QCD factorization approach for rare decay
Nikolai Kivel
We present the estimate of the branching ratio for the rare decay . We use QCD factorization approach in order to compute the amplitude of the process. The calcul…

Breakdown of chiral expansion for parton distributions
N. Kivel, M. V. Polyakov
In the framework of the chiral perturbation theory we computed two- and three-loop corrections to the pion parton distributions which posses -function singularities at x->0. Thi…

Soft Pion Emission from the Nucleon Induced by Twist-2 Light-Cone Operators
N. Kivel, M. V. Polyakov, S. Stratmann
We compute the matrix elements for pion emission from the nucleon induced by twist-two light-cone operators in the kinematics where the pion is close to threshold. It is shown that…
