The Effective Lagrangian of Three Dimensional Quantum Chromodynamics
We consider the low energy limit of three dimensional Quantum Chromodynamics with an even number of flavors. We show that Parity is not spontaneously broken, but the global (flavor) symmetry is spontaneously broken. The low energy effective lagrangian is a nonlinear sigma model on the Grassmannian. Some Chern–Simons terms are necessary in the lagrangian to realize the discrete symmetries correc...
متن کاملThree Dimensional Quantum Chromodynamics †
The subject of this talk was the review of our study of three (2 + 1) dimensional Quantum Chromodynamics. In our previous works, we showed the existence of a phase where parity is unbroken and the flavor group U (2n) is broken to a subgroup U (n) × U (n). We derived the low energy effective action for the theory and showed that it has solitonic excitations with Fermi statistic, to be identified...
متن کاملBaryons as Solitons in Three Dimensional Quantum Chromodynamics
We show that baryons of three dimensional Quantum Chromodynamics can be understood as solitons of its effective lagrangian. In the parity preserving phase we study, these baryons are fermions for odd N c and bosons for even N c , never anyons. We quantize the collective variables of the solitons and there by calculate the flavor quantum numbers, magnetic moments and mass splittings of the baryo...
متن کاملMassive Two-Dimensional Quantum Chromodynamics
In this work we study the zero-charge sector of massive two-dimensional Quantum Chromodynamics in the decoupled formulation. We find that some general features of the massless theory, concerning the constraints and the rightand left-moving character of the corresponding BRST currents, survive in the massive case. The implications for the integrability properties previously valid in the massless...
متن کاملTwo Dimensional Quantum Chromodynamics on a Cylinder
We study two dimensional Quantum Chromodynamics with massive quarks on a cylinder in a light–cone formalism. We eliminate the non–dynamical degrees of freedom and express the theory in terms of the quark and Wilson loop variables. It is possible to perform this reduction without gauge fixing. The fermionic Fock space can be defined independent of the gauge field in this light–cone formalism.
