Quark-Antiquark Bound States in an Extended QCD_2 Model
Pedro Labrana, Jorge Alfaro, Alexander A. Andrianov
We study an extended QCD model in 2D obtained from QCD in 4D by compactifying two spatial dimensions and projecting onto the zero-mode subspace. This system is found to induce a dy…
Berezin integration on noncompact supermanifolds
J. Alfaro, L. F. Urrutia
An heuristic derivation of the tranformation law for the Berezin integration measure in noncompact supermanifolds, obtained by Roshstein \cite{Ro}, is presented.
Bv Gauge Theories
Jorge Alfaro
Using the Non-Abelian Batalin-Vilkovisky formalism introduced recently, we present a generalization of the Yang-Mills gauge transformations , to include antisymmetric tensor fields…
Generalized Hirota Equations in Models of 2D Quantum Gravity
Jorge Alfaro, Ivan Kostov
We derive a set of bilinear functional equations of Hirota type for the partition functions of the related integrable statistical models defined on a random lattice. These…
Symmetries and the Antibracket
J. Alfaro, P. H. Damgaard
Requiring that a Lagrangian path integral leads to certain identities (Ward identities in a broad sense) can be formulated in a general BRST language, if necessary by the use of co…
Loop Equations for the d-dimensional n-Hermitian matrix model
J. Alfaro
We derive the loop equations for the d-dimensional n-Hermitian matrix model. These are a consequence of the Schwinger-Dyson equations of the model. Moreover we show that in leading…
