Abstract

Production of deuterons and antideuterons was studied by the NA49 experiment in the 23.5% most central Pb + Pb collisions at the top CERN Super Proton Synchroton (SPS) energy of root s(NN) = 17.3 GeV. Invariant yields for (d) over bar and d were measured as a function of centrality in the center-of-mass rapidity range -1.2 < y < -0.6. Results for (d) over bar (d) together with previously published (p) over bar (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
