We report the first observation of the radiative decay of the Upsilon(1S) into a charmonium state. The significance of the observed signal of Upsilon(1S) -> gamma chi(c1) is 6.3 standard deviations including systematics. ...

The experimental results on the ratios of branching fractions R(D) = B((B) over bar -> D tau(-)(nu) over bar (tau))/B((B) over bar -> Dl(-)(nu) over bar (e)) and R(D*) = B((B) over bar -> D*tau(-)(nu) over bar (tau))/B((B) ...

We report the measurement of e(+) e(-) -> D-s(+) Ds(2)*(2573)(-) c.c. via initial-state radiation using a data sample of an integrated luminosity of 921.9 fb(-1) collected with the Belle detector at the Upsilon(4S) and ...

The experimental results on the ratios of branching fractions R(D) = B((B) over bar -> D tau(-)(nu) over bar (tau))/B((B) over bar -> Dl(-)(nu) over bar (e)) and R(D*) = B((B) over bar -> D*tau(-)(nu) over bar (tau))/B((B) ...

We report new measurements of the production cross sections of pairs of charged pions and kaons as a function of their fractional energies using various fractional-energy definitions. Two different fractional-energy ...

The first dedicated search for the ηc2(1D) is carried out using the decays B+→ ηc2(1D)K+, B0 → ηc2(1D)K0S, B0→ ηc2(1D)π−K+, and B+→ ηc2(1D)π+K0S with ηc2(1D) → hcγ. No significant signal is found. For the ηc2(1D) mass range ...

[EN] We present the results of the first Dalitz plot analysis of the decay D0 → K−πþη. The analysis is performed on a data set corresponding to an integrated luminosity of 953 fb−1 collected by the Belle detector at the ...

We report searches for B0→invisible and B0→invisible+γ decays, where the energy of the photon is required to be larger than 0.5 GeV. These results are obtained from a 711  fb−1 data sample that contains 772×106B¯B pairs ...
