First measurement of T-odd moments in D^{0}→K_{S}^{0}π^{+}π^{-}π^{0} decays

We report the first measurement of the T-odd moments in the decay D0→K0Sπ+π−π0 from a data sample corresponding to an integrated luminosity of 966 fb−1 collected by the Belle experiment at the KEKB asymmetric-energy e+e− collider. From these moments we determine the CP-violation-sensitive asymmetry aT-oddCP=[−0.28±1.38(stat.)+0.23−0.76(syst.)]×10−3, which is consistent with no CP violation. In addition, we perform aT−oddCP measurements in different regions of the D0→K0Sπ+π−π0 phase space; these are also consistent with no CP violation

Measurement of the Branching Fraction of the Decay B+→π+π−ℓ+νℓ\boldsymbol{B^{+}\to\pi^{+}\pi^{-}\ell^{+}\nu_\ell} in Fully Reconstructed Events at Belle

We present an analysis of the exclusive $B^{+}\to\pi^{+}\pi^{-}\ell^{+}\nu_{\ell}$ decay, where $\ell$ represents an electron or a muon, with the assumption of charge-conjugation symmetry and lepton universality. The analysis uses the full $\Upsilon(4S)$ data sample collected by the Belle detector, corresponding to 711 fb$^{-1}$ of integrated luminosity. We select the events by fully reconstructing one $B$ meson in hadronic decay modes, subsequently determining the properties of the other $B$ meson. We extract the signal yields using a binned maximum-likelihood fit to the missing-mass squared distribution in bins of the invariant mass of the two pions or the momentum transfer squared. We measure a total branching fraction of ${{\cal B}(B^{+}\to \pi^{+}\pi^{-}\ell^{+}\nu_{\ell})= [22.7 ^{+1.9}_{-1.6} (\mathrm{stat}) \pm 3.5(\mathrm{syst}) ]\times 10^{-5}}$, where the uncertainties are statistical and systematic, respectively. This result is the first reported measurement of this decay.Comment: 23 pages, 19 figure

Observation of an alternative χc0(2P)\chi_{c0}(2P) candidate in e+e−→J/ψDDˉe^+ e^- \rightarrow J/\psi D \bar{D}

We perform a full amplitude analysis of the process $e^+ e^- \rightarrow J/\psi D \bar{D}$, where $D$ refers to either $D^0$ or $D^+$. A new charmoniumlike state $X^*(3860)$ that decays to $D \bar{D}$ is observed with a significance of $6.5\sigma$. Its mass is ($3862^{+26}_{-32}{}^{+40}_{-13}$) MeV/$c^2$ and width is ($201^{+154}_{-67}{}^{+88}_{-82}$) MeV. The $J^{PC}=0^{++}$ hypothesis is favored over the $2^{++}$ hypothesis at the level of $2.5\sigma$. The analysis is based on the 980 $\mathrm{fb}^{-1}$ data sample collected by the Belle detector at the asymmetric-energy $e^+ e^-$ collider KEKB.Comment: 17 pages, 11 figure

Inclusive study of bottomonium production in association with an η\eta meson in e+e−e^+e^- annihilations near Υ(5S)\Upsilon(5S)

We study bottomonium production in association with an $\eta$ meson in $e^+e^-$ annihilations near the $\Upsilon(5S)$, at a center of mass energy of $\sqrt{s}=10.866\,$GeV. The results are based on the $121.4\,$fb$^{-1}$ data sample collected by the Belle experiment at the asymmetric energy KEKB collider. Only the $\eta$ meson is reconstructed and the missing-mass spectrum of $\eta$ candidates is investigated. We observe the $e^+e^-\to\eta\Upsilon_J(1D)$ process and find evidence for the $e^+e^-\to\eta\Upsilon(2S)$ process, while no significant signals of $\Upsilon(1S)$, $h_b(1P)$, nor $h_b(2P)$ are found. Cross sections for the studied processes are reported.Comment: Submitted to EPJ-

Measurement of phi_3 with Dalitz plot analysis of B+ -> D(*)K(*)+ decay

We present a measurement of the unitarity triangle angle phi_3 using a Dalitz plot analysis of the K0_S pi+ pi- decay of the neutral D meson from the B+- -> D(*)K(*)+- process. The method employs the interference between D0 and D0bar to extract the angle phi_3, strong phase Delta and the ratio r of suppressed and allowed amplitudes. We apply this method to a 357 fb-1 data sample collected by the Belle experiment. The analysis uses three modes: B+ -> DK+, B+ -> D*K+ with D* -> Dpi0, and B+ -> DK*+ with K*+ -> K0_S pi+, as well as the corresponding charge-conjugate modes. From a combined maximum likelihood fit to the three modes, we obtain phi_3=53+15-18(stat)+-3(syst)+-9(model) degrees. The corresponding two standard deviation interval is 8<phi_3<111 degrees.Comment: 18 pages, 6 figures, 7 tables. To be submitted to Phys. Rev.

Measurement of the CKM Matrix Element ∣Vcb∣|V_{cb}| from B0→D∗−ℓ+νℓB^{0} \to D^{*-} \ell^+ \nu_\ell at Belle

We present a new measurement of the CKM matrix element $|V_{cb}|$ from $B^{0} \to D^{*-} \ell^+ \nu_\ell$ decays, reconstructed with the full Belle data set of $711 \, \rm fb^{-1}$ integrated luminosity. Two form factor parameterizations, originally conceived by the Caprini-Lellouch-Neubert (CLN) and the Boyd, Grinstein and Lebed (BGL) groups, are used to extract the product $\mathcal{F}(1)\eta_{\rm EW}|V_{cb}|$ and the decay form factors, where $\mathcal{F}(1)$ is the normalization factor and $\eta_{\rm EW}$ is a small electroweak correction. In the CLN parameterization we find $\mathcal{F}(1)\eta_{\rm EW}|V_{cb}| = (35.06 \pm 0.15 \pm 0.56) \times 10^{-3}$, $\rho^{2}=1.106 \pm 0.031 \pm 0.007$, $R_{1}(1)=1.229 \pm 0.028 \pm 0.009$, $R_{2}(1)=0.852 \pm 0.021 \pm 0.006$. For the BGL parameterization we obtain $\mathcal{F}(1)\eta_{\rm EW}|V_{cb}|= (34.93 \pm 0.23 \pm 0.59)\times 10^{-3}$, which is consistent with the World Average when correcting for $\mathcal{F}(1)\eta_{\rm EW}$. The branching fraction of $B^{0} \to D^{*-} \ell^+ \nu_\ell$ is measured to be $\mathcal{B}(B^{0}\rightarrow D^{*-}\ell^{+}\nu_{\ell}) = (4.90 \pm 0.02 \pm 0.16)\%$. We also present a new test of lepton flavor universality violation in semileptonic $B$ decays, $\frac{{\cal B }(B^0 \to D^{*-} e^+ \nu)}{{\cal B }(B^0 \to D^{*-} \mu^+ \nu)} = 1.01 \pm 0.01 \pm 0.03~$. The errors correspond to the statistical and systematic uncertainties respectively. This is the most precise measurement of $\mathcal{F}(1)\eta_{\rm EW}|V_{cb}|$ and form factors to date and the first experimental study of the BGL form factor parameterization in an experimental measurement

Exploration of the Behaviour of a Stochastic Transport Model Using Computational Experiments

Fickian assumptions are used in deriving the advection-dispersion equation which models thesolute transport in porous media. The hydrodynamic dispersion coefficient defined as a result of theseassumptions has been found to be scale dependent. Kulasiri and Verwoerd [1999] developed a stochasticcomputational model for solute transport in saturated porous media without using Fickian assumptions. Themodel consists of two main parameters; correlation length and variance, and the velocity of solute wasassumed as a fundamental stochastic variable. In this paper, the stochastic model was investigated tounderstand its behaviour. As the statistical nature of the model changes with the parameters, thecomputational solution of the model was explored in relation to the parameters. The variance is found to bethe dominant parameter, however, there is a correlation between two parameters and they influence thestochasticity of the flow in a complex manner. We hypothesised that the variance is inversely proportional tothe pore size and the correlation length represents the geometry of flow. The computational results ofdifferent scales show that the hypotheses are reasonable. The model illustrates that it could capture the scaledependence of dispersivity and mimic the advection-dispersion equation in more deterministic situations

Measurement of Branching Fractions of Hadronic Decays of the Ω 0 c Baryon

Using a data sample of 980  fb−1 of e+e− annihilation data taken with the Belle detector operating at the KEKB asymmetric-energy e+e− collider, we report the results of a study of the decays of the Ω0ccharmed baryon into hadronic final states. We report the most precise measurements to date of the relative branching fractions of the Ω0c into Ω−π+π0, Ω−π+π−π+, Ξ−K−π+π+, and Ξ0K−π+, as well as the first measurements of the branching fractions of the Ω0c into Ξ−¯K0π+, Ξ0¯K0, and Λ¯K0¯K0, all with respect to the Ω−π+ decay. In addition, we investigate the resonant substructure of these modes. Finally, we present a limit on the branching fraction for the decay Ω0c→Σ+K−K−π+

Measurement of the branching fraction and CP asymmetry in B 0 → π 0π 0 decays, and an improved constraint on φ2

We measure the branching fraction and CP violation asymmetry in the decay B0→π0π0, using a data sample of 752×106 B¯B pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB e+e− collider. The obtained branching fraction and direct CP asymmetry are B(B→π0π0)=[1.31±0.19(stat)±0.19(syst)]×10−6 and ACP=+0.14±0.36(stat)±0.10(syst), respectively. The signal significance, including the systematic uncertainty, is 6.4 standard deviations. We combine these results with Belle’s earlier measurements of B0→π+π− and B±→π±π0 to exclude the CP-violating parameter ϕ2 from the range 15.5°\u3cϕ
