected dielectron production without any nuclear matter effects for $\\rm{e}^{+}\\rm{e}^{-}$ pairs from open heavy-flavor hadron decays. For the first time at LHC energies, the dielectron production in proton-lead and proton-proton collisions are directly compared at the same $\\sqrt{s_{\\rm{NN}}}$ via the dielectron nuclear modification factor $R_{\\rm{pPb}}$. The measurements are compared to model calculations including cold nuclear matter effects, or additional sources of dielectrons from thermal radiation.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.98625.v1/t1","@type":"Dataset","description":"Inclusive $e^+e^-$ cross section in pp collisions at $\\sqrt{s}$ = 5.02 TeV as a function of $m_{\\rm ee}$.
