Description

There is ongoing debate about the production mechanism of deuterons. Statistical production seems to describe the yields well, but seems unlikely on the short time scales of the collisions, as the binding energy of the deuteron is much smaller than the typical temperature of the producing hot fireball. The alternative is offered by coalescence. We propose that the two mechanisms could be distinguished by their predictions of the elliptic flow and test this hypothesis on simulations for the production at the LHC. While in a simplified approach where hadrons are produced from an enhanced blast-wave model we observe differences between the two models, a dynamical simulation with the help of vHLLE fluid-dynamical model with SMASH afterburner leads to predictions that are statistically not distinguishable.
