The dielectron cross section in inelastic \pp collisions at $\sqrts = 13\TeV$ as a function of invariant mass (left) and of pair transverse momentum in different mass intervals (right). The global scale uncertainty on the \pp luminosity (5\%) is not shown. The statistical and systematic uncertainties of the data are shown as vertical bars and boxes The expectation from the hadronic decay cocktail is shown as a band, and the bottom left plot shows the ratio data to cocktail together with the cocktail uncertainty. | ![](https://alice-publications.web.cern.ch/sites/default/files/papers/4291/Signal_cocktail_pt0_pythia-92055.png ) ![](https://alice-publications.web.cern.ch/sites/default/files/papers/4291/Signal_cocktail_pteespectra-92057.png ) |
