QCD Calculation of the $B \to π, K$ Form Factors

V. M. Belyaev, A. Khodjamirian, R. Rückl

We calculate the form factors for the heavy-to-light transitions $B \to π, K$ by means of QCD sum rules using $π$ and $K$ light-cone wave functions. Higher twist contributio…

Soft Modes Contribution into Path Integral

V. M. Belyaev

A method for nonperturbative path integral calculation is proposed. Quantum mechanics as a simplest example of a quantum field theory is considered. All modes are decomposed into h…

Delta-Isobar Magnetic Form Factor in QCD

V. M. Belyaev

We consider the QCD sum rules approach for Delta-isobar magnetic form factor in the infra-red region $0 < Q^{2} < 1 G e V^{2}$ . The QCD sum rules in external variable field are used. The obta…
