Order Parameter of the Chiral Symmetry Breaking Green Functions at One Loop *
نویسنده
چکیده
Since order parameter of the chiral symmetry breaking Green Functions are a useful link between the OPE expansion and χPT we perform a calculation to the NLO in αs, working in the chiral limit, for all the 2 and 3 point ones. These Green Functions have no perturbative term in the chiral limit and thence their main contribution comes from the ¯ qq operator.

OPE–RχT matching at order αs: hard gluonic corrections to three–point Green functions
In this work we push the matching between the QCD operator product expansion (OPE) and resonance chiral theory (RχT) to order αs. To this end we compute two– and three–point QCD Green functions (GFs) in both theories and compare the results. GFs which are order parameters of chiral symmetry breaking make this matching more transparent and thus we concentrate on those. On the OPE side one needs ...
متن کاملDeconfinement through Chiral Symmetry Restoration in Two-Flavour QCD
We propose that in QCD with dynamical quarks, colour deconfinement occurs when an external field induced by the chiral condensate strongly aligns the Polyakov loop. This effect sets in at the chiral symmetry restoration temperature Tχ and thus makes deconfinement and chiral symmetry restoration coincide. The predicted singular behaviour of Polyakov loop susceptibilities at Tχ is shown to be sup...
متن کاملChiral and U(1) axial symmetry restoration in linear sigma models with two quark flavors
We study the restoration of chiral symmetry in linear sigma models with two quark flavors. The models taken into consideration have a U(2) × U(2) and an O(N) internal symmetry. The physical mesons of these models are σ, pion, η and a0 where the latter two are not present in the O(N) model. Including two-loop contributions through sunset graphs we calculate the temperature behavior of the order ...
متن کاملDynamical symmetry breaking in the external gravitational and constant magnetic fields
We investigate the effects of the external gravitational and constant magnetic fields to the dynamical symmetry breaking. As simple models of the dynamical symmetry breaking we consider the Nambu-Jona-Lasinio (NJL) model and the supersymmetric Nambu-Jona-Lasinio (SUSY NJL) model non-minimally interacting with the external gravitational field and minimally interacting with constant magnetic fiel...
متن کاملDeconfinement and Chiral Restoration in Hot and Dense Matter
It is widely accepted that Quantum Chromodynamics (QCD) has phase transitions at high temperature, the nature of which depends on the quark mass, mq. In the limit of mq = 0, QCD has chiral symmetry, SUL(Nf)× SUR(Nf), in the case of Nf flavors, that spontaneously breaks into SUV(Nf) at low temperatures. The chiral condensate, 〈q̄q〉, serves as an order parameter for chiral restoration at high temp...
