dc.description.abstract | The transverse momentum (pT) spectra and
elliptic flow coefficient (v2) 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 √sNN = 2.76 TeV.
The measurement of the pT 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 v2 is
measured in the 0.8 < pT < 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
π±, K± and p+p transverse-momentum spectra and v2 are
used to predict the deuteron pT spectra and v2 within the
Blast-Wave model. The predictions are able to reproduce the
v2 coefficient in the measured pT range and the transversemomentum
spectra for pT > 1.8 GeV/c within the experimental
uncertainties. The measurement of the coalescence
parameter B2 is performed, showing a pT dependence in
contrast with the simplest coalescence model, which fails to
reproduce also the measured v2 coefficient. In addition, the
coalescence parameter B2 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 v2(pT) and the B2(pT) trend. | |
