Measurement of branching fraction and final-state asymmetry for the (B)over-bar(0) -> (KSK -/+)-K-0 pi(+/-) decay
(American Physical Society, 2019-07-10)
We report a measurement of the branching fraction and final-state asymmetry for the (B) over bar -> (KSK -/+)-K-0 pi(+/-) decays. The analysis is based on a data sample of 711 fb(-1) collected at the gamma(4S) resonance ...
Observation of a new structure near 10.75 GeV in the energy dependence of the e+e−→ ϒ (nS)π+π− (n = 1, 2, 3) cross sections
(Springer, 2019-10-22)
We report a new measurement of the e(+)e(-)-> Upsilon(nS)pi(+)pi(-) (n = 1, 2, 3) cross sections at energies from 10.52 to 11.02 GeV using data collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) ...
Beam-helicity asymmetries for single-hadron production in semi-inclusive deep-inelastic scattering from unpolarized hydrogen and deuterium targets
(Elsevier, 2019-10-10)
A measurement of beam-helicity asymmetries for single-hadron production in deep-inelastic scattering is presented. Data from the scattering of 27.6 GeV electrons and positrons off gaseous hydrogen and deuterium targets ...
Measurement of the CKM matrix element vertical bar V-cb vertical bar from B-0 -> D*(-)l(+)nu(l) at Belle
(American Physical Society, 2019-09-11)
We present a new measurement of the Cabibbo-Kobayashi-Maskawa matrix element vertical bar V-cb vertical bar from B-0 -> D*(-)l(+)nu(l) decays, reconstructed with the full Belle data set of 711 fb(-1) integrated luminosity. ...
First search for the ηc2(1D) in B decays at Belle
(Springer, 2020-05-08)
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 ...
Observation of the Radiative Decays of Υ(1S) to χc1
(American Physical Society, 2020-03-26)
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. ...
Dalitz analysis of D0 → K− π+ η decays at Belle
(American Physical Society, 2020-07-06)
[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 ...
Search for B0 decays to invisible final states ( + γ) at Belle
(American Physical Society, 2020-07-08)
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 ...
