Twist-3 contributions to $$\gamma \gamma \rightarrow \pi ^+\pi ^-,K^+K^-$$ γγ→π+π-,K+K- processes in perturbative QCD approach
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 studied with high precision at BELLE-II in the near fu...
