The nature of $$Z_b$$ Z b states from a combined analysis of $$\Upsilon (5S)\rightarrow h_b(mP) \pi ^+ \pi ^-$$ Υ ( 5 S ) → h b ( m P ) π + π - and $$\Upsilon (5S)\rightarrow B^{(*)}\bar{B}^{(*)}\pi $$ Υ ( 5 S ) → B ( ∗ ) B ¯ ( ∗ ) π

Violation through Correlations in B → πK , B d → π + π − , B s → K + K − Observable Space

We investigate allowed regions in observable space of B → πK, Bd → ππ and Bs → KK decays, characterizing these modes in the Standard Model. After a discussion of a new kind of contour plots for the B → πK system, we focus on the mixing-induced and direct CP asymmetries of the decays Bd → ππ and Bs → KK. Using experimental information on the CP-averaged Bd → πK and Bd → ππ branching ratios, the ...

The Anomalous Υ(1s)π+π− and Υ(2s)π+π− Production near the Υ(5s) Resonance

We report the study of ee → Υ(1S)ππ, Υ(2S)ππ, Υ(3S)ππ, and Υ(1S)KK, near the peak of the Υ(5S) resonance. The results are based on a data sample of 21.7 fb collected with the Belle detector at the KEKB ee collider. Attributing the signals to the Υ(5S) resonance, the partial widths Γ(Υ(5S) → Υ(1S)ππ) = 0.59± 0.04(stat)± 0.09(syst) MeV and Γ(Υ(5S) → Υ(2S)ππ) = 0.85 ± 0.07(stat) ± 0.16(syst) MeV a...
