Observation of e+e-→ρ+ρ- near s=10.58GeV
We report the first observation of e+e-→ρ+ρ-, in a data sample of 379fb-1 collected with the BABAR detector at the PEP-II e+e- storage ring at center-of-mass energies near s=10.58GeV. We measure a cross section of σ(e+e-→ρ+ρ-)=8.3±0.7(stat)±0.8(syst)fb within the range of |cos θ*|<0.8 and |co...
