Small cosmological constant in seesaw mechanism with breaking down SUSY
V. V. Kiselev, S. A. Timofeev
The observed small value of cosmological constant can be naturally related with the scale of breaking down supersymmetry in agreement with other evaluations in particle physics.
B_c Decays and Lifetime in QCD Sum Rules
V. V. Kiselev, A. E. Kovalsky, A. K. Likhoded
In the framework of three-point QCD sum rules, the form factors for the semileptonic decays of B_c --> B_s(B_s^*) l νare calculated with account for the Coulomb-like alpha_s/v-corr…
Semileptonic B_c-meson decays in sum rules of QCD and NRQCD
V. V. Kiselev, A. K. Likhoded, A. I. Onishchenko
The semileptonic B_c-meson decays into the heavy quarkonia J/ψ(η_c) and a pair of leptons are investigated in the framework of three-point sum rules of QCD and NRQCD. Calculations…
Lifetimes of doubly charmed baryons: and
V. V. Kiselev, A. K. Likhoded, A. I. Onishchenko
We have performed a detailed investigation of total lifetimes for the and baryons in the framework of operator product expansion over the inverse mass of…
Doubly Charmed Baryon Production in Hadronic Experiments
A. V. Berezhnoy, V. V. Kiselev, A. K. Likhoded +1
In the leading order of perturbative QCD one calculates the total and differential cross-sections for the hadronic production of doubly charmed baryons and in d…
Photonic production of P-wave states of B_c mesons
A. V. Berezhnoy, V. V. Kiselev, A. K. Likhoded
Numerical calculations for the production of -wave levels of quarkonium in collisions are performed in the leading order of perturbation theory. Th…
