Book Description
The authors present preliminary measurements of branching fractions of the b 2!s{bar s}s penguin-dominated decays B{sup ±} 2![phi]K{sup ±} and B° 2![phi]K° in a sample of approximately 89 million B{bar B} pairs collected by the BABAR detector at the PEP-II asymmetric-energy B-meson Factor at SLAC. They determine [Beta](B{sup ±} 2![phi]K{sup ±}) = (10.0{sub -0.8}{sup +0.9}(stat.) {+-} 0.5(syst.)) x 10−6 and [Beta](B° 2![phi]K°) = (7.6{sub -1.2}{sup +1.3}(stat.) {+-} 0.5(syst.)) x 10−6. Additionally, they measure the charge asymmetry [Alpha]{sub CP}(B{sup {+-}} 2![phi]K{sup {+-}}) = 0.039 {+-} 0.086(stat.) {+-} 0.011(syst.) and set an upper limit on the CKM- and color-suppressed decay B{sup {+-}} 2![phi][pi]{sup {+-}}, [Beta](B{sup {+-}} 2![phi][pi]{sup {+-}})

Book Description
The search for rare B decays and direct CF violation at BABAR is described. The following measurements (based on integrated luminosities ranging from 56.4 to 81.9 fb[sup -1]) are summarized: the inclusive branching fractions and direct CF asymmetries of B[sup+][yields] h[sup+]h[sup -]H[sup+] (h=[pi], K), the exclusive branching fractions of B[sup+][yields] K[sup+][pi][sup -][pi][sup+] (where significant signals are observed in the B[sup+][yields] K*[sup 0](892)[pi][sup+], B[sup+][yields] f[sub 0](98)K[sup+], B[sup+][yields][chi][sub c0]K[sup+], B[sup+][yields][bar D][sup 0][pi][sup+] and B[sup+][yields] higher K*[sup 0][pi][sup+] channels), the branching fractions of B[sup+][yields][rho][sup 0][rho][sup+] and B[sup+][yields][rho][sup 0] K*[sup+], and finally, the branching fractions, the longitudinal components, and the direct CF asymmetries in B[yields][phi]K*.

Book Description
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

Book Description
We present preliminary results of the measurement of branching fractions and CP violating asymmetries in B meson decays to [eta][prime]K and [phi]K*. We update also the results of the direct CP violation searches with BABAR in charmless hadronic B meson decays.

Book Description
We present measurements of the branching fractions, longitudinal polarization, and direct CP-violation asymmetries for the decays B →?°K*+ and B+ f0(980)K*+ with a sample of (467 ± 5) x 106 B{bar B} pairs collected with the BABAR detector at the PEP-II asymmetric-energy e+e− collider at the SLAC National Accelerator Laboratory. We observe B+ →?°K*+ with a significance of 5.3? and measure the branching fraction?(B+ →?°K*+) = (4.6 ± 1.0 ± 0.4) x 10−6, the longitudinal polarization f{sub L} = 0.78 ± 0.12 ± 0.03, and the CP-violation asymmetry A{sub CP} = 0.31 ± 0.13 ± 0.03. We observe B+ → f0(980)K*+ and measure the branching fraction?(B+ → f0(980)K*+) x?(f0(980) →?+?−) = (4.2 ± 0.6 ± 0.3) x 10−6 and the CP-violation asymmetry A{sub CP} = -0.15 ± 0.12 ± 0.03. The first uncertainty quoted is statistical and the second is systematic.

Book Description
I present the results of searches for B meson decays into two charmless mesons. I take into account final states made up of two pseudo-scalar (PP) or one pseudo-scalar and one vector (PV). The measurements use the data samples collected and analyzed by the B-factory experiments at the [Upsilon](4S) resonance energy: BABAR, Belle and CLEO.

Book Description
We present measurements of branching fractions and CP-violating asymmetries in B[sup 0][yields][rho][sup[+-]][pi][sup[-+]] and B[sup 0][yields][rho][sup -]K[sup+] decays. The results are obtained from a data sample of 88.9 x 10[sup 6][Upsilon](4S)[yields] B[bar B] decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. From a time-dependent maximum likelihood fit we measure the charge-averaged branching fractions[Beta](B[sup 0][yields][rho][sup[+-]][pi][sup[-+]])= (22.6[+-] 1.8 (stat)[+-] 2.2 (syst)) x 10[sup -6] and[Beta](B[sup 0][yields][rho][sup -]K[sup+])= (7.3[sub -1.2][sup+1.3][+-] 1.3) x 10[sup -6]; and the CP-violating charge asymmetries A[sub CP][sup[rho][pi]]= -0.18[+-] 0.08[+-] 0.03 and A[sub CP][sup[rho]K]= 0.28[+-] 0.17[+-] 0.08; the direct CP violation parameter C[sub[rho][pi]]= 0.36[+-] 0.18[+-] 0.04 and the mixing-induced CP violation parameter S[sub[rho][pi]]= 0.19[+-] 0.24[+-] 0.03; and the dilution parameters[Delta]C[sub[rho][pi]]= 0.28[sub -0.19][sup+0.18][+-] 0.04 and[Delta]S[sub[rho][pi]]= 0.15[+-] 0.25[+-] 0.03.
