Abstract: | The transverse momentum (pTpTp_\mathrm{T} ) spectra and elliptic flow coefficient (v2v2v_{2}) of deuterons and anti-deuterons at mid-rapidity (|y|<0.5|y|<0.5|y|<0.5) are measured with the ALICE detector at the LHC in Pb-Pb collisions at sNN−−−√sNN\sqrt{s_{\mathrm {NN}}} = 2.76 TeV. The measurement of the pTpTp_\mathrm{T} spectra of (anti-)deuterons is done up to 8 GeV/c/c/c in 0-10% centrality class and up to 6 GeV/c/c/c in 10-20% and 20-40% centrality classes. The v2v2v_{2} is measured in the 0.8 < pTpTp_\mathrm{T} < < <~5 GeV/c/c/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 ππ\pi ±±^{\pm }, K±±^{\pm } and p+p¯¯¯p¯\overline{\mathrm {p}} transverse-momentum spectra and v2v2v_{2} are used to predict the deuteron pTpTp_\mathrm{T} spectra and v2v2v_{2} within the Blast-Wave model. The predictions are able to reproduce the v2v2v_{2} coefficient in the measured pTpTp_\mathrm{T} range and the transverse-momentum spectra for pTpTp_\mathrm{T} > 1.8 GeV/c/c/c within the experimental uncertainties. The measurement of the coalescence parameter B2B2B_2 is performed, showing a pTpTp_\mathrm{T} dependence in contrast with the simplest coalescence model, which fails to reproduce also the measured v2v2v_{2} coefficient. In addition, the coalescence parameter B2B2B_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 v2v2v_{2}(pTpTp_\mathrm{T} ) and the B2B2B_2(pTpTp_\mathrm{T} ) trend. |
