Exceptional solutions to the Bethe ansatz equations
- L. Avdeev, A. Vladimirov
- Physics
- 1 November 1986
The properties of some special solutions of the equations of the Bethe ansatz are investigated. Examples of nontrivial Bethe vectors corresponding to solutions with equal values of the spectral… Expand
A queer reduction of degrees of freedom
- L. Avdeev, M.V.Chizhov
- Physics
- 13 July 1994
The classical dynamics of antisymmetric second-rank tensor matter fields is analyzed. The conformally invariant action for the tensor field leads to a positive-definite hamiltonian on the class of… Expand
Renormalizations in supersymmetric and nonsupersymmetric non-abelian Chern-Simons field theories with matter
- L. Avdeev, D. Kazakov, I. Kondrashuk
- Physics
- 15 February 1993
Abstract We explicitly carry out the renormalization of non-abelian Chern-Simons field theories with matter in (2 + 1) dimensions. All the renormalization constants are calculated to the leading… Expand
Renormalizations in abelian Chern-Simons field theories with matter
- L. Avdeev, G. V. Grigoryev, D. Kazakov
- Physics
- 14 September 1992
Abstract We consider renormalizations in D = 3 abelian Chern-Simons field theories with matter. The anomalous dimensions and β-functions in a general renormalizable theory with the global SU( n )… Expand
O (aas2) correction to the electroweak ? parameter
- L. Avdeev, J. Fleischer, S. Mikhailov, O. Tarasov
- Physics
- 22 June 1994
The three-loop QCD contributions to the vacuum polarization functions of the Z and W bosons at zero momentum are calculated. The top quark is considered to be massive and the other quarks massless.… Expand
Pole masses of quarks in dimensional reduction
- L. Avdeev, M. Kalmykov
- Physics
- 16 January 1997
Abstract Pole masses of quarks in quantum chromodynamics are calculated to two-loop order in the framework of the regularization by dimensional reduction. For the diagram with a light quark loop, the… Expand
Dimensional Regularization and Supersymmetry
- L. Avdeev, A. Vladimirov
- Physics
- 13 June 1983
Abstract We examine in detail the techniques of supersymmetric dimensional regularization. A peculiar complementarity is found to be inherent in the regularization: its manifestly supersymmetric… Expand
Renormalizations in softly broken SUSY gauge theories
- L. Avdeev, D. Kazakov, I. Kondrashuk
- Physics, Engineering
- 18 September 1997
The supergraph technique for calculations in supersymmetric gauge theories where supersymmetry is broken in a "soft" way (without introducing quadratic divergencies) is reviewed. By introducing an… Expand
Antisymmetric tensor matter fields. An abelian model
- L. Avdeev, M. Chizhov
- Physics
- 27 January 1994
Abstract We present a simple renormalizable abelian gauge model which includes antisymmetric second-rank tensor fields as matter fields rather than gauge fields known for a long time. The free action… Expand
Solutions of the Bethe ansatz equations for XXX antiferromagnet of arbitrary spin in the case of a finite number of sites
The exactly integrable isotropic Heisenberg chain of N spins s is studied, and numerical solutions to the Bethe ansatz equations corresponding to the antiferromagnetic vacuum (for sN less than or… Expand
