Study of the e(+)e(-)->pi(+)pi(-)pi(0) process using initial state radiation with BABAR

Abstract:

The process e+ e- → π+ π- π0 γ has been studied at a center-of-mass energy near the Y(4S) resonance using a 89.3 fb-1 data sample collected with the BABAR detector at the PEP-II collider. From the measured 3π mass spectrum we have obtained the products of branching fractions for the ω and φ mesons, B(ω → e+ e-) B(ω → 3π) = (6.70 ± 0.06 ± 0.27) × 10 -5 and B(φ → e+e-)B(φ → 3π) = (4.30 ± 0.08 ± 0.21) × 10-5 and evaluated the e+ e- → π+ π- π0 cross section for the e+ e - center-of-mass energy ra...
