Renormalization group improvement of truncated perturbative series in QCD. Decays of tau-lepton and eta_c-charmonium
V. V. Kiselev
We formulate a general scheme to improve the truncated perturbative expansion in alpha_s by means of the renormalization group in QCD for the single-scale quantities. The procedure…
Contributions of leptoquark interactions into the tensor and scalar form factors of K to pi l nu_l decay
V. V. Kiselev, A. K. Likhoded, V. F. Obraztsov
In the framework of scalar-vector dominance we calculate the hadronic matrix elements of scalar and tensor effective quark currents induced by virtual leptoquark interactions. Comb…
New Insight into the Photoproduction of D-star meson in QCD
A. V. Berezhnoy, V. V. Kiselev, A. K. Likhoded
In the framework of the model motivated by perturbative calculations in the fourth -order, the estimates for the cross-section of the -meson production in the…
Two-loop anomalous dimensions for currents of baryons with two heavy quarks in NRQCD
V. V. Kiselev, A. I. Onishchenko
We present analytical results on the two-loop anomalous dimensions of currents for baryons, containing two heavy quarks with arbitrary Dirac matri…
Theoretical status of the B_c meson
S. S. Gershtein, V. V. Kiselev, A. K. Likhoded +3
Theoretical predictions on the meson properties are reviewed.
Nonabelian Nature of Asymmetry for the Meson Production in Gluon-Photon Interaction
A. V. Berezhnoy, V. V. Kiselev, A. K. Likhoded
Calculations of cross-sections for the gluon-photon production of and mesons as well as for the production in -interactions at HERA are performed in the leading o…
