Joint chiral and conformal bosonization in QCD and the linear sigma model

Chiral bosonization ofU A (1)-currents and the energy-momentum tensor in quantum chromodynamics

“…where :D =~ + e-a(S + iP75 ) --~9 + S + ifi75 with q --e-2~r Thus, the conformal metric is induced by local dilatations of the Dirac operator q --+ e-~/2q, and the corresponding effective action is calculated by integration over the conformal anomaly [6].…”

“…In Sec. 4, we use the conformal anomaly of the quark determinant [6] to construct the chiral Lagrangian in the external conformal-flat metric of the space-time. It would suffice to determine three structural constants of the generalized chiral Lagrangian at the vertices which characterize the meson matrix elements of the energymomentum tensor.…”

Exotic baryons and monopole excitations in a chiral soliton model

“…The coupling of the scalar field in L SB is such as to reproduce the explicit breaking in the dilation anomaly equation [28]. The various parameters in eqs.…”

Inquiry for the π+-π− bound state conversion into two π0's as being due to the Weinberg π-π interaction

“…If the consistent τ calculation in framework of a certain method of ππ-interaction description (see, for instance Refs. [4,5,12]) is carried out and, subsequently, its result is confronted to the experimental τ value, the validity of this method will come to light. We are on the point of inquiring into the various ππ-interaction representations in the course of pionium lifetime studying.…”
