QCD factorization approach for rare $B ˉ^{0} \to D^{*} γ$ decay

Nikolai Kivel

We present the estimate of the branching ratio for the rare decay $B ˉ^{0} \to D^{*} γ$ . 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 $δ$ -function singularities at x->0. Thi…
