A novel way to probe distribution amplitudes of neutral mesons in e^+e^- annihilation
N. A. Kivel, M. V. Polyakov
We derive the amplitude for the process at large invariant energy. The process goes through the two-photon exchange and its amplitude is expressed in terms of th…

Two-photon exchange in elastic electron-proton scattering : QCD factorization approach
Nikolai Kivel, Marc Vanderhaeghen
We estimate the two-photon exchange contribution to elastic electron-proton scattering at large momentum transfer . It is shown that the leading two-photon exchange amplitude…

Leading Chiral Logarithms for Pion Form Factors to Arbitrary Number of Loops
N. A. Kivel, M. V. Polyakov, A. A. Vladimirov
We develop the method of calculation of the leading chiral (infrared) logarithms to an arbitrary loop order for various form factors of Nambu-Goldstone bosons. The method is illust…
