Summing next-to-next-to-leading logarithms in b->c transitions at zero recoil
Andrey Grozin
Perturbative corrections to b->c transitions at zero recoil are considered in the two-step matching scheme. The matching coefficient for the b->c currents from the intermediate eff…
Lectures on QED and QCD
Andrey Grozin
The lectures are a practical introduction to perturbative calculations in QED and QCD. I discuss methods of calculation of one- and two-loop diagrams in dimensional regularization,…
Perturbative HQET
A. G. Grozin
Methods of calculation of loop diagrams in Heavy Quark Effective Theory (HQET) are presented.
Some topics in heavy-quark physics
A. G. Grozin
Some topics which can be easily explained to undergraduate students are presented, with elementary derivations. For a more systematic treatment of heavy-quark physics, see the text…
Complete analysis of polarization effects in gamma gamma <-> e+ e-
V. N. Baier, A. G. Grozin
Formulae for the cross section of the process gamma gamma <-> e+ e- with all four particles polarized are obtained in the lowest order of the perturbation theory using REDUCE.
Complete analysis of polarization effects in e gamma -> e gamma with REDUCE
A. G. Grozin
Formulae for the matrix element squared of the process e gamma -> e gamma with all four particles polarized are obtained using REDUCE.
