Monopole, gluino and charge condensates in gauge theories with broken N=2 supersymmetry
Arkady Vainshtein
We consider chiral condensates in SU(2) gauge theory with broken N=2 supersymmetry and one fundamental flavor in the matter sector. Matter and gaugino condensates are determined by…
Heavy flavor decays and OPE in two-dimensional 't Hooft model
Arkady Vainshtein
The 't Hooft model (two-dimensional QCD in the limit of large number of colors) is used as a testground for calculations of nonleptonic and semileptonic inclusive widths of heavy f…
HQET and Semileptonic Form Factors
Arkady Vainshtein
(Contribution to Proceedings of the Seventh International Symposium On Heavy Flavor Physics, July 7-11, 1997, Santa Barbara.) Theoretical approaches to form factors of semileptonic…
Review of Selected Topics in HQET
Arkady Vainshtein
A few topics on the expansion in heavy quark mass are discussed. The theoretical framework is the Wilson Operator Product Expansion rather than the Heavy Quark Effective Theory.
