The $η^{'} g^{} g^{()}$ Vertex Function in Perturbative QCD and $η^{'}$ -Meson Mass Effects

A. Ali, A. Ya. Parkhomenko

The $η^{'} g^{*} g^{(*)}$ effective vertex function (EVF) is calculated in the QCD hard-scattering approach, taking into account the $η^{'}$ -meson mass. We work in the approxim…

$B \to ρ γ$ Decay in the Large Energy Effective Theory

Alexander Ya. Parkhomenko

The branching ratio for the $B \to ρ γ$ decay in the next-to-leading order (NLO) in the strong coupling $α_{s}$ and in leading power in $Λ_{QCD} / m_{B}$ is presented. The corrections…

The Effective $η^{'} g^{} g^{}$ Vertex at Arbitrary Gluon Virtualities

A. Ali, A. Ya. Parkhomenko

The effective $η^{'} g^{*} g^{*}$ vertex is studied in the standard (Brodsky-Lepage) and modified hard scattering approaches for arbitrary gluon virtualities in the time-like and sp…
