Abstract |
We study the processes e(+)e(-) -> 2(pi(+)pi(-))pi(0)pi(0)pi(0)gamma and 2(pi(+)pi(-))pi(0)pi(0)eta gamma in which an energetic photon is radiated from the initial state. The data were collected with the BABAR detector at SLAC. About 14 000 and 4700 events, respectively, are selected from a data sample corresponding to an integrated luminosity of 469 fb(-1). The invariant mass of the hadronic final state defines the effective e(+)e(-) center-of-mass energy. The center-of-mass energies range from threshold to 4.5 GeV. From the mass spectra, the first ever measurements of the e(+)e(-) -> 2(pi(+)pi(-))pi(0)pi(0)pi(0) and the e(+)e(-) -> 2(pi(+)pi(-))pi(0)pi(0)eta cross sections are performed. The contributions from omega pi(+)pi(-)pi(0)pi(0), eta 2(pi(+)pi(-)), and other intermediate states are presented. We observe the J/psi and psi(2S) in most of these final states and measure the corresponding branching fractions, many of them for the first time. |

Abstract |
Using the initial-state radiation method, the e(+) e(- )-> KSKL cross section from 1.98 to 2.54 GeV is measured in a data sample of 469 fb(-1) collected with the BABAR detector. The results are used in conjunction with previous BABAR results for the e(+) e(-)-> K+K-, e(+) e(-) -> pi(+)pi(-), e(+) e(- )-> pi(+)pi(-)eta, and e(+)e (-)-> omega pi pi cross sections to investigate the nature of the resonance structure recently observed by the BESIII experiment in the e(+) e(-)-> K+K- cross section. |

Abstract |
We present a search for seven lepton-flavor-violating neutral charm meson decays of the type D-0 -> X(0)e(+/-)mu(-/+), where X-0 represents a pi(0), K-S(0), (K) over bar*(0), rho(0), phi, omega, or eta meson. The analysis is based on 468 fb(-1) of e(+)e(-) annihilation data collected at or close to the Upsilon(4S) resonance with the BABAR detector at the SLAC National Accelerator Laboratory. No significant signals are observed, and we establish 90% confidence level upper limits on the branching fractions in the range (5.0-22.5) x 10(-7). The limits are between 1 and 2 orders of magnitude more stringent than previous measurements. |

Abstract |
A search for the rare flavor-changing neutral current process B- -> Lambda(p) over bar nu(nu) over bar using data from the BABAR experiment has been performed. A total of 424 fb(-1) of e(+) e(-) collision data collected at the center-of-mass energy of the Upsilon(4S) resonance is used in this study, corresponding to a sample of (471 +/- 3) x 10(6) B (B) over bar pairs. Signal B- -> Lambda(p) over bar nu(nu) over bar candidates arc identified by fast fully reconstructing a B+ decay in one of many possible exclusive decays to hadronic final states, then examining detector activity that is not associated with this reconstructed B+ decay for evidence of a signal B- -> Lambda(p) over bar nu(nu) over bar decay. The data yield is found to be consistent with the expected background contribution under a null signal hypothesis, resulting in an upper limit of B(B- -> Lambda(p) over bar nu(nu) over bar) < 3.0 x 10(-5) at the 90% confidence level. |

Abstract |
The decay tau(-) -> K- K(S)v(tau) has been studied using 430 x 10(6) e(+) e(-) -> tau(+) tau(-) events produced at a center-of-mass energy around 10.6 GeV at the PEP-II collider and studied with the BABAR detector. The mass spectrum of the K- K-S system has been measured and the spectral function has been obtained. The measured branching fraction B(tau(-) -> K- K(S)v(tau)) = (0.739 +/- 0.011 (stat) +/- 0.020 (syst)) x 10(-3) is found to be in agreement with earlier measurements. |
