Search for the ηc2(1D) in e+e−→γηc2(1D) at √s near 10.6 GeV at Belle
(2021-07-27)
For the first time we search for the eta(c2) (1D) in e(+) e(-) -> gamma eta(c2)(1D) at root s = 10.52, 10.58, and 10.867 GeV with data samples of 89.5 fb(-1), 711 fb(-1), and 121.4 fb(-1), respectively, accumulated with ...
Measurement of Differential Branching Fractions of Inclusive B→Xuℓ+νℓ Decays
(American Physical Society, 2021-12-22)
The first measurements of differential branching fractions of inclusive semileptonic BX_{u}ℓ^{+}nu_{ℓ} decays are performed using the full Belle data set of 711fb^{-1} of integrated luminosity at the upsilon(4S) resonance ...
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 the Dark Photon in B-0 -> A ' A ', A ' -> e(+)e(-), mu(+)mu(-), and pi(+)pi(-) decays at Belle
(Springer, 2021-04-20)
We present a search for the dark photon A in the B-0 -> A ' A ' decays, where A ' subsequently decays to e(+)e(-), mu (+)mu (-), and pi (+)pi (-). The search is performed by analyzing 772 x 10(6)BB<overbar></mml:mover> ...
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 ...
First measurement of the Lambda(+)(c) -> p eta ' decay
(Springer, 2022)
[EN] We present the first measurement of the branching fraction of the singly Cabibbo-suppressed (SCS) decay Lambda(+)(c) -> p eta' with eta' -> eta pi(+)pi(-), using a data sample cor- responding to an integrated luminosity ...
Evidence for the decay Ω0c→π+Ω(2012)−→π+(¯KΞ)−
(American Physical Society, 2021-09-10)
Using a data sample of 980 fb(-1) collected with the Belle detector operating at the KEKB asymmetricenergy e(+)e(-) collider, we present evidence for the Omega(2012)-in the resonant substructure of Omega(0)(c) -> pi(+)(<(K)over ...
Measurement of the Tau Michel Parameters (Eta)Over-Bar and Xi Kappa in the Radiative Leptonic Decay Tau(-) -> L(-)Nu(Tau)(Nu)Over-Bar(L)Gamma
(Oxford University Press, 2018-02)
We present a measurement of the Michel parameters of the tau lepton, (eta) over bar and xi kappa, in the radiative leptonic decay tau(-) -> l(-)nu(tau)(nu) over bar (l)gamma using 711 fb(-1) of collision data collected ...
Search for B- -> mu(-)(nu)over-bar(mu) Decays at the Belle Experiment
(Amer Physical SOC, 2018-07-18)
We report the results of a search for the rare, purely leptonic decay B- -> mu(-)(nu) over bar (mu) performed with a 711 fb(-1) data sample that contains 772 x 10(6) B (B) over bar pairs, collected near the Upsilon(4S) ...
Observation of Υ(4S) → η1 Υ (1S)
(American Physical Society, 2018-08-06)
We report the first observation of the hadronic transition Upsilon(4S) -> eta'Upsilon(1S), using 496 fb(-1) data collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. ...
