We have measured the branching fraction B, longitudinal polarization fraction f(L), and CP asymmetry coefficients A and S for B-0->rho(+)rho(-) decays with the Belle detector at the KEKB e(+)e(-) collider using 253 fb(-1) of data. We obtain B=[22.8 +/- 3.8(stat)(-2.6)(+2.3)(syst)]x10(-6), f(L)=0.941(-0.040)(+0.034)(stat)+/- 0.030(syst), A=0.00 +/- 0.30(stat)+/- 0.09(syst), and S=0.08 +/- 0.41(stat)+/- 0.09(syst). These values are used to constrain the Cabibbo-Kobayashi-Maskawa phase phi(2); the solution consistent with the standard model is phi(2)=(88 +/- 17)degrees or 59 degrees <phi 2 < 115 degrees at 90% C.L.

The old silicon vertex detector (SVD1) of the Belle detector, operating at the high-luminosity asymmetric energy e+e- collider KEKB, was replaced by an upgraded version (SVD2) in 2003. The new detector has modified geometry and redesigned readout electronics, providing a larger polar angle acceptance, better vertex resolution, improved radiation hardness and reduced dead time. The operation of the detector started successfully in October 2003. The basic concepts of the SVD2 design as well as its performance after 10 months of data taking are described in this paper.

We report the results of a search for D-0-D-0 mixing in D-0-> K(+)pi(-) decays based on 400 fb(-1) of data accumulated by the Belle detector at KEKB. Both assuming CP conservation and allowing for CP violation, we fit the decay-time distribution for the mixing parameters x(') and y('), as well as for the parameter R-D, the ratio of doubly Cabibbo-suppressed decays to Cabibbo-favored decays. The 95% confidence level region in the (x('2),y(')) plane is obtained using a frequentist method. Assuming CP conservation, we find x('2)< 0.72x10(-3) and -9.9x10(-3)< y(')< 6.8x10(-3) at the 95% confidence level; these are the most stringent constraints on the mixing parameters to date. The no-mixing point (0,0) has a confidence level of 3.9%. Assuming no mixing, we measure R-D=(0.377 +/- 0.008 +/- 0.005)%.

We describe a new pixel detector development project using a 0.15 mu m fully-depleted CMOS SOI (Silicon-On-Insulator) technology. Additional processing steps for creating substrate implants and contacts to form sensor and electrode connections were developed for this SOI process. A diode Test Element Group and several test chips have been fabricated and evaluated. The pixel detectors are successfully operated and first images are taken and sensibility to beta-rays is confirmed. Back gate effects on the top circuits are observed and discussed.

We report measurements of B meson decays to two kaons using 253 fb(-1) of data collected with the Belle detector at the KEKB energy-asymmetric e(+)e(-) collider. We find evidence for signals in B+->(K) over bar K-0(+) and B-0-> K-0(K) over bar (0) with significances of 3.0 sigma and 3.5 sigma, respectively. (Charge-conjugate modes are included.) The corresponding branching fractions are measured to be B(B+->(K) over bar K-0(+))=(1.0 +/- 0.4 +/- 0.1)x10(-6) and B(B-0-> K-0(K) over bar (0))=(0.8 +/- 0.3 +/- 0.1)x10(-6). These decay modes are examples of hadronic b -> d transitions. No signal is observed in the decay B-0-> K+K-, and we set an upper limit of 3.7x10(-7) at 90% confidence level.

We present an improved measurement of the branching fraction for the electroweak penguin process B -> X-sl(l)+(-), where l is an electron or a muon and X-s is a hadronic system containing an s-quark. The measurement is based on a sample of 152x10(6) Upsilon(4S)-> B (B) over bar events collected with the Belle detector at the KEKB energy asymmetric e(+)e(-) collider. The X-s hadronic system is reconstructed from one K+/- or K-S(0) and up to four pions, where at most one pion can be neutral. Averaging over both lepton flavors, the inclusive branching fraction is measured to be B(B -> X-sl(l)+(-))=(4.11 +/- 0.83(stat)(-0.81)(+0.85)(syst))x10(-6) for M-l(l)+(-)> 0.2 GeV/c(2).

In autumn :2003, data taking with the new silicon vertex detector SVD2.0 in Belle started at the KEK-B energy-asymmetric e(+)e(-) collider in Tsukuba, Japan. The detector works as expected, however, it was decided to produce replacement ladders for the inner two layers of the vertex detector which are most exposed to the high radiation dose from the beam. The new ladders do not merely reproduce the existing design but include some significant improvements. The readout electronics is implemented on a hybrid board with a new heat transfer scheme in order to dissipate the heat produced in the front-end readout chip. The flex circuits that connect the double-sided silicon sensors (DSSDs) with the hybrid boards were redesigned using a 2-layer technique which improved the production quality and lowered their costs significantly. Production and testing will be finished in summer 2005 and will provide Belle with spare ladders as well as new expertise for possible future projects for example the high luminosity B-factory.

We report measurements of time-dependent decay rates for B-0-> D*(-/+)pi(+/-) decays and extraction of CP violation parameters related to phi(3). We use a partial reconstruction technique, whereby signal events are identified using information only from the primary pion and the charged pion from the decay of the D*(-/+). The analysis uses 140 fb(-1) of data accumulated at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We measure the CP violation parameters S+ = 0.035 +/- 0.041 (stat) +/- 0.018 (syst) and S- = 0.025 +/- 0.041 (stat) +/- 0.018 (syst). (c) 2005 Elsevier B.V. All rights reserved.

We present the results of a study of the charmless vector-vector decay B+->rho K-+(*0), based on 253 fb(-1) of data collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We obtain the branching fraction B(B+->rho K-+(*0))=[8.9 +/- 1.7(stat)+/- 1.2(syst)]x10(-6). We also perform a helicity analysis of the rho and K-* vector mesons, and obtain the longitudinal polarization fraction f(L)(B+->rho K-+(*0))=0.43 +/- 0.11(stat)(-0.02)(+0.05)(syst).

We present a new measurement of the time-dependent CP-violating parameters in B-0 ->pi(+)pi(-) decays with 275x10(6) B (B) over bar pairs collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider operating at the Upsilon(4S) resonance. We find 666 +/- 43 B-0 ->pi(+)pi(-) events and measure the CP-violating parameters: S-pi pi=-0.67 +/- 0.16(stat)+/- 0.06(syst) and A(pi pi)=+0.56 +/- 0.12(stat)+/- 0.06(syst). We find evidence for large direct CP violation with a significance greater than 4 standard deviations for any S-pi pi value. Using isospin relations, we obtain 95.4% confidence intervals for the Cabibbo-Kobayashi-Maskawa quark-mixing matrix angle phi(2) of 0 degrees <phi(2)< 19 degrees and 71 degrees <phi(2)< 180 degrees.

The Belle Silicon Vertex Detector (SVD) was designed to measure B meson decay positions precisely for studies of time-dependent CP violation. Although the first version of SVD (SVD1) worked for 4years from 1999 with excellent performance, its insufficient radiation hardness drove us to build a second generation SVD (SVD2). The SVD2 was installed in Belle in the summer of 2003 and has been working well. The strip yield is estimated to be more than 95%. The signal-to-noise ratios are obtained to be 18-36, depending on detector ladders. The intrinsic spatial resolutions are obtained to be 12.0 +/- 0.4 and 22.3 +/- 0.8 mu m for phi- and z-sides, where z-side measures positions along the beam direction and 0 side is used for the azimuthal angle measurement. In this letter, an overview and performance results are provided for both generations of the Belle SVD. (c) 2005 Elsevier B.V. All rights reserved.
