Measurement of the resonant and nonresonant branching ratios in Xi(0)(c) -> Xi K-0(+) K-
(American Physical Society, 2021-06-03)
Using the entire data sample of 980 fb(-1) integrated luminosity collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider, we present an amplitude analysis measuring the branching fractions of the ...
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 ...
Update of inclusive cross sections of single and pairs of identified light charged hadrons
(American Physical Society, 2020-05-13)
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 ...
Study of Electromagnetic Decays of Orbitally Excited Xi(C) Baryons
(American Physical Society, 2020-10-26)
Using 980 fb(-1) of data collected with the Belle detector operating at the KEKB asymmetric-energy e(+) e(-) collider, we report a study of the electromagnetic decays of excited charmed baryons Xi(c)(2790) and Xi(c)(2815). ...
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) ...
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 ...
