The process e[sup +]e[sup -] --> [pi][sup +][pi][sup -][pi][sup 0][gamma] has been studied at a center-of-mass energy near the [Upsilon](4S) resonance using a 89.3 fb[sup -1] data sample collected with the BABAR detector at the PEP-II collider. From the measured 3[pi] mass spectrum the authors have obtained the products of branching fractions for the [omega] and [phi] mesons, B([omega] --> e[sup +]e[sup -])B([omega] --> 3[pi]) = (6.70 [+-] 0.06 [+-] 0.27) x 10[sup -5] and B([phi] --> e[sup +]e[sup -])B([phi] --> 3[pi]) = (4.30 [+-] 0.08 [+-] 0.21) x 10[sup -5], and evaluated the e[sup +]e[sup -] --> [pi][sup +][pi][sup -][pi][sup 0] cross section for the e[sup +]e[sup -] center-of-mass energy range 1.05 to 3.00 GeV. About 900 e[sup +]e[sup -] --> J/[psi][gamma] --> [pi][sup +][pi][sup -][pi][sup 0] events have been selected and the branching fraction B(J/[psi] --> [pi][sup +][pi][sup -][pi][sup 0]) = (2.18 [+-] 0.19)% has been measured.

We study the processes e{sup +}e{sup -} {yields} 3({pi}{sup +}{pi}{sup -}){gamma}, 2({pi}{sup +}{pi}{sup -}{pi}{sup 0}){gamma} and K{sup +}K{sup -} 2({pi}{sup +} {sup -}){gamma}, with the photon radiated from the initial state. About 20,000, 33,000 and 4,000 fully reconstructed events, respectively, have been selected from 232 fb{sup -1} of BABAR data. The invariant mass of the hadronic final state defines the effective e{sup +}e{sup -} center-of-mass energy, so that these data can be compared with the corresponding direct e{sup +}e{sup -} measurements. From the 3({pi}{sup +}{pi}{sup -}), 2({pi}{sup +}{pi}{sup -}{pi}{sup 0}) and K{sup +}K{sup -} 2({pi}{sup +}{pi}{sup -}) mass spectra, the cross sections for the processes e{sup +}e{sup -} {yields} 3({pi}{sup +}{sup -}), e{sup +}e{sup -} {yields} 2({pi}{sup +}{pi}{sup -}{pi}{sup 0}) and e{sup +}e{sup -} {yields} K{sup +}K{sup -} 2({pi}{sup +}{pi}{sup -}) are measured for center-of-mass energies from production threshold to 4.5 GeV. The uncertainty in the cross section measurement is typically 6-15%. We observe the J/{psi} in all these final states and measure the corresponding branching fractions.

A new state with invariant mass near 2.32 GeV=c[sup 2] has been observed by the BABAR Collaboration in the inclusive D[sub s][sup +] [pi][sup 0] mass distribution using 91 fb[sup -1] of e[sup +]e[sup -] annihilation data taken at the PEP-II asymmetric-energy storage ring at energies near 10.6 GeV. The new state is narrow, with an observed width that is consistent with the experimental resolution. This narrow width combined with the quantum numbers of the final state imply that the decay is isospin-violating. The state has natural spin-parity, and its low mass suggests a J[sup P] = 0[sup +] assignment.
