Presented is a search for the rare hadronic B meson decay B0 -> eta phi. It is based on 86 x 10^6 BB pairs recorded by the BABAR experiment at the Stanford Linear Accelerator Center between 1999 and 2002. phi mesons are reconstructed in the channel phi -> K+ K-. eta mesons are reconstructed in the channels eta -> gamma gamma and eta -> pi+ pi- pi0. Signal events are identified by a candidate counting and a maximum-likelihood method. To ensure an unbiased measurement, the number of signal events is blinded throughout the analysis. Although no significant signal is found by either method, the maximum-likelihood method obtains a smaller statistical uncertainty. In this method, the branching fraction of the decay B0 -> eta phi is determined by the upper limit BR (B0 -> eta phi)

Using 383 million B{bar B} pairs from the BABAR data sample, they report results for branching fractions of six charged B-meson decay modes, where a charged kaon recoils against a charmless resonance decaying to K{bar K}* or [eta][pi][pi] final states with mass in the range (1.2-1.8) GeV/c2. They observe a significant enhancement at the low K{bar K}* invariant mass which is interpreted as B 2![eta](1475)K, find evidence for the decay B+ 2![eta](1295)K+, and place upper limits on the decays B+ 2![eta](1405)K+, B+ 2!f1(1285)K+, B+ 2!f1(1420)K+, and B+ 2![phi](1680)K+.

This volume is a unique report on the frontiers of subnuclear physics presented by global specialists in a clear and rigorous style.The question of Lattice QCD is presented by R D Kenway, and that of Quark-Gluon Plasma Physics by F Karsch. Quantum Field theory is discussed by R G Dijkgraff, and the status of Local Supersymmetry by M J Duff. Detailed analysis of Supersymmetry in Nuclei is made by F Iachello, and that of Inflation, Dark Matter and Dark Energy by E W Kolb. Compactified dimensions are outlined by I Antoniadis, Horizons in the quantization of the gravitational force by Nobel Laureate G 't Hooft, as also are Neutrino Oscillations by G Fogli and Fundamental Constants by H Fritzsch. The experimental data from BNL and Babar are presented by T W Ludlum and M A Giorgi, those from Fermilab and Hera by Parke and G Wolf. The status at CERN is given by L Maiani for the LHC and by W-D Schlatter for the non-LHC experiments. Highlights from Gran Sasso are presented by A Bettini. This volume also contains reports by a selected group of “new talents” on various topics in the field of subnuclear physics.The proceedings have been selected for coverage in:• Index to Scientific & Technical Proceedings® (ISTP® / ISI Proceedings)• Index to Scientific & Technical Proceedings (ISTP CDROM version / ISI Proceedings)• CC Proceedings — Engineering & Physical Sciences
