Abstract

We present measurements of the inclusive production of antideuterons in e^+e^− annihilation into hadrons at ≈10.58  GeV center-of-mass energy and in Υ(1S,2S,3S) decays. The results are obtained using data collected by the BABAR detector at the PEP-II electron-positron collider. Assuming a fireball spectral shape for the emitted antideuteron momentum, we find B(Υ(1S)→d[bar]X)=(2.81±0.49(stat)^(+0.20)_(−0.24)(syst))×10^(−5), B(Υ(2S)→d[bar]X)=(2.64±0.11(stat)^(+0.26)(−0.21)(syst))×10^(−5), B(Υ(3S)→d[bar]X)=(2.33±0.15(stat)^(+0.31)_(−0.28)(syst))×10^(−5), and σ(e^+e^− →d[bar]X)=(9.63±0.41(stat)^(+1.17)_(−1.01)(syst)  fb.
