Li Y, Shen C, Yuan C, Adachi I, Aihara H, Al Said S, et al.
Phys Rev Lett . 2019 Apr; 122(8):082001. PMID: 30932568
We present the first measurements of absolute branching fractions of Ξ_{c}^{0} decays into Ξ^{-}π^{+}, ΛK^{-}π^{+}, and pK^{-}K^{-}π^{+} final states. The measurements are made using a dataset comprising (772±11)×10^{6} BB[over ¯]...

Phys Rev Lett . 2019 Mar; 122(7):072501. PMID: 30848612
We report the first observation of the double strange baryon Ξ(1620)^{0} in its decay to Ξ^{-}π^{+} via Ξ_{c}^{+}→Ξ^{-}π^{+}π^{+} decays based on a 980  fb^{-1} data sample collected with the Belle...

Guan Y, Vossen A, Adachi I, Adamczyk K, Ahn J, Aihara H, et al.
Phys Rev Lett . 2019 Feb; 122(4):042001. PMID: 30768311
We report the first observation of the spontaneous polarization of Λ and Λ[over ¯] hyperons transverse to the production plane in e^{+}e^{-} annihilation, which is attributed to the effect arising...

Adachi I, Adye T, Ahmed H, Ahn J, Aihara H, Akar S, et al.
Phys Rev Lett . 2019 Jan; 121(26):261801. PMID: 30636113
We present first evidence that the cosine of the CP-violating weak phase 2β is positive, and hence exclude trigonometric multifold solutions of the Cabibbo-Kobayashi-Maskawa (CKM) Unitarity Triangle using a time-dependent...

Phys Rev Lett . 2018 Dec; 121(23):232001. PMID: 30576207
We report the observation of ϒ(2S)→γη_{b}(1S) decay based on an analysis of the inclusive photon spectrum of 24.7  fb^{-1} of e^{+}e^{-} collisions at the ϒ(2S) center-of-mass energy collected with the...

Phys Rev Lett . 2018 Aug; 121(5):052003. PMID: 30118260
Using data recorded with the Belle detector, we observe a new excited hyperon, an Ω^{*-} candidate decaying into Ξ^{0}K^{-} and Ξ^{-}K_{S}^{0} with a mass of 2012.4±0.7(stat)±0.6(syst)  MeV/c^{2} and a width...

We report the results of a search for the rare, purely leptonic decay B^{-}→μ^{-}ν[over ¯]_{μ} performed with a 711  fb^{-1} data sample that contains 772×10^{6}  BB[over ¯] pairs, collected near...

We report the first evidence for isospin violation in B→K^{*}γ and the first measurement of the difference of CP asymmetries between B^{+}→K^{*+}γ and B^{0}→K^{*0}γ. This analysis is based on the...
