We report measurements of branching fractions ($\mathcal B$) and direct ${\it CP}$-violating asymmetries ($\mathcal A_{\it CP}$) for the decays $B^+\to K^+\pi^0$ and $B^+ \to \pi^+\pi^0$ reconstructed with the Belle II detector in a sample of asymmetric-energy electron-positron collisions at the $\Upsilon(4S)$ resonance corresponding to 62.8 $\text{fb}^{-1}$ of integrated luminosity. The results are $\mathcal{B}(B^+ \to K^+\pi^0) = [11.9 ^{+1.1}_{-1.0} (\rm stat)\pm 1.6(\rm syst)]\times 10^{-6}$, $\mathcal{B}(B^+ \to \pi^+\pi^0) = [5.5 ^{+1.0}_{-0.9} (\rm stat)\pm 0.7(\rm syst)]\times 10^{-6}$, $\mathcal A_{\it CP}(B^+ \to K^+\pi^0) = -0.09 \pm 0.09 (\rm stat)\pm 0.03(\rm syst)$, and $\mathcal A_{\it CP}(B^+ \to \pi^+\pi^0) = -0.04 \pm 0.17 (\rm stat)\pm 0.06(\rm syst)$. The results are consistent with previous measurements and show a detector performance comparable with early Belle performance.

We present measurements of the branching fractions for the decays $B\to K \mu^{+}\mu^{-}$ and $B\to K e^{+}e^{-}$, and their ratio ($R_{K}$), using a data sample of 711 $fb^{-1}$ that contains $772 \times 10^{6}$ $B\bar{B}$ events. The data were collected at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^{+}e^{-}$ collider. The ratio $R_{K}$ is measured in five bins of dilepton invariant-mass-squared ($q^{2}$): $q^{2} \in (0.1, 4.0), (4.0, 8.12), (1.0, 6.0)$, $(10.2, 12.8)$ and ($>14.18) GeV^{2}/c^{4}$, along with the whole $q^2$ region. The $R_{K}$ value for $q^{2} \in (1.0, 6.0) GeV^{2}/c^{4}$ is $1.03^{+0.28}_{-0.24} \pm 0.01$. The first and second uncertainties listed are statistical and systematic, respectively. All results for $R_{K}$ are consistent with Standard Model predictions. We also measure $C\!P$-averaged isospin asymmetries in the same $q^{2}$ bins. The results are consistent with a null asymmetry, with the largest difference of 2.6 standard deviations occurring for the $q^{2}\in(1.0,6.0) GeV^{2}/c^{4}$ bin in the mode with muon final states. The measured differential branching fractions, ${d\cal B}/{dq^{2}}$, are consistent with theoretical predictions for charged $B$ decays, while the corresponding values are below the expectations for neutral $B$ decays. We have also searched for lepton-flavor-violating $B \rightarrow K\mu^{\pm}e^{\mp}$ decays and set $90\%$ confidence-level upper limits on the branching fraction in the range of $10^{-8}$ for $B^{+} \rightarrow K^{+}\mu^{\pm}e^{\mp}$, and $B^{0} \rightarrow K^{0}\mu^{\pm}e^{\mp}$ modes., Comment: 18 pages, 7 figures

We present a measurement of $R_{K^{\ast}}$, the branching fraction ratio ${{\cal B}(B\to K^\ast \mu^+ \mu^-)}$/ ${{\cal B}(B\to K^\ast e^+ e^-)}$, for both charged and neutral $B$ mesons. The ratio for the charged case, $R_{K{^{\ast +}}}$, is the first measurement ever performed. In addition, we report absolute branching fractions for the individual modes in bins of the squared dilepton invariant mass, $q^2$. The analysis is based on a data sample of $711~\mathrm{fb}^{-1}$, containing $772\times 10^{6}$ $B\bar B$ events, recorded at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. The obtained results are consistent with Standard Model expectations., Comment: Submitted to PRL

We report the first measurement of the charm-mixing parameter y$_{CP}$ in D$^{0}$ decays to the CP-odd final state K0¦Sω. The study uses the full Belle e$^{+}$e$^{-}$ annihilation data sample of 976 fb$^{-1}$ taken at or near the Υ(4S) centre-of-mass energy. We find y$_{CP}$=(0.96±0.91±0.62(+0.17)¦(-0.00))%, where the first uncertainty is statistical, the second is systematic due to event selection and background, and the last is due to possible presence of CP-even decays in the data sample.

We report the study of \OK \ and \SK \ using a $772 \times 10^6$ $B\bar{B}$ pair data sample recorded on the $\Upsilon({\rm 4S})$ resonance with the Belle detector at KEKB. The following branching fractions are measured: $\mathcal{B}$(\OKPHSP) $=$ $(4.22^{+0.45}_{-0.44}\pm 0.51)\times10^{-6}$, $\mathcal{B}$(\SKPHSP) $=$ $(3.81^{+0.39}_{-0.37} \pm 0.45)\times 10^{-6}$, $\mathcal{B}$(\ETACD+c.c.) $=$ $(2.91^{+0.37}_{-0.35}\pm 0.36)\times 10^{-3}$ and $\mathcal{B}$(\PLPHI) $=$ $(8.18 \pm 2.15 \pm 0.79)\times10^{-7}$, where c.c. denotes the corresponding charge-conjugation process. The intermediate resonance decays are excluded in the four-body decay measurements. We also found evidences for $\mathcal{B}$(\ETACS+c.c.) $=$ $(3.59 \pm 1.52 \pm 0.47) \times 10^{-3}$ and $\mathcal{B}$(\LLKO) $=$ $(2.30 \pm 0.65 \pm 0.25) \times 10^{-6}$. No significant signals are found for \JPSIS+c.c. and \LLKS \ ; we set the 90\% confidence level upper limits on their decay branching fractions as $< 1.85\times10^{-3}$ and $< 2.14\times10^{-6}$, respectively., Comment: 20 pages, 7 figures, 3 tables Submitted to Phys.

We report a search for the charmless baryonic decay $B^0\to p\bar{p}\pi^0$ with a data sample corresponding to an integrated luminosity of 711~$\rm fb^{-1}$ containing $(772\pm 10)\times 10^6$ $B^0\bar{B}^0$ pairs. The data was collected by the Belle experiment running on the $\Upsilon(4S)$ resonance at the KEKB $e^+e^-$ collider. We measure a branching fraction $\mathcal{B}(B^0\to p\bar{p}\pi^0)= (5.0\pm1.8\pm0.6 )\times 10^{-7}$, where the first uncertainty is statistical and the second is systematic. The signal has a significance of 3.1 standard deviations and constitutes the first evidence for this decay mode. We also search for the intermediate two-body decays $B^{0}\to\Delta^+\bar{p}$ and $B^0\to\bar{\Delta}^-p$, and set an upper limit on the branching fraction: $\mathcal{B}(B^0\to \Delta^+\bar{p})+\mathcal{B}(B^0\to\bar{\Delta}^-p), Comment: 8 pages, 3 figures, Submitted to Phys.

The experimental results on the ratios of branching fractions $\mathcal{R}(D) = {\cal B}(\bar{B} \to D \tau^- \bar{\nu}_{\tau})/{\cal B}(\bar{B} \to D \ell^- \bar{\nu}_{\ell})$ and $\mathcal{R}(D^*) = {\cal B}(\bar{B} \to D^* \tau^- \bar{\nu}_{\tau})/{\cal B}(\bar{B} \to D^* \ell^- \bar{\nu}_{\ell})$, where $\ell$ denotes an electron or a muon, show a long-standing discrepancy with the Standard Model predictions, and might hint to a violation of lepton flavor universality. We report a new simultaneous measurement of $\mathcal{R}(D)$ and $\mathcal{R}(D^*)$, based on a data sample containing $772 \times 10^6$ $B\bar{B}$ events recorded at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB $e^+ e^-$ collider. In this analysis the tag-side $B$ meson is reconstructed in a semileptonic decay mode and the signal-side $\tau$ is reconstructed in a purely leptonic decay. The measured values are $\mathcal{R}(D)= 0.307 \pm 0.037 \pm 0.016$ and $\mathcal{R}(D^*) = 0.283 \pm 0.018 \pm 0.014$, where the first uncertainties are statistical and the second are systematic. These results are in agreement with the Standard Model predictions within $0.2$, $1.1$ and $0.8$ standard deviations for $\mathcal{R}(D)$, $\mathcal{R}(D^*)$ and their combination, respectively. This work constitutes the most precise measurements of $\mathcal{R}(D)$ and $\mathcal{R}(D^*)$ performed to date as well as the first result for $\mathcal{R}(D)$ based on a semileptonic tagging method., Comment: 8 pages, 1 figure, submitted to Physical Review Letters

International audience; We present the first measurements of absolute branching fractions of Ξc0 decays into Ξ-π+, ΛK-π+, and pK-K-π+ final states. The measurements are made using a dataset comprising (772±11)×106 BB¯ pairs collected at the ϒ(4S) resonance with the Belle detector at the KEKB e+e- collider. We first measure the absolute branching fraction for B-→Λ¯c-Ξc0 using a missing-mass technique; the result is B(B-→Λ¯c-Ξc0)=(9.51±2.10±0.88)×10-4. We subsequently measure the product branching fractions B(B-→Λ¯c-Ξc0)B(Ξc0→Ξ-π+), B(B-→Λ¯c-Ξc0)B(Ξc0→ΛK-π+), and B(B-→Λ¯c-Ξc0)B(Ξc0→pK-K-π+) with improved precision. Dividing these product branching fractions by the result for B-→Λ¯c-Ξc0 yields the following branching fractions: B(Ξc0→Ξ-π+)=(1.80±0.50±0.14)%, B(Ξc0→ΛK-π+)=(1.17±0.37±0.09)%, and B(Ξc0→pK-K-π+)=(0.58±0.23±0.05)%. For the above branching fractions, the first uncertainties are statistical and the second are systematic. Our result for B(Ξc0→Ξ-π+) can be combined with Ξc0 branching fractions measured relative to Ξc0→Ξ-π+ to yield other absolute Ξc0 branching fractions.

- Abstract
The Belle II detector will provide a major step forward in precision heavy flavor physics, quarkonium and exotic states, searches for dark sectors, and many other areas. The sensitivity to a large number of key observables can be improved by about an order of magnitude compared to the current measurements, and up to two orders in very clean search measurements. This increase in statistical precision arises not only due to the increased luminosity, but also from improved detector efficiency and precision for many channels. Many of the most interesting observables tend to have very small theoretical uncertainties that will therefore not limit the physics reach. This book has presented many new ideas for measurements, both to elucidate the nature of current anomalies seen in flavor, and to search for new phenomena in a plethora of observables that will become accessible with the Belle II dataset. The simulation used for the studiesinthis book was state ofthe artat the time, though weare learning a lot more about the experiment during the commissioning period. The detector is in operation, and working spectacularly well.

- Abstract
We report the first observation of the Îc(2930)0 charmed-strange baryon with a significance greater than 5 Ï . The Îc(2930)0 is found in its decay to K-Îc+ in B-âK-Îc+ίc- decays. The measured mass and width are [2928.9±3.0(stat.)-12.0+0.9(syst.)]  MeV/ c2 and [19.5±8.4(stat.)-7.9+5.9(syst.)]  MeV, respectively, and the product branching fraction is B(B-âÎc(2930)0ίc-)B(Îc(2930)0âK-Îc+)=[1.73±0.45(stat.)±0.21(syst.)]Ã10-4 . We also measure B(B-âK-Îc+ίc-)=[4.80±0.43(stat.)±0.60(syst.)]Ã10-4 with improved precision, and search for the charmonium-like state Y (4660) and its spin partner, Yη , in the Îc+ίc- invariant mass spectrum. No clear signals of the Y (4660) nor its spin partner are observed and the 90% credibility level (C.L.) upper limits on their production rates are determined. These measurements are obtained from a sample of (772±11)Ã106BB¯ pairs collected at the Î¥(4S) resonance by the Belle detector at the KEKB asymmetric energy electronâpositron collider.

- Abstract
The Majorana Collaboration is operating an array of high purity Ge detectors to search for neutrinoless double-β decay in Ge76. The Majorana Demonstrator comprises 44.1 kg of Ge detectors (29.7 kg enriched in Ge76) split between two modules contained in a low background shield at the Sanford Underground Research Facility in Lead, South Dakota. Here we present results from data taken during construction, commissioning, and the start of full operations. We achieve unprecedented energy resolution of 2.5 keV FWHM at Qββ and a very low background with no observed candidate events in 9.95 kg yr of enriched Ge exposure, resulting in a lower limit on the half-life of 1.9×1025 yr (90% C.L.). This result constrains the effective Majorana neutrino mass to below 240-520 meV, depending on the matrix elements used. In our experimental configuration with the lowest background, the background is 4.0-2.5+3.1 counts/(FWHM t yr).

- Abstract
We report a measurement of the B0 and B+ meson decays to the Ds-KS0?+ and Ds-K+K+ final states, respectively, using 657�106BB� pairs collected at the ?(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. Using the Ds-???-, K?(892)0K- and KS0K- decay modes for the Ds reconstruction, we measure the following branching fractions: B(B0?Ds-KS0?+)=[0.47�0.06(stat)�0.05(syst)]�10-4 and B(B+?Ds-K+K+)=[0.93�0.22(stat)�0.10(syst)]�10-5. We find the ratio of the branching fraction of B+?Ds-K+K+ to that of the analogous Cabibbo-favored B+?Ds-K+?+ decay to be RB=0.054�0.013(stat)�0.006(syst), which is consistent with the naive factorization model. We also observe a deviation of the DsK invariant-mass distribution from the three-body phase-space model for both studied decays. � 2015 American Physical Society.

- Abstract
We report results on studies of the e+e-annihilation into three-body (nS)?+?-(n=1,2,3) final states including measurements of cross sections and the full amplitude analysis. The cross sections measured at s=10.866GeV and corrected for the initial state radiation are ?(e+e-? (1S)?+?-)=(2.27�0.12�0.14)pb, ?(e+e-? (2S)?+?-)=(4.07�0.16�0.45)pb, and ?(e+e-? (3S)?+?-)=(1.46�0.09�0.16)pb. Amplitude analysis of the three-body (nS)?+?-final states strongly favors IG(JP)=1+(1+) quantum-number assignments for the two bottomonium-like Zb� states, recently observed in the (nS)?� and hb(mP)?� (m=1,2) decay channels. The results are obtained with a 121.4fb-1 data sample collected with the Belle detector at the KEKB asymmetric-energy e+e-collider. � 2015 American Physical Society.

- Abstract
We report a measurement of the branching fraction ratios R(D(?)) of B�?D(?)?-?�? relative to B�?D(?) -?� (where =e or ?) using the full Belle data sample of 772�106BB� pairs collected at the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. The measured values are R(D)=0.375�0.064(stat)�0.026(syst) and R(D?)=0.293�0.038(stat)�0.015(syst). The analysis uses hadronic reconstruction of the tag-side B meson and purely leptonic ? decays. The results are consistent with earlier measurements and do not show a significant deviation from the standard model prediction. � 2015 American Physical Society. � 2015 American Physical Society.

- Abstract
We report measurement of the cross section of e+e-??+?-?(2S) between 4.0 and 5.5 GeV, based on an analysis of initial state radiation events in a 980fb-1 data sample recorded with the Belle detector. The properties of the Y(4360) and Y(4660) states are determined. Fitting the mass spectrum of ?+?-?(2S) with two coherent Breit-Wigner functions, we find two solutions with identical mass and width but different couplings to electron-positron pairs: MY(4360)=(4347�6�3)MeV/c2, ?Y(4360)=(103�9�5)MeV, MY(4660)=(4652�10�8)MeV/c2, ?Y(4660)=(68�11�1)MeV, and B[Y(4360)??+?-?(2S)]�?Y(4360)e+e-=(10.9�0.6�0.7)eV and B[Y(4660)??+?-?(2S)]�?Y(4660)e+e-=(8.1�1.1�0.5)eV for one solution, or B[Y(4360)??+?-?(2S)]�?Y(4360)e+e-=(9.2�0.6�0.6)eV and B[Y(4660)??+?-?(2S)]�?Y(4660)e+e-=(2.0�0.3�0.2)eV for the other. Here, the first errors are statistical and the second systematic. Evidence for a charged charmoniumlike structure at 4.05GeV/c2 is observed in the ?�?(2S) intermediate state in the Y(4360) decays. � 2015 American Physical Society.

We report on the first observations of B�0?D1(2430)0?, B�0?D1(2420)0?, and B�0?D2?(2460)0? decays. The B�0?D?+?(1450)- decay is also observed. The branching fraction measurements are based on (771.6�10.6)�106 BB� events collected at the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. The fractions of longitudinal polarization of the D?? states as well as partial wave fractions of the D1(2430)0 are obtained. We also set a 90% confidence level upper limit for the product of branching fractions of B(B�0?D?+b1(1235)-)�B(b1(1235)-???-). The measurements show evidence of nontrivial final-state interaction phases for the ?-meson-like amplitudes. � 2015 American Physical Society.

- Abstract
The process e+e-???cJ (J=1, 2) is studied via initial state radiation using 980fb-1 of data at and around the (nS) (n=1, 2, 3, 4, 5) resonances collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. No significant signal is observed except from ?(2S) decays. Upper limits on the cross sections between s=3.80 and 5.56 GeV are determined at the 90% credibility level, which range from a few pb to a few tens of pb. We also set upper limits on the decay rate of the vector charmonium [?(4040), ?(4160), and ?(4415)] and charmoniumlike [Y(4260), Y(4360), and Y(4660)] states to ??cJ. � 2015 American Physical Society.

We report the measurement of the direct CP asymmetry in the radiative B�?Xs+d? decay using a data sample of (772�11)�106 BB� pairs collected at the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. The CP asymmetry is measured as a function of the photon energy threshold. For E???2.1GeV, where E?? is the photon energy in the center-of-mass frame, we obtain ACP(B�?Xs+d?)=(2.2�3.9�0.9)%, consistent with the standard model prediction. � 2015 American Physical Society.

Using a sample of 771.6�106 ??(4S) decays collected by the Belle experiment at the KEKB e+e- collider, we observe, for the first time, the transition ?(4S)??hb(1P) with the branching fraction B[?(4S)??hb(1P)]=(2.18�0.11�0.18)�10-3 and we measure the hb(1P) mass Mhb(1P)=(9899.3�0.4�1.0)MeV/c2, corresponding to the hyperfine (HF) splitting ?MHF(1P)=(0.6�0.4�1.0)MeV/c2. Using the transition hb(1P)???b(1S), we measure the ?b(1S) mass M?b(1S)=(9400.7�1.7�1.6)MeV/c2, corresponding to ?MHF(1S)=(59.6�1.7�1.6)MeV/c2, the ?b(1S) width ??b(1S)=(8-5+6�5)MeV/c2 and the branching fraction B[hb(1P)???b(1S)]=(56�8�4)%. � 2015 American Physical Society.

- Abstract
We report the first observation of B0?X(3872)(K+?-) and evidence for B+?X(3872)(K0?+). We measure the product of branching fractions for the former to be B(B0?X(3872)(K+?-))�B(X(3872)?J/??+?-)=(7.9�1.3(stat)�0.4(syst))�10-6 and find that B0?X(3872)K?(892)0 does not dominate the B0?X(3872)K+?- decay mode. We also measure B(B+?X(3872)(K0?+))�B(X(3872)?J/??+?-)=(10.6�3.0(stat)�0.9(syst))�10-6. This study is based on the full data sample of 711fb-1 (772�106BB� pairs) collected at the ?(4S) resonance with the Belle detector at the KEKB collider. � 2015 American Physical Society.

We report a measurement of the time-dependent CP asymmetry of B[over ¯]^{0}→D_{CP}^{(*)}h^{0} decays, where the light neutral hadron h^{0} is a π^{0}, η, or ω meson, and the neutral D meson is reconstructed in the CP eigenstates K^{+}K^{-}, K_{S}^{0}π^{0}, or K_{S}^{0}ω. The measurement is performed combining the final data samples collected at the ϒ(4S) resonance by the BABAR and Belle experiments at the asymmetric-energy B factories PEP-II at SLAC and KEKB at KEK, respectively. The data samples contain (471±3)×10^{6} BB[over ¯] pairs recorded by the BABAR detector and (772±11)×10^{6} BB[over ¯] pairs recorded by the Belle detector. We measure the CP asymmetry parameters -η_{f}S=+0.66±0.10(stat)±0.06(syst) and C=-0.02±0.07(stat)±0.03(syst). These results correspond to the first observation of CP violation in B[over ¯]^{0}→D_{CP}^{(*)}h^{0} decays. The hypothesis of no mixing-induced CP violation is excluded in these decays at the level of 5.4 standard deviations.

- Abstract
We report improved measurements of the product branching fractions B(B+?D�0Ds0?+(2317))�B(Ds0?+(2317)?Ds+?0)=(8.0-1.2+1.3�1.1�0.4)�10-4 and B(B0?D-Ds0?+(2317))�B(Ds0?+(2317)?Ds+?0)=(10.2-1.2+1.3�1.0�0.4)�10-4, where the first errors are statistical, the second are systematic and the third are from D and Ds+ branching fractions. In addition, we report negative results from a search for hypothesized neutral (z0) and doubly charged (z++) isospin partners of the Ds0?+(2317) and provide upper limits on the product branching fractions B(B0?D0z0)�B(z0?Ds+?-) and B(B+?D0z++)�B(z++?Ds+?+) that are more than an order of magnitude smaller than theoretical expectations for the hypotheses that the Ds0?+(2317) is a member of an isospin triplet. The analysis uses a 711fb-1 data sample containing 772 million BB�-meson pairs collected at the ?(4S) resonance in the Belle detector at the KEKB collider. � 2015 American Physical Society.

- Abstract
We present a search for the rare leptonic decays B+?e+?e and B+??+??, using the full (4S) data sample of 772�106 BB� pairs collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. One of the B mesons from the (4S)?BB� decay is fully reconstructed in a hadronic mode, while the recoiling side is analyzed for the signal decay. We find no evidence of a signal in any of the decay modes. Upper limits of the corresponding branching fractions are determined as B(B+?e+?e)

Demographic, socio-economic, and political trends throughout the developed world have contrived to make elder care an issue of utmost policy importance. They also have led to sharp reductions in health and social program expenditures. Policymakers are looking to communities to help meet growing care needs because community care is believed to be better and cheaper than institutional care. However, these beliefs become untenable when costs beyond public sector costs are considered. In fact, informal care carries a number of hidden costs that seldom are considered in health and social policy discussions. This article introduces a taxonomy of the costs of informal elder care, which can be categorized as out-of-pocket expenditures, foregone employment opportunities, unpaid labor, and emotional, physical and social well-being costs. Then, an illustration is provided regarding how the taxonomy can be applied to understanding the incidence, magnitude, and distribution of these costs among stakeholder groups. This taxonomy can help inform ongoing debate about health and social policy reform., Fast, J.E., Williamson, D.L., and Keating, N.C. 1999. The hidden costs of informal elder care.

We observe D0-D? 0 mixing in the decay D0?K+? - using a data sample of integrated luminosity 976 fb-1 collected with the Belle detector at the KEKB e +e- asymmetric-energy collider. We measure the mixing parameters x? 2=(0.09�0.22)�10-3 and y?=(4.6�3.4)�10-3 and the ratio of doubly Cabibbo-suppressed to Cabibbo-favored decay rates RD=(3.53�0.13)�10-3, where the uncertainties are statistical and systematic combined. Our measurement excludes the no-mixing hypothesis at the 5.1 standard deviation level. � 2014 American Physical Society.

- Abstract
We present measurements of the masses and decay widths of the baryonic states ?c(2455)0/++ and ?c(2520)0/++ using a data sample corresponding to an integrated luminosity of 711fb-1 collected with the Belle detector at the KEKB e+e- asymmetric-energy collider operating at the (4S) resonance. We report the mass differences with respect to the ?c+ baryon M(?c(2455)0)-M(?c+)=167.29�0.01�0.02MeV/c2, M(?c(2455)++)-M(?c+)=167.51�0.01�0.02MeV/c2, M(?c(2520)0)-M(?c+)=231.98�0.11�0.04MeV/c2, M(?c(2520)++)-M(?c+)=231.99�0.10�0.02MeV/c2,and the decay widths ?(?c(2455)0)=1.76�0.04-0.21+0.09MeV/c2, ?(?c(2455)++)=1.84�0.04-0.20+0.07MeV/c2,?(? c(2520)0)=15.41�0.41-0.32+0.20MeV/c2,?(?c(2520)++)=14. 77�0.25-0.30+0.18MeV/c2,where the first uncertainties are statistical and the second are systematic. The isospin mass splittings are measured to be M(?c(2455)++)-M(?c(2455)0)=0.22�0.01�0.01MeV/c2 and M(?c(2520)++)-M(?c(2520)0)=0.01�0.15�0.03MeV/c2.

- Abstract
We report a measurement of D0-D?0 mixing parameters and a search for indirect CP violation through a time-dependent amplitude analysis of D0?KS0?+?- decays. The results are based on 921fb-1 of data accumulated with the Belle detector at the KEKB asymmetric-energy e+e- collider. Assuming CP conservation, we measure the mixing parameters x=(0.56�0.19- 0.09-0.09+0.03+0.06)% and y=(0.30�0.15-0.05-0.06+0.04+0.03)%, where the errors are statistical, experimental systematic, and systematic due to the amplitude model, respectively. With CP violation allowed, the parameters |q/p|=0.90-0.15-0.04-0.05+0.16+0.05+0.06 and arg(q/p)=(-6�11�3- 4+3)� are found to be consistent with conservation of CP symmetry in mixing and in the interference between mixing and decay, respectively. � 2014 American Physical Society.

- Abstract
We present a measurement of the branching fractions and charge-parity-(CP-)violating parameters in B??K decays. The results are obtained from the final data sample containing 772�106 BB? pairs collected at the ?(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We obtain the branching fractions B(B0??K0)=(4.5�0.4(stat)�0.3(syst))�10-6, B(B+??K+)=(6.8�0.4(stat)�0.4(syst))�10-6 which are in agreement with their respective current world averages. For the CP-violating parameters, we obtain A?KS0=-0.36�0.19(stat)�0. 05(syst),S?KS0=+0.91�0.32(stat)�0.05(syst),A?K+=-0. 03�0.04(stat)�0.01(syst), where A and S represent the direct and mixing-induced CP asymmetry, respectively. We find no evidence of CP violation in the decay channel B+??K+; however, we obtain the first evidence of CP violation in the B0??KS0 decay channel at the level of 3.1 standard deviations. � 2014 American Physical Society.

- Abstract
We report measurements of branching fractions of ? lepton decays to final states with a KS0 meson using a 669fb-1 data sample accumulated with the Belle detector at the KEKB asymmetric-energy e+e- collider. The inclusive branching fraction is measured to be B(?-?KS0X-??)=(9. 15�0.01�0.15)�10-3, where X- can be anything; the exclusive branching fractions are B(?-??-KS0??)=(4.16�0. 01�0.08)�10-3, B(?-?K-KS0??)=(7.40�0. 07�0.27)�10-4, B(?-??-KS0?0??)=(1. 93�0.02�0.07)�10-3, B(?-?K-KS0?0??)=(7. 48�0.10�0.37)�10-4, B(?-??-KS0KS0??)=(2. 33�0.03�0.09)�10-4, B(?-??-KS0KS0?0??) =(2.00�0.22�0.20)�10-5, where the first uncertainty is statistical and the second is systematic. For each mode, the accuracy is improved over that of pre-B-factory measurements by a factor ranging from five to ten. In ?-??-KS0KS0?0?? decays, clear signals for the intermediate states ?-??-f1(1285)?? and ?-?K*- KS0?0?? are observed. � 2014 American Physical Society.

- Abstract
Using data samples of 102�106 (1S) and 158�106 (2S) events collected with the Belle detector, a first experimental search has been made for double-charmonium production in the exclusive decays (1S,2S)?J/?(??)+X, where X=?c, ?cJ(J=0,1,2), ?c(2S), X(3940), and X(4160). No significant signal is observed in the spectra of the mass recoiling against the reconstructed J/? or ?? except for the evidence of ?c1 production with a significance of 4.6? for (1S)?J/?+?c1. The measured branching fraction B((1S)?J/?+?c1) is [3.90�1.21(stat)�0.23(syst)]�10-6. The 90% C.L. upper limits on the branching fractions of the other modes having a significance of less than 3? are determined. These results are consistent with theoretical calculations using the nonrelativistic QCD factorization approach. � 2014 American Physical Society.

- Abstract
We present a study of the branching fraction of the decay B0??0?0 and the fraction of longitudinally polarized ?0 mesons in this decay. The results are obtained from the final data sample containing 772�106 BB? pairs collected at the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We find 166�59 B0??0?0 events (including systematic uncertainties), corresponding to a branching fraction of B(B0??0?0)=(1.02�0.30(stat) �0.15(syst))�10-6 with a significance of 3.4 standard deviations and a longitudinal polarization fraction fL=0.21-0.22+0.18(stat)�0. 15(syst). We use the longitudinal polarization fraction to determine the Cabibbo-Kobayashi-Maskawa matrix angle ?2=(84.9�13.5)� through an isospin analysis in the B??? system. We furthermore find 125�41 B0?f0?0 events, corresponding to B(B0?f0?0) �B(f0??+?-)=(0.78�0.22(stat)�0.11(syst)) �10-6, with a significance of 3.1 standard deviations. We find no other significant contribution with the same final state, and set upper limits at 90% confidence level on the (product) branching fractions, B(B0??+?- ?+?-)

- Abstract
The cross sections of the processes e+e-?K+K-J/? and KS0KS0J/? are measured via initial state radiation at center-of-mass energies between the threshold and 6.0 GeV using a data sample of 980fb-1 collected with the Belle detector on or near the ?(nS) resonances, where n=1,2,...,5. The cross sections for e+e-?K+K-J/? are at a few pb level and the average cross section for e+e-?KS0KS0J/? is 1.8�0.6(stat)�0.3(syst)pb between 4.4 and 5.2 GeV. All of them are consistent with previously published results with improved precision. A search for resonant structures and associated intermediate states in the cross section of the process e+e-?K+K-J/? is performed. � 2014 American Physical Society.

- Abstract
We report a search for charmless hadronic decays of neutral B mesons to ??K?(892)0. The results are based on a 711fb-1 data sample that contains 772�106BB� pairs, collected at the (4S) resonance with the Belle detector at the KEKB asymmetric energy e+e- collider. We observe the decay for the first time with a significance of 5.0 standard deviations and obtain its branching fraction B[B0???K?(892)0]=[2.6�0.7(stat)�0.2(syst)]�10-6. We also measure the CP-violating asymmetry as ACP[B0???K?(892)0]=-0.22�0.29(stat)�0.07(syst). � 2014 American Physical Society.
