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) ...
Cubic 3D Chern photonic insulators with orientable large Chern vectors
(Nature Research, 2021-12-17)
[EN]Chern number controls the number of surface state channels in topological insulators. Here the authors propose 3D Chern insulating cubic photonic crystals with orientable and arbitrarily large Chern numbers demonstrating ...
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. ...
Cubic Hall viscosity in three-dimensional topological semimetals
(American Physical Society, 2021-09-16)
The nondissipative (Hall) viscosity is known to play an interesting role in two-dimensional (2D) topological states of matter, in the hydrodynamic regime of correlated materials, and in classical active fluids with broken ...
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 ...
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) ...
