Measurements of the Branching Fractions of the Semileptonic Decays Xi(0)(c)-> Xi(-)l(+)nu(l) and the Asymmetry Parameter of Xi(0)(c) -> Xi(-)pi(+)
(American Physical Society, 2021-09-17)
Using data samples of 89.5 and 711 fb(-1) recorded at energies of root S = 10.52 and 10.58 GeV, respectively, with the Belle detector at the KEKB e(+)e(-) collider, we report measurements of branching fractions of semileptonic ...
Measurment of branching fractions and search for CP violation in D-0 -> pi(+)pi(-)eta, D-0 -> K+K-eta, and D-0 -> phi eta at Belle
(Springer, 2021-09-13)
We measure the branching fractions and CP asymmetries for the singly Cabibbo-suppressed decays D-0 -> pi(+)pi(-)eta, D-0 -> K+K-eta, and D-0 -> phi eta, using 980 fb(-1) of data from the Belle experiment at the KEKB e(+)e(-) ...
Measurements of branching fractions and asymmetry parameters of Xi(0)(c) -> Lambda(K)over-bar*(0), Xi(0)(c) -> Sigma(0)(K)over-bar*(0), and Xi(0)(c) -> Sigma(+) K*(-) decays at Belle
(Springer, 2021-06-28)
Using a data sample of 980 fb(-1) collected with the Belle detector at the KEKB asymmetric-energy e(+) e(-) collider, we study the processes of Xi(0)(c) -> Lambda(K) over bar*(0), Xi(0)(c) -> Sigma(0)(K) over bar*(0), and ...

(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> ...

(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
