BRST Cohomology and Vacuum Structure of Two-Dimensional Chromodynamics
Using a formulation of QCD2 as a perturbed conformally invariant theory involving fermions, ghosts, as well as positive and negative level Wess-Zumino-Witten fields, we show that the BRST conditions become restrictions on the conformally invariant sector, as described by a G/G topological theory. By solving the corresponding cohomology problem we are led to a finite set of vacua. For G = SU(2) ...
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 کاملDe Rham Cohomology of the Supermanifolds and Superstring BRST Cohomology
We show that the BRST operator of Neveu-Schwarz-Ramond superstring is closely related to de Rham differential on the moduli space of decorated super-Riemann surfaces P. We develop formalism where superstring amplitudes are computed via integration of some differential forms over a section of P over the super moduli space M. We show that the result of integration does not depend on the choice of...
متن کاملBrst Cohomology in Beltrami Parametrization
We study the BRST cohomology within a local conformal Lagrangian eld theory model built on a two dimensional Riemann surface with no boundary. We deal with the case of the complex structure parametrized by Beltrami di erential and the scalar matter elds. The computation of all elements of the BRST cohomology is given.
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.
