Description
The production of deuterons in pp collisions at $\sqrt{s}=$ 13 TeV is simulated on an event-by-event basis using a coalescence afterburner based on a state-of-the-art Wigner-function formalism, and EPOS 3 and PYTHIA 8.3 as event generators. The nucleon-emitting source is modelled such to reproduce the $m_{\rm T}$-dependence of the source size measured by ALICE using femtoscopy. For the first time, the results of this model show that using a realistic wavefunction for deuterons, namely Argonne $v_{18}$, it is possible to reproduce the measured deuteron spectra with no free parameters.
