In this paper, we evaluate, up to QCD next-to-next-to-next-to-leading order, the Bc⁎ decay constant, which, within the nonrelativistic QCD (NRQCD) framework, is factorized as the product of the short-distance coefficient (SDC) and the long-distance

Abstract As one of the simplest hadronic processes, $$\gamma \gamma \rightarrow M^{+}M^{-}$$ γγ→M+M- ($$M=\pi ,K$$ M=π,K ) could be a good testing ground for our understanding of the perturbative and nonperturbative structure of QCD, and will be

Abstract We study the $$\gamma \gamma \rightarrow M^{+}M^{-}(M=\pi , K)$$ γ γ → M + M - ( M = π , K ) processes with the contributions from the two-particle twist-2 and twist-3 distribution amplitudes of pion and kaon mesons on BHL prescription

As one of the simplest hadronic processes, $\gamma\gamma\rightarrow M^{+}M^{-}$ ($M=\pi,K$) could be a good testing ground for our understanding of the perturbative and nonperturbative structure of QCD, and will be studied with high precision at BELL

Within the framework of nonrelativistic QCD factorization formalism, we compute the helicity amplitude as well as the decay width of ${\ensuremath{\eta}}_{Q2}$ ($Q=c$, $b$) electromagnetic decay into two photons up to next-to-next-to-leading order in

In this work, we calculate radiative vertex VPγ ( V = ϕ , ω , ρ and P = η , η ′ ) by utilizing ω – ϕ mixing scheme and taking into account the contributions of the three-particle twist-4 distribution amplitudes of the photon in QCD sum ru
