Abstract	Production of deuterons and antideuterons was studied by the NA49 experiment in the 23.5% most central Pb+Pb collisions at the top SPS energy of $\sqrt{s_{NN}}$=17.3 GeV. Invariant yields for $\bar{d}$ and $d$ were measured as a function of centrality in the center-of-mass rapidity range $-1.2<y<-0.6$. Results for $\bar{d}(d)$ together with previously published $\bar{p}(p)$ measurements are discussed in the context of the coalescence model. The coalescence parameters $B_2$ were deduced as a function of transverse momentum $p_t$ and collision centrality.

$noimgSummary of the data sets used in the analysis. The number of events employed are given together with the fraction of the total cross-section (in percent) and corresponding average number of wounded nucleons $\langle N_w \rangle$ per event derived from the VENUS model.$ $(Color online) a) $dE/dx$ versus $m^2$ for positively charged particles in the momentum interval $7<p<8$~\gevc. The dashed ellipse illustrates the region populated by deuterons; the PID upper-limit $dE/dx$ cut is indicated by the horizontal line. b) $m^2$-distributions for both charges around the $m^2_d$ position for momenta from 4 to 10~\gevc\ ($dE/dx$ PID cut for $d (\overline{d})$ was applied). The arrow indicates the nominal $m^2$ position for $d(\overline{d})$.$ $Mass-squared distributions of $\overline{d}$ for rapidity $-1.2<y<-0.6$ in several transverse momentum bins: a) $0<p_t<0.3$~\gevc, b) $0.3<p_t<0.45$~\gevc, c) $0.45<p_t<0.6$~\gevc. Solid lines represent fits of a sum of a Gaussian signal and an exponential background.$ Show more plots
