Hexagons and correlators in the fishnet theory
(2019-11-01)
We investigate the hexagon formalism in the planar 4d conformal fishnet theory. This theory arises from N = 4 SYM by a deformation that preserves both conformal symmetry and integrability. Based on this relation, we obtain ...
Optimized δ expansion for the Walecka model
(Elsevier B.V., 1996-03-07)
The optimized δ-expansion is used to study vacuum polarization effects in the Walecka model. The optimized δ-expansion is a nonperturbative approach for field theoretic models which combines the techniques of perturbation ...
Higher grading conformal affine Toda theory and (generalized) sine-Gordon/massive Thirring duality
(2003-11-01)
Some properties of the higher grading integrable generalizations of the conformal affine Toda systems are studied. The fields associated to the non-zero grade generators are Dirac spinors. The effective action is written ...
