Transition form factors $γ^{} γ \to η$ and $γ^{} γ \to η^{'}$ in QCD

S. S. Agaev, V. M. Braun, N. Offen +2

We update the theoretical framework for the QCD calculation of transition form factors $γ^{*} γ \to η$ and $γ^{*} γ \to η^{'}$ at large photon virtualities including full next-to-leading order…

Light-Cone Sum Rules for the $D_{(s)} \to η^{(')} l ν_{l}$ Form Factor

N. Offen, F. A. Porkert, A. Schafer

We present an improved light-cone sum rule analysis of the decay form factors of $D$ and $D_{s}$ into $η$ and $η^{'}$ and argue that these decays offer a very promissing possibi…

BELLE Data on the $π^{0} γ * γ$ Form Factor: A Game Changer?

S. S. Agaev, V. M. Braun, N. Offen +1

We extend our analysis of the $π^{0} γ^{*} γ$ form factor by including a comparison with the new BELLE data. The necessity of new precision measurements in a broad interval of momentum t…

Light Cone Sum Rules for the pi0-gamma*-gamma Form Factor Revisited

S. S. Agaev, V. M. Braun, N. Offen +1

We provide a theoretical update of the calculations of the pi0-gamma*-gamma form factor in the LCSR framework, including up to six polynomials in the conformal expansion of the pio…
