Low-mass dielectron measurements play an essential role in the study of theQuark-Gluon Plasma (QGP) created in ultra-relativistic heavy-ion collisions.They are produced in all stages of the collision and are not affected byfinal-state interactions. Thus, they provide a penetrating probe of the createdmedium. In the dielectron intermediate-mass region a measurement of the thermalradiation from the QGP gives information on the medium temperature. However, inthis region the main component of the dielectron continuum stems fromcorrelated semi-leptonic decays of charm and beauty hadrons. Therefore, it iscrucial to understand the heavy-flavour (HF) production in vacuum and to find away to separate this contribution from the thermal dielectron signal of theQGP. In this paper we will present the production of correlated $\rm e^+e^-$pairs in pp collisions at $\sqrt{s} = 7$ TeV with the expectations from knownhadronic sources as a function of $m_{\rm ee}$, $p_{\rm T,ee}$, and the pairdistance of closest approach to the primary vertex $\rm DCA_{ee}$. Theextraction of the ratio of inclusive photons to decay photons and the charm andbeauty cross sections from a fit of the data with different Monte-Carlogenerators are presented, providing insight into the mechanisms ofheavy-flavour production. In particular, we demonstrate how the $\rm DCA_{ee}$variable will allow prompt and non-prompt dielectron pairs to be separated andthus help to disentangle the contribution of thermal radiation from thecontribution of charm and beauty. Finally, we present the prospect of extendingthis analysis to proton-lead collisions.
