The measurement of the $p_{\\mathrm{T}}$ spectra of  (anti-)deuterons is done up to 8 GeV/$c$ in 0-10\\% centrality class and up to 6 GeV/$c$ in 10-20\\% and 20-40\\% centrality classes. The $v_{2}$ is measured in the 0.8 $<$ $p_{\\mathrm{T}}$ $< $5 GeV/$c$ interval and in six different centrality intervals (0-5\\%, 5-10\\%, 10-20\\%, 20-30\\%, 30-40\\% and 40-50\\%) using the scalar product technique. Measured \\pio$^{\\pm}$, K$^{\\pm}$  and p+$\\overline{\\mathrm{p}}$ transverse-momentum spectra and $v_{2}$ are used to predict the deuteron $p_{\\mathrm{T}}$ spectra and $v_{2}$ within the Blast-Wave model. The predictions are able to reproduce the $v_{2}$ coefficient in the measured $p_{\\mathrm{T}}$ range and the transverse-momentum spectra for $p_{\\mathrm{T}}$ $>$ 1.8 GeV/$c$ within the experimental uncertainties. The measurement of the coalescence parameter $B_2$ is performed, showing a $p_{\\mathrm{T}}$ dependence in contrast with the simplest coalescence model, which fails to reproduce also the measured $v_{2}$ coefficient. In addition, the coalescence parameter $B_2$  and the elliptic flow coefficient in the 20-40\\% centrality interval are compared  with the  AMPT model which is able, in its version without string melting, to reproduce the measured $v_{2}$($p_{\\mathrm{T}}$) and the $B_2$($p_{\\mathrm{T}}$) trend.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.78549.v1/t1","@type":"Dataset","description":"Deuteron $p_{\\mathrm T}$ spectra for $p_{\\mathrm T} > $ 4.4 GeV/$c$.
