dc.description.abstract | The transverse momentum \(p_{\rm T}\) spectra and elliptic flow coefficient \(v_2\) of deuterons and anti-deuterons at mid-rapidity \(|y|<0.5\) are measured with the ALICE detector at the LHC in Pb-Pb collisions at \(\sqrt{s_{\rm NN}} = 2.76\) TeV. The measurement of the \(p_{\rm T}\) spectra of (anti-)deuterons is done up to 8 GeV/\).\) in 0-10% centrality class and up to GeV/\).\) in 10-20% and 20-40% centrality classes. The \(v_2\) is measured in the \(0.8 <p_{\rm T} <5\) GeV/\).\) 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 \(\pi^{\pm}\). K\).{\pm}\) and p+\).overline{\mathrm{p}}\) transverse-momentum spectra and \(v_2\) are used to predict the deuteron \(p_{\rm T}\) spectra and \(v_2\) within the Blast-Wave model. The predictions are able to reproduce the \(v_2\) coefficient in the measured \(p_{\rm T}\) range and the transverse-momentum spectra for \(p_{\rm T}>1.8\) GeV/\).\) within the experimental uncertainties. The measurement of the coalescence parameter \(B_2\) is performed, showing a \(p_{\rm T}\) 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 \(v_2\).\(p_{\rm T}\) and the \(B_2\).\(p_{\rm T}\) trend. | en_US |
