$Z \to π^{+} π^{-}, K^{+} K^{-}$ : A touchstone of the PQCD approach

Shan Cheng, Qin Qin

We study two rare decays, $Z \to π^{+} π^{-}$ and $K^{+} K^{-}$ , in the perturbative QCD approach up to the next-to-leading order of the strong coupling and the leading power of $1/ m_{Z}$ , $m_…

Rho-pion transition form factors in the $k_{T}$ factorization formulism revisited

Jun Hua, Shan Cheng, Ya-lan Zhang +1

We revisit the evaluations for the spacelike and timelike $ρ π$ transition form factors $F_{ρ π} (Q^{2})$ and $G_{ρ π} (Q^{2})$ with the inclusion of the the next-to-leading order (NLO) QCD…
