Data on $J/\Psi \to \gamma (\rho\rho)$ demand a broad $0^-$ $\rho\rho$ signal, attributable to a glueball with a mass of 1750--2100 MeV. Decays of this broad state to $\rho\rho$, $\omega\omega$, $K^*\bar K^*$ and $\phi \phi$ channels agree well with flavour blindness. The narrow $\iota(1440)$ may be attributed to mixin...

The branching ratio and direct $CP$ asymmetry of the ${\Upsilon}(1S)$ ${\to}$ $B_{c}D_{s}$ weak decay are estimated with the perturbative QCD approach. It is found that (1) The direct $CP$-violating asymmetry is close to zero. (2) the branching ratio ${\cal B}r({\Upsilon}(1S){\to}B_{c}D_{s})$ ${\gtrsim}$ $10^{-10}$ mig...

We present in this talk recent results of the vector and axial-vector transitions of the nucleon to the pentaquark baryon Theta^{+}, based on the SU(3) chiral quark-soliton model. The results are summarized as follows: K^{*}-N-Theta vector and tensor coupling constants turn out to be g_{K^{*}N Theta} = 0.81 and f_{K^...

We discuss the correlations of charming penguin contributions to $B\to\pi\pi$, $\pi K$ and KK using approximate flavor SU(3) symmetry. Strong constraints are found from the direct CP asymmetries especially in $\pi K$ modes. We make a global fit to the latest data and find that only a small charming penguin is allowed...
