**Figure 1.**Coalescence parameter ${B}_{2}$, measured by ALICE collaboration in Pb+Pb collisions at $\sqrt{{s}_{NN}}=$ 2.76 TeV [1] (circles) is compared to the outcome of our hybrid (hydrodynamics + transport) approach calculation (lines) and to the same calculation without rescatterings, only with decays (dashed lines). Note that we do not apply coalescence model. Instead, we adopt the approach of [4], where deuterons are produced at particlization, similarly to hadrons, and rescatter in the hadronic stage. ${B}_{2}$ emerges automatically in this case from dividing deuteron over proton spectra, according to Equation (1).

**a**)—pions, (

**c**)—protons, (

**d**)—deuterons) in Pb+Pb collisions at $\sqrt{{s}_{NN}}=$ 2.76 TeV. Measurements by ALICE collaboration [1,11] (circles) are compared to our hybrid (hydrodynamics + transport) approach calculation (lines). Note that computing deuteron spectra is parameter-free and does not apply coalescence model (see text).
