1. Observation of Ξ(1620)0 and Evidence for Ξ(1690)0 in Ξc+Ξπ+π+ Decays / Sumihama, M. ; Adachi, I. ; Ahn, J. K. ; Aihara, H. ; et al
We report the first observation of the double strange baryon Ξ(1620)0 in its decay to Ξπ+ via Ξc+Ξπ+π+ decays based on a 980 fb1 data sample collected with the Belle detector at the KEKB asymmetric-energy e+e collider. [...]

2. Measurements of branching fraction and direct CP asymmetry in B±KS0KS0K± and a search for B±KS0KS0π± / Kaliyar, A. B. ; Behera, P. ; Mohanty, G. B. ; Gaur, V. ; et al
We study charmless hadronic decays of charged B mesons to the final states KS0KS0K± and KS0KS0π± using a 711 fb1 data sample that contains 772×106 BB¯ pairs and was collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e collider. [...]

4. 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. [...]
