Wilson-’t Hooft operators and the theta angle
We consider (3+1)-dimensional SU(N)/ZN Yang-Mills theory on a space-time with a compact spatial direction, and prove the following result: Under a continuous increase of the theta angle θ → θ+2π, a ’t Hooft operator T (γ) associated with a closed spatial curve γ that winds around the compact direction undergoes a monodromy T (γ) → T (γ). The new ’t Hooft operator T (γ) transforms under large ga...
متن کاملNoncommutative ’t Hooft Instantons
We employ the twistor approach to the construction of U(2) multi-instantons à la ’t Hooft on noncommutative R. The noncommutative deformation of the Corrigan-Fairlie-’t Hooft-Wilczek ansatz is derived. However, naively substituting into it the ’t Hooft-type solution is unsatisfactory because the resulting gauge field fails to be self-dual on a finite-dimensional subspace of the Fock space. We r...
متن کاملInteraction Energy of ‘t Hooft-Polyakov Monopoles
The dependence of the energies of axially symmetric monopoles of magnetic charges 2 and 3, on the Higgs self-interaction coupling constant, is studied numerically. Comparing the energy per unit topological charge of the charge-2 monopole with the energy of the spherically symmetric charge-1 monopole, we confirm that there is only a repulsive phase in the interaction energy between like monopoles
متن کاملDerivative expansion of quadratic operators in a general ’t Hooft gauge
A derivative expansion technique is developed to compute functional determinants of quadratic operators, non diagonal in spacetime indices. This kind of operators arise in general ’t Hooft gauge fixed Lagrangians. Elaborate applications of the developed derivative expansion are presented. Typeset using REVTEX 1
متن کاملThe ’t Hooft vertex revisited
In 1976 ’t Hooft introduced an elegant approach towards understanding the physical consequences of the topological structures that appear in non-Abelian gauge theories. These effects are concisely summarized in terms of an effective multifermion interaction. These old arguments provide a link between a variety of recent and sometimes controversial ideas including discrete chiral symmetries appe...
