Measurements of the Branching Fractions of Lambda(+)(c) -> p eta and Lambda(+)(c) -> p pi(0) Decays at Belle
(American Physical Society, 2021-04-14)
We report measurements of the branching fractions of singly Cabibbo-suppressed decays Lambda(+)(c) -> p eta and Lambda(+)(c) -> p pi(0) using the full Belle data sample corresponding to an integrated luminosity of 980.6 ...
Search for B-s(0) -> eta'Xs(s)over-bar at Belle using a semi-inclusive method
(American Physical Society, 2021-07-12)
We report the first search for the penguin-dominated process B-s(0) -> eta'X(s ()s() over bar) using a semi-inclusive method. A 121.4 fb-1 integrated luminosity gamma(5S) data set collected by the Belle experiment, at the ...
Phase transitions of alkaline-earth metal sulfides under pressure
(IOP Publishing Ltd., 2021-06-21)
[EN] Wehave systematically explored the crystal structures of alkaline-earth metal sulfides under pressure
by using a swarm-intelligence structural prediction method. At low pressures we successfully
reproduced their ...
Nanoscale shear cohesion between cement hydrates: The role of water diffusivity under structural and electrostatic confinement
(Elsevier, 2022-04)
[EN] The calcium silicate hydrate (C-S-H) controls most of the final properties of the cement paste, including its mechanical performance. It is agreed that the nanometer-sized building blocks that compose the C-S-H are ...
Test of Lepton Flavor Universality and Search for Lepton Flavor Violation in B -> Kll Decays
(Springer, 2021-03-10)
We present measurements of the branching fractions for the decays B -> K mu(+)mu(-) and B -> Ke(+)e(-), and their ratio (R-K), using a data sample of 711 fb(-1) that contains 772 x 10(6) B (B) over bar events. The data ...
Measurement of the energy dependence of the e(+) e(-) -> B(B)over-bar, B (B)over-bar* and B*(B)over-bar* exclusive cross sections
(Springer, 2021-06-23)
We report the first measurement of the exclusive cross sections e(+) e(-) -> B (B) over bar, e(+) e(-) -> B (B) over bar*, and e(+) e(-) -> B* (B) over bar* in the energy range from 10.63 GeV to 11.02 GeV. The B mesons are ...
Measurement of branching fractions and CP asymmetries for D-s(+) -> K+ (eta, pi(0)) and D-s(+) -> pi(+) (eta,pi(0)) decays at Belle
(American Physical Society, 2021-06-09)
We report measurements of the branching fractions and CP asymmetries for D-s(+) -> K+eta, D-s(+) -> K+ pi(0), and D-s(+) -> pi(+)eta decays, and the branching fraction for D-s(+) -> pi+pi(0). Our results are based on a ...
First determination of the spin and parity of the charmed-strange baryon Xi(c) (2970)(+)
(American Physical Society, 2021-06-16)
We report results from a study of the spin and parity of Xi(c)(2970)(+) using a 980 fb(-1) data sample collected by the Belle detector at the KEKB asymmetric-energy e(+) e(-) collider. The decay angle distributions in the ...
Coexistence of Superconductivity and Spin-Splitting Fields in Superconductor/Ferromagnetic Insulator Bilayers of Arbitrary Thickness
(American Physical Society, 2021-05-19)
Ferromagnetic insulators (FI) can induce a strong exchange field in an adjacent superconductor (S) via the magnetic proximity effect. This manifests as spin splitting of the BCS density of states of the superconductor, an ...
Measurement of the Charm-Mixing Parameter y(CP) in D-0 -> K-S(0)Omega Decays at Belle
(American Physical Society, 2020-10-19)
We report the first measurement of the charm-mixing parameter y(CP) in D-0 decays to the CP-odd final state K-S(0 omega). The study uses the full Belle e(+)e(-) annihilation data sample of 976 fb(-1) taken at or near the ...
