Abstract: We report the results of a search for D0-D0 mixing in D0 --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'20.72 x 10(-3) and -9.9 x 10(-3)y'6.8 x 10(-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)%.

Abstract: We report results on a Dalitz analysis of three-body charmless B+/- --K+/-pi+/-pi+/- decay including searches for direct CP violation. We report the first observation of the decay B+/- --f2(1270)K+/- with a statistical significance above 6sigma. We also observe first evidence for large direct CP violation in the B+/- --rho(770)0K+/- channel. The results are obtained with a data sample that contains 386 10(6) BB pairs collected at the Y(4s) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider.

Abstract: We report on a search for new resonant states in the process gamma gamma --DD. A candidate C-even charmonium state is observed in the vicinity of 3.93 GeV/c2. The production rate and the angular distribution in the gamma gamma center-of-mass frame suggest that this state is the previously unobserved chi(c2)', the 2(3)P2 charmonium state.

Abstract: We present a measurement of the Cabibbo-Kobayashi-Maskawa matrix element data collected by the Belle detector at the KEKB e+e-asymmetric collider. Events are tagged by fully reconstructing one of the B mesons, produced in pairs from Υ(4S). The signal for b→u semileptonic decay is distinguished from the b→c background using the hadronic mass MX, the leptonic invariant mass squared q2 and the variable P+≡EX-|p→X|. The results are obtained for events with pl*≥1GeV/c, in three kinematic regions (1)MX 8GeV2/c2, and by (3)P+

Abstract: We present an improved measurement of the branching fraction for the electroweak penguin process B->Xsll, where l is an electron or a muon and Xs is a hadronic system containing an s-quark. The measurement is based on a sample of 152*10^6 Upsilon(4S) -> BB events collected with the Belle detector at the KEKB energy asymmetric e+e- collider. The Xs hadronic system is reconstructed from one K^{+-} or K^{0}_{S} 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 Br(B->Xsll)=(4.11+-0.83(stat)+0.85-0.81(syst))*10^{-6} for M_ll > 0.2GeV/c2., Comment: 16 pages 5 figures Latex, Submitted to Physical Review D

Abstract: Using 281fb-1 of data from the Belle experiment recorded at or near the Υ(4S) resonance, we have measured the rates of the "wrong-sign" decays D0→K+π-π0 and D0→K+π-π+π- relative to those of the Cabibbo-favored decays D0→K-π+π0 and D0→K-π+π+π-. These wrong-sign decays proceed via a doubly Cabibbo-suppressed amplitude or via D0-D0 mixing; the latter has not yet been observed. We obtain RWS(Kππ0)=[0.229±0.015(stat)-0.009+0.013(syst)]% and RWS(K3π)=[0.320±0.018(stat)-0.013+0.018(syst)]%. The CP asymmetries are measured to be -0.006±0.053 and -0.018±0.044 for the K+π-π0 and K+π-π+π- final states, respectively. © 2005 The American Physical Society.

Abstract: We present a measurement of CP-violation parameters in the B0 --> K(s)0K(s)0K(s)0 decay based on a sample of 275 x 10(6) BB pairs collected at the upsilon(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. One neutral B meson is fully reconstructed in the decay B0 --> K(s)0K(s)0K(s)0, and the flavor of the accompanying B meson is identified from its decay products. CP-violation parameters are obtained from the asymmetry in the distributions of the proper-time interval between the two B decays: S = +1.26 +/- 0.68(stat) +/- 0.20(syst) and [symbol: see text] = +0.54 +/- 0.34(stat) +/- 0.09(syst).

Abstract: We report evidence for B{sup 0}{yields}D{sup +}D{sup -} and the first observation of the decay modes B{sup -}{yields}D{sup 0}D{sup -} and B{sup -}{yields}D{sup 0}D{sup *-} based on a sample of 152x10{sup 6} BB events collected by the Belle detector at KEKB. The branching fractions for B{sup 0}{yields}D{sup +}D{sup -}, B{sup -}{yields}D{sup 0}D{sup -}, and B{sup -}{yields}D{sup 0}D{sup *-} are found to be (1.91{+-}0.51{+-}0.30)x10{sup -4} (4.83{+-}0.78{+-}0.58)x10{sup -4}, and (4.57{+-}0.71{+-}0.56)x10{sup -4}, respectively. Charge asymmetries in the B{sup -}{yields}D{sup 0}D{sup -} and B{sup -}{yields}D{sup 0}D{sup *-} channels are consistent with zero.

Abstract: Using 281 fb-1 of data from the Belle experiment recorded at or near the (4S) resonance, we have measured the rates of the "wrong-sign" decays D0 --K+ pi- pi0 and D0 --K+ pi- pi+ pi- relative to those of the Cabibbo-favored decays D0 --K- pi+ pi0 and D0 --K- pi+ pi+ pi-. These wrong-sign decays proceed via a doubly Cabibbo-suppressed amplitude or via D0-D0 mixing; the latter has not yet been observed. We obtain R(WS)(K pi pi0) = [0.229 +/- 0.015(stat)(+0.013)(-0.009)(syst)]% and R(WS)(K3pi) = [0.320 +/- 0.018(stat)(+0.018)(0.013)(syst)]%. The CP asymmetries are measured to be -0.006 +/- 0.053 and -0.018 +/- 0.044 for the K+ pi- pi0 and K+ pi- pi+ pi- final states, respectively.

Abstract: We report measurements of B to pseudoscalar-pseudoscalar decays with at least one {eta} meson in the final state using 140 fb{sup -1} of data collected by the Belle detector at KEKB e{sup +}e{sup -} collider. We observe the decay B{sup +}{yields}{eta}{pi}{sup +} and find evidence of B{sup +}{yields}{eta}K{sup +}; the measured branching fractions are B(B{sup +}{yields}{eta}{pi}{sup +})=(4.8{sub -0.7}{sup +0.8}(stat){+-}0.3(sys))x10{sup -6} and B(B{sup +}{yields}{eta}K{sup +})=(2.1{+-}0.6(stat){+-}0.2(sys))x10{sup -6}. Their corresponding CP violating asymmetries are measured to be 0.07{+-}0.15(stat){+-}0.03(sys) for {eta}{pi}{sup {+-}} and -0.49{+-}0.31(stat){+-}0.07(sys) for {eta}K{sup {+-}}. No significant signals are found for neutral B{yields}{eta}h decays. We report the following upper limits on branching fractions at the 90% confidence level: B(B{sup 0}{yields}{eta}K{sup 0})

Abstract: We report results on the Dalitz analysis of three-body charmless B+ -> K+ pi(+) pi(-) and B+-> K+ K+ K- decays based on a 140 fb(-1) data sample collected with the Belle detector. Measurements of branching fractions for quasi-two-body decays to scalar-pseudoscalar states: B+ -> f(0)(980)K+, B+ -> K-0(*)(1430)(0)pi(+), and to vector-pseudoscalar states: B+ -> K-*(892)(0)pi(+), B+ -> rho(0)K(+), B+ -> phi K+ are presented. Upper limits on decays to some pseudoscalar-tensor final states are reported. We also report the measurement of the B+ -> chi(c0)K(+) branching fraction in two chi(c0) decays channels: chi(c0) -> pi(+)pi(-) and chi(c0) -> K+K-.

Abstract: We present a measurement of CP-violation parameters in the B0 --K(s)0K(s)0K(s)0 decay based on a sample of 275 x 10(6) BB pairs collected at the upsilon(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider. One neutral B meson is fully reconstructed in the decay B0 --K(s)0K(s)0K(s)0, and the flavor of the accompanying B meson is identified from its decay products. CP-violation parameters are obtained from the asymmetry in the distributions of the proper-time interval between the two B decays: S = +1.26 +/- 0.68(stat) +/- 0.20(syst) and [symbol: see text] = +0.54 +/- 0.34(stat) +/- 0.09(syst).

Abstract: We report evidence for B(0) --D(0)D(-) and the first observation of the decay modes B(-) --D(0)D(-) and B(-) --D(0)D(*-) based on a sample of 152 x 10(6) BB events collected by the Belle detector at KEKB. The branching fractions for B(0) --D(+) D(-), B---D(0)D(-), and B--D(0)D(*-) are found to be (1.91 +/- 0.51 +/- 0.30) x10(-4), (4.83 +/- 0.78 +/- 0.58) x 10(-4), and (4.57 +/- 0.71 +/- 0.56) x 10(-4), respectively. Charge asymmetries in the B---D(0)D(-) and B(-) --D(0)D(*-) channels are consistent with zero.

Abstract: We report a study of the suppressed decays B---[K(+)pi(-)](D)K- and B---[K(+)pi(-)](D)pi(-), where [K(+)pi(-)](D) indicates that the K+pi(-) pair originates from a neutral D meson. These decay modes are sensitive to the unitarity triangle angle varphi(3). We use a data sample containing 275 x 10(6) BB pairs recorded at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric e(+)e(-) storage ring. The signal for B---[K(+)pi(-)](D)K- is not statistically significant, and we set a limit r(B)0.27 at 90% confidence level, where r(B) is the magnitude of the ratio of amplitudes |A(B---D 0K-)/A(B---D0K-)|. We observe a signal with 6.4sigma statistical significance in the related mode, B---[K(+)pi(-)](D)pi(-).

Abstract: The decays B0--D+sJK- and B0--D-sJpi+ are studied for the first time. A significant signal is observed in the B0--D*sJ(2317)+K- decay channel with B(B0--D*sJ(2317)+K-) x B(D*sJ(2317)+--D+spi0)=(5.3(+1.5)(-1.3)+/-0.7+/-1.4) x 10(-5). No signals are observed in the B0--D*sJ(2317)-pi+, B0--DsJ(2460)+K-, and B 0--DsJ(2460)-pi+ decay modes, and upper limits are obtained. The analysis is based on a data set of 140 fb(-1) collected by the Belle experiment at the asymmetric e+e- collider KEKB.

Abstract: The evidence for direct charged particles (CP) violation in the decay B0→K+ π- was investigated with 253 fb-1 of data collected with the Belle detector at the KEKB e + e- collider. 275 x 106 BB pairs were used to observe a B→K±π∓ signal with 2140 ±53 events. Mixing induced CP violation in the B sector was established in b → ccs transitions. The result suggests large interference between tree and penguin diagrams and the existence of final state interactions.

Abstract: We report evidence for the decay $B^0 \to \pi^0 \pi^0$. The analysis is based on a data sample of 152 million $B\bar{B}$ pairs collected at the $\Upsilon(4s)$ resonance with the Belle detector at the KEKB $e^+ e^-$ storage ring. We find $25.6^{+ 9.3}_{-8.4}(stat)^{+1.6}_{-1.4}(syst)$ $B^0 \to \pi^0 \pi^0$ signal events with a significance of 3.4 standard deviations. We measure the branching fraction to be ($1.7 \pm 0.6 (stat) \pm 0.2 (syst))*10^{-6}$.

Abstract: We report the first observation of the charmless vector-vector decay process B-/+-->rho(-/+)rho(0). The measurement uses a 78 fb(-1) data sample collected with the Belle detector at the KEKB asymmetric e(+)e(-) collider operating at the Y(4S) resonance. We obtain a branching fraction of B (B-/+-->rho(-/+)rho(0))=[31.7+/-7.1(stat)(-6.7)(+3.8)(syst)]x10(-6). An analysis of the rho helicity-angle distributions gives a longitudinal polarization fraction of Gamma(L)/Gamma=0.95+/-0.11(stat)+/-0.02(syst). We also measure the direct-CP-violating asymmetry A(CP)(B-/+-->rho(-/+)rho(0))=0.00+/-0.22(stat)+/-0.03(syst).

Abstract: We have performed a search for the lepton-flavor-violating decay tau--microgamma using a data sample of 86.3 fb(-1) accumulated by the Belle detector at KEK. No evidence for a signal is seen, and we set an upper limit for the branching fraction of B(tau--microgamma)3.1 x 10(-7) at the 90% confidence level.

Abstract: We report results on the decay $B^{-} \to D_{CP}K^{-}$ and its charge conjugate using a data sample of 85.4 million $B\bar{B}$ pairs recorded at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric $e^{+}e^{-}$ storage ring. Ratios of branching fractions of Cabibbo-suppressed to Cabibbo-favored processes are determined to be ${\cal B}(B^- \to D^0 K^-)/{\cal B}(B^- \to D^0 \pi^-)= 0.077 \pm 0.005(stat) \pm 0.006(sys)$, ${\cal B}(B^- \to D_1 K^-)/{\cal B}(B^- \to D_1 \pi^-) = 0.093 \pm 0.018(stat) \pm 0.008(sys)$ and ${\cal B}(B^- \to D_2 K^-)/{\cal B}(B^- \to D_2 \pi^-) = 0.108 \pm 0.019(stat) \pm 0.007(sys)$ where the indices 1 and 2 represent the CP=+1 and CP=$-$1 eigenstates of the $D^{0}-\bar{D^{0}}$ system, respectively. We find the partial-rate charge asymmetries for $B^{-} \to D_{CP}K^{-}$ to be ${\cal{A}}_1 = 0.06 \pm 0.19(stat) \pm 0.04(sys)$ and ${\cal{A}}_2 = -0.19 \pm 0.17(stat) \pm 0.05(sys)$.

Abstract: We report an improved measurement of the partial-rate CP asymmetry in B±→K0π± decays. The analysis is based on a data sample of 85×106 BB pairs collected at the Y(4S) resonance with the Belle detector at the KEKB e +e- storage ring. We measure ACP(K 0π±) = 0.07-0.08 +0.09 +0.03 +0.01, where the first and second errors are statistical and systematic, respectively; the corresponding 90% confidence-level interval is -0.10

Abstract: We report measurements of the properties of the $D_{sJ}^+(2317)$ and $D_{sJ}^+(2457)$ resonances produced in continuum $e^+ e^-$ annihilation near $\sqrt{s}=10.6 \mathrm{GeV}$. The analysis is based on an $86.9 \mathrm{fb^{-1}}$ data sample collected %at and 60 MeV below the $\Upsilon(4S)$ resonance with with the Belle detector at KEKB. We determine the masses to be $M(D_{sJ}^+(2317)) = 2317.2 \pm 0.5(\mathrm{stat}) \pm 0.9(\mathrm{syst}) \mathrm{MeV}/c^2$ and $M(D_{sJ}^+(2457))=2456.5 \pm 1.3(\mathrm{stat}) \pm 1.3(\mathrm{syst}) \mathrm{MeV}/c^2$. We observe the radiative decay mode $D_{sJ}^+(2457) \to D_s^+ \gamma$ and the dipion decay mode $D_{sJ}^+(2457) \to D_s^+ \pi^+ \pi^-$, and determine their branching fractions. No corresponding decays are observed for the $D_{sJ}(2317)$ state. These results are consistent with the spin-parity assignments of $0^+$ for the $D_{sJ}(2317)$ and $1^+$ for the $D_{sJ}(2457)$., Comment: 5 pages, 6 figures; Added content, updated and paper submitted to PRL

Abstract: We present an improved measurement of CP-violating asymmetries in B 0→π+π- decays based on a 78 fb -1 data sample collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+ e- collider. We reconstruct one neutral B meson as a B0→π+π - CP eigenstate and identify the flavor of the accompanying B meson from inclusive properties of its decay products. We apply an unbinned maximum likelihood fit to the distribution of the time intervals between the two B meson decay points. The fit yields the CP-violating asymmetry amplitudes A ππ= +0.77 ±0.27(stat) ±0.08(syst) and S ππ=-1.23 ±0.41(stat) -0.07 +0.08(syst), where the statistical uncertainties are determined from the Monte Carlo pseudoexperiments. We obtain confidence intervals for CP-violating asymmetry parameters Aππ and Sππ based on a frequentist approach. We rule out the CP-conserving case, A ππ=Sππ=0, at the 99.93% confidence level. We discuss how these results constrain the value of the Cabibbo-Kobayashi-Maskawa (CKM) angle φ2. © 2003 The American Physical Society.

Abstract: We report the first observation of the charmless vector-vector decay process B-/+--rho(-/+)rho(0). The measurement uses a 78 fb(-1) data sample collected with the Belle detector at the KEKB asymmetric e(+)e(-) collider operating at the Upsilon(4S) resonance. We obtain a branching fraction of B(B-/+--rho(-/+)rho(0))=[31.7+/-7.1(stat)+3.8-6.7(syst)]x10(-6). An analysis of the rho helicity-angle distributions gives a longitudinal polarization fraction of Gamma(L)/Gamma=0.95+/-0.11(stat)+/-0.02(syst). We also measure the direct-CP-violating asymmetry A(CP)(B-/+--rho(-/+)rho(0))=0.00+/-0.22(stat)+/-0.03(syst).

Abstract: We report evidence for the decay mode B--phiphiK based on an analysis of 78 fb(-1) of data collected with the Belle detector at KEKB. This is the first example of a b--sssss transition. The branching fraction for this decay is measured to be B(B+/---phiphiK+/-)=(2.6(+1.1)(-0.9)+/-0.3)x10(-6) for a phiphi invariant mass below 2.85 GeV/c(2). Results for other related charmonium decay modes are also reported.

Abstract: We report studies of the Cabibbo-suppressed decay B+/- --> DCPK+/-, where D-CP denotes CP eigenstates of the D-0 - (D) over bar (0) system. The analysis is based on a 29.1 fb(-1) sample collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric e(+)e(-) storage ring. We measure ratios of branching fractions, relative to Cabibbo-favored B+/--->D(CP)pi+/-, of B>(B- --> D1K-)/B(B- --> D(1)pi(-)) = 0.125 +/-0.036 +/- 0.010 and B(B- --> D2K-)/B(B- --> D(2)pi(-)) = 0.119 +/- 0.028 +/- 0.006; the index 1 (2) denotes the CP = +1 (-1) eigenstate. We also extract the partial rate asymmetries for B+/- --> DCPK+/-, finding A(1) = 0.29 +/- 0.26 +/- 0.05 and A(2) = -0.22 +/- 0.24 +/- 0.04.

Abstract: We report the measurement of the charmed baryonic decay ${\overline{B}}^{0}\ensuremath{\rightarrow}{\ensuremath{\Lambda}}_{c}^{+}\overline{p}$ with a branching fraction of $({2.19}_{\ensuremath{-}0.49}^{+0.56}\ifmmode\pm\else\textpm\fi{}0.32\ifmmode\pm\else\textpm\fi{}0.57)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$ and a statistical significance of $5.8\text{ }\ensuremath{\sigma}$. The errors are statistical, systematic, and the error of the ${\ensuremath{\Lambda}}_{c}^{+}\ensuremath{\rightarrow}p{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$ decay branching fraction. This is the first observation of a two-body baryonic $B$ decay. The analysis is based on $78.2\text{ }{\mathrm{f}\mathrm{b}}^{\ensuremath{-}1}$ of data accumulated at the $\ensuremath{\Upsilon}(4S)$ resonance with the Belle detector at the KEKB asymmetric ${e}^{+}{e}^{\ensuremath{-}}$ collider.

Abstract: We present a measurement of CP-violation parameters in the b→sqq penguin transitions (q = s,u,d) based on a 78 fb-1 data sample collected at the Y(4S) resonance with the Belle detector at the KEKB energyasymmetric e+e- collider. One neutral B meson is reconstructed in the φKS 0, K+K -KS 0, or η′ KS 0 decay channel, and the flavor of the accompanying B meson is identified from its decay products. CP violation parameters for each of the three modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays. © 2003 The American Physical Society.

Abstract: We report measurements of branching fractions for charged and neutral $B\ensuremath{\rightarrow}{\ensuremath{\eta}}_{c}K$ decays where the ${\ensuremath{\eta}}_{c}$ meson is reconstructed in the ${K}_{S}^{0}{K}^{\ifmmode\pm\else\textpm\fi{}}{\ensuremath{\pi}}^{\ensuremath{\mp}}$, ${K}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}$, ${K}^{*0}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$, and $p\overline{p}$ decay channels. The neutral ${B}^{0}$ channel is a $CP$ eigenstate and can be used to measure the $CP$ violation parameter $\mathrm{sin} 2{\ensuremath{\varphi}}_{1}$. We also report the first observation of the ${B}^{0}\ensuremath{\rightarrow}{\ensuremath{\eta}}_{c}{K}^{*0}$ mode. The results are based on an analysis of $29.1\text{ }{\mathrm{f}\mathrm{b}}^{\ensuremath{-}1}$ of data collected by the Belle detector at KEKB.

Abstract: We report the first measurement of the branching fraction for the inclusive decay B → X s l + l - , where l is either an electron or a muon, and X s is a hadronic recoil system that contains an s quark. We analyzed a data sample of 65.4 x 10 6 B meson pairs collected with the Belle detector at the KEKB e + e - asymmetric-energy collider. We find B(B → X s l + l - ) = [6.1 ′ 1.4(stat) + 1 . 4 - 1 . 1 (syst)] × 10 - 6 for dilepton masses greater than 0.2 GeV/c 2 .

Abstract: We present a measurement of the B0-Bmacr;(0) mixing parameter Deltam(d) using neutral B meson pairs in a 29.1 fb(-1) data sample collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We exclusively reconstruct one neutral B meson in the semileptonic B0-->D(*-)l(+)nu decay mode and identify the flavor of the accompanying B meson from its decay products. From the distribution of the time intervals between the two flavor-tagged B meson decay points, we obtain Deltam(d)=(0.494+/-0.012+/-0.015) ps(-1), where the first error is statistical and the second error is systematic.

Abstract: We report the observation of prompt $J/\ensuremath{\psi}$ via double $c\overline{c}$ production from the ${e}^{+}{e}^{\ensuremath{-}}$ continuum. In this process one $c\overline{c}$ pair fragments into a $J/\ensuremath{\psi}$ meson while the remaining pair either produces a charmonium state or fragments into open charm. Both cases have been experimentally observed. We find cross sections of $\ensuremath{\sigma}[{e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}J/\ensuremath{\psi}{\ensuremath{\eta}}_{c}(\ensuremath{\gamma})]\ifmmode\times\else\texttimes\fi{}\mathcal{B}({\ensuremath{\eta}}_{c}\ensuremath{\rightarrow}\ensuremath{\ge}4\text{ }\text{ }\mathrm{\text{charged}})=({0.033}_{\ensuremath{-}0.006}^{+0.007}\ifmmode\pm\else\textpm\fi{}0.009)\text{ }\text{ }\mathrm{p}\mathrm{b}$ and $\ensuremath{\sigma}({e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}J/\ensuremath{\psi}{D}^{*+}X)=({0.53}_{\ensuremath{-}0.15}^{+0.19}\ifmmode\pm\else\textpm\fi{}0.14)\text{ }\text{ }\mathrm{p}\mathrm{b}$ and infer $\ensuremath{\sigma}({e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}J/\ensuremath{\psi}c\overline{c})/\ensuremath{\sigma}({e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}J/\ensuremath{\psi}X)={0.59}_{\ensuremath{-}0.13}^{+0.15}\ifmmode\pm\else\textpm\fi{}0.12$. These results are obtained from a $46.2\text{ }\text{ }{\mathrm{f}\mathrm{b}}^{\ensuremath{-}1}$ data sample collected near the $\ensuremath{\Upsilon}(4S)$ resonance, with the Belle detector at the KEKB collider.
