We employ a hybrid approach to describe the light nuclei production mechanism where the nucleons are assumed to be thermally produced, and are allowed to form light nuclei using a coalescence prescription. In this approach, we first fit transverse momentum (p&sub(T)) distribution of nucleons using hydro-inspired boost-invariant Blast-wave model. The extracted parameters are then used to describe the deuteron p&sub(T) spectra, along with two additional parameters that characterize the coalescence prescription employed in this study. We refer this combined approach as “thermo-coalescence model” and it is designed to study the deuteron production and describe the experimental measurements. In this work, we analyze the measured p&sub(T) distribution of protons and deuterons from Pb–Pb collisions at the ALICE Collaboration at the LHC. We also evaluate the p&sub(T) -integrated deuteron yields using this approach and compare with experimental measurements. A Bayesian inference framework is employed to determine the best-fit parameters of the thermo-coalescence model. Finally, we estimate the traditionally used experimental coalescence parameter (B&sub(A) ) within our framework in order to establish a connection between our model and the conventional coalescence approach commonly used to relate experimental data with theoretical descriptions of light nuclei production.
