title = "Antideuteron yield at the ags and coalescence implications",
abstract = "We present Experiment 864's measurement of invariant antideuteron yields in 11.5A GeV/c Au + Pt collisions. The analysis includes 250 × 106 triggers representing 14 × 109 10% central interactions sampled for events with high mass candidates. We find (1/2 πpt)d2N/dydpt = 3.5 ± 1.5(stat)−0.5+0.9(syst) × 10−8GeV−2c2 for 1.8 < y < 2.2, (pt) = 0.35 GeV/c (yc.m. = 1.6) and 3.7 ± 2.7(stat)−1.5+1.4(syst) × 10−8 GeV−2c2 for 1.4 < y < 1.8, (pt) = 0.26 GeV/c, and a coalescence parameter B2- of 4.1 ± 2.9(stat)−2.4+2.3(syst) × 10−3 GeV2c−3. Implications for coalescence and antimatter annihilation are discussed.",
