3. Observation of Transverse Λ/Λ¯ Hyperon Polarization in e+e Annihilation at Belle / Guan, Y. ; Vossen, A. ; Adachi, I. ; Adamczyk, K. ; et al
We report the first observation of the spontaneous polarization of Λ and Λ¯ hyperons transverse to the production plane in e+e annihilation, which is attributed to the effect arising from a polarizing fragmentation function. [...]

6. First Evidence for cos2β>0 and Resolution of the Cabibbo-Kobayashi-Maskawa Quark-Mixing Unitarity Triangle Ambiguity / Adachi, I. ; Adye, T. ; Ahmed, H. ; Ahn, J. K. ; et al
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 Dalitz plot analysis of B0D(*)h0 with DKS0π+π decays, where h0{π0,η,ω} denotes a light unflavored and neutral hadron. [...]

We report measurements of sin2β and cos2β using a time-dependent Dalitz plot analysis of B0D(*)h0 with DKS0π+π decays, where the light unflavored and neutral hadron h0 is a π0, η, or ω meson. [...]
