Test of semi-local duality in a large $N_{C}$ framework

Ling-Yun Dai, Xian-Wei Kang, Ulf-G. Meißner

In this paper we test the semi-local duality based on the method of Ref.[1] for calculating final-state interactions at varying number of colors ( $N_{C}$ ). We compute the amplitudes…

Semileptonic $B$ and $B_{s}$ decays involving scalar and axial-vector mesons

Xian-Wei Kang, Tao Luo, Yi Zhang +2

We report our theoretical calculations on the branching fractions for the semileptonic $B$ and $B_{s}$ decays, i.e., $B (B_{s}) \to (P, V, S, A) ℓ ν_{ℓ}$ , where $P$ and $V$ de…

$J / ψ \to γ η^{'} π^{+} π^{-}$ and the structure observed around the $p ˉ p$ threshold

Ling-Yun Dai, Johann Haidenbauer, Ulf-G. Meißner

We analyze the origin of the structure observed in the reaction $J / ψ \to γ η^{'} π^{+} π^{-}$ for $η^{'} π^{+} π^{-}$ invariant masses close to the antiproton-proton ( $p ˉ p$ ) threshold, commonly as…
