Ratios of Hidden-Charm Compact Pentaquark Decay Widths in Quark-Diquark Model

Alexandra A. Dobrynina, Alexander Ya. Parkhomenko, Alexey V. Zinchenko

A number of resonances comparable with a hypothesis of hidden-charm pentaquark is observed by the LHCb Collaboration. We interpret these narrow resonances as compact hidden-charm d…

The $η^{'} g^{} g^{()}$ Vertex Including the $η^{'}$ -Meson Mass

A. Ali, A. Ya. Parkhomenko

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

Branching Ratios for $B \to K^{*} γ$ and $B \to ρ γ$ Decays in Next-to-Leading Order in the Large Eneregy Effective Theory

A. Ali, A. Ya. Parkhomenko

We calculate the so-called hard spectator corrections in $O (α_{s})$ in the leading-twist approximation to the decay widths for $B \to K^{*} γ$ and $B \to ρ γ$ decays and their…

The $η^{'} g^{} g^{}$ vertex with arbitrary gluon virtualities in the perturbative QCD hard scattering approach

A. Ali, A. Ya. Parkhomenko

We study the $η^{'} g^{*} g^{*}$ vertex for arbitrary gluon virtualities in the time-like and space-like regions, using the perturbative QCD hard scattering approach and an input wa…
