Upper Limit of D0 Production in Central Pb-Pb Collisions at 158A GeV
NA49 Collaboration
Abstract
Results are presented from a search for the decays D0 -> Kmin piplus and D0bar -> Kplus pimin in a sample of 3.8x106 central Pb-Pb events collected with a beam energy of 158A GeV by NA49 at the CERN SPS. No signal is observed. An upper limit on D0 production is derived and compared to predictions from several models.
