Measurement of B(Bs→DsX) with Bs semileptonic tagging
(American Physical Society, 2022)
[EN] We report the first direct measurement of the inclusive branching fraction B(B-s -> DsX) via B-s tagging in e(+)e(-) -> gamma(5S) events. Tagging is accomplished through a partial reconstruction of semileptonic decays ...
Combined analysis of Belle and Belle II data to determine the CKM angle phi(3) using B+ -> D(K(S)(0)h(+)h(-))h(+) decays
(Springer, 2022)
[EN] We present a measurement of the Cabibbo-Kobayashi-Maskawa unitarity triangle angle phi(3) (also known as gamma) using a model-independent Dalitz plot analysis of B+ -> D(K(S)(0)h(+)h(-))h(+), where D is either a D-0 ...
Search for tetraquark states X-ccss in D-s(+) D-s(+) (D-s*(+) D-s*(+)) final states at Belle
(American Physical Society, 2022-02-01)
[EN] A search for double-heavy tetraquark state candidates Xcc (x) over bar(s) over bar decaying to Ds+Ds+ and D-s*+D-s(*)+ is presented for the first time using the data samples of 102 x 106 Gamma and 158 x 10(6) Gamma(2S) ...
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) ...
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 ...
Study of ¯B0→D+h−(h=K/π) decays at Belle
(American Physical Society, 2022)
[EN] We present a measurement of the branching fractions of the Cabibbo favored (B) over bar (0) -> D+pi(-) and the Cabibbo suppressed (B) over bar (0) -> D+K- decays. We find B((B) over bar (0) -> D+pi(-)) = (2.48 +/- ...
Search for B0 meson decays into Λ and missing energy with a hadronic tagging method at Belle
(American Physical Society, 2022)
[EN] We present a search for the decays of B-0 mesons into a final state containing a Lambda baryon and missing energy. These results are obtained from a 711 fb(-1) data sample that contains 772 x 10(6) B (B) over bar pairs ...
