An improved search for the electric dipole moment of the τ lepton
(Springer, 2022-04-20)
We report a measurement of the electric dipole moment of the tau lepton (d(tau)) using an 833 fb(-1) data sample collected near the Upsilon(4S) resonance, with the Belle detector at the KEKB asymmetric-energy e(+)e(-) ...
Search for a Light Higgs Boson in Single-Photon Decays of Upsilon(1S) Using Upsilon(2S) -> pi(+) pi(-) Upsilon(1S) Tagging Method
(American Physical Society, 2022)
[EN] We search for a light Higgs boson (A(0)) decaying into a tau(+)tau(-) or mu(+)mu(-) pair in the radiative decays of Upsilon(1S). The production of Upsilon(1S) mesons is tagged by Upsilon(2S) -> pi(+)pi(-)Upsilon(1S) ...
Measurements of partial branching fractions of inclusive B -> XTI4PFTI4PF(u)(lx+)nu(l) decays with hadronic tagging
(American Physical Society, 2021-07-12)
We present measurements of partial branching fractions of inclusive semileptonic B -> X(u)l+nu(l) decays using the full Belle dataset of 711 fb(-1) of integrated luminosity at the gamma(4S) resonance and for l = e, mu. ...
Measurement of Two-Particle Correlations of Hadrons in e^{+}e^{-} Collisions at Belle.
(American Physical Society, 2022)
[EN] The measurement of two-particle angular correlation functions in high-multiplicity e^{+}e^{-} collisions at sqrt[s]=10.52GeV is reported. In this study, the 89.5fb^{-1} of hadronic e^{+}e^{-} annihilation data collected ...
Measurements of the branching fractions of Ξ0c→ΛK0S, Ξ0c→Σ0K0S, and Ξ0c→Σ+K− decays at Belle
(American Physical Society, 2022)
[EN] Using the entire data sample of 980 fb(-1) collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider, we present measurements of the branching fractions of the Cabibbo-favored decays Xi c(0) ...
Search for the decay B0s→ηη
(American Physical Society, 2022)
[EN] We report results from a search for the decay B-s(0) -> eta eta using 121.4 fb(-1) of data collected at the Upsilon(5S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We do not ...
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 ...
Measurement of Branching Fractions of Delta(+)(c) -> eta Lambda pi(+), eta Sigma(0)pi(+), Lambda(1670)pi(+), and eta Sigma(1385)(+)
(American Physical Society, 2021-03-15)
We report branching fraction measurements of four decay modes of the Lambda(+)(c) baryon, each of which includes an eta meson and a Lambda baryon in the final state, and all of which are measured relative to the Lambda(+)(c) ...
Measurements of the Branching Fractions of the Semileptonic Decays Xi(0)(c)-> Xi(-)l(+)nu(l) and the Asymmetry Parameter of Xi(0)(c) -> Xi(-)pi(+)
(American Physical Society, 2021-09-17)
Using data samples of 89.5 and 711 fb(-1) recorded at energies of root S = 10.52 and 10.58 GeV, respectively, with the Belle detector at the KEKB e(+)e(-) collider, we report measurements of branching fractions of semileptonic ...
