Effective chiral theory of mesons, coefficients of ChPT, axial-vector symmetry breaking
نویسنده
چکیده
A phenomenological successful effective chiral theory of pseudoscalar, vector, and axial-vector mesons is introduced. Based on this theory all the 10 coefficients of ChPT are predicted. It has been found that a new symmetry breaking-axial-vector symmetry breaking is responsible for the mass difference between ρ and a1 mesons. It is shown that in an EW theory without Higgs mW and mZ are dynamicallu generated by the combination of the fermion masses and the axial-vector symmetry breaking: mW = 1 √ 2 gmt, mZ = ρmW /cosθW with ρ ≈ 1, and GF = 1/(2 √ 2m2t ). Two gauge fixing terms of W and Z fields are dynamically generated too.

Se p 19 99 The Extended Chiral Quark Model confronts QCD
We discuss the truncation of low energy effective action of QCD below the chiral symmetry breaking (CSB) scale, including all operators of dimensionality less or equal to 6 which can be built with quark and chiral fields. We perform its bosonization in the scalar, pseudoscalar, vector and axial-vector channels in the large-N c and leading-log approximation. Constraints on the coefficients of th...
متن کاملO ct 2 00 1 EFFECTIVE CHIRAL THEORY OF LARGE N C QCD OF MESONS
An effective chiral theory of pseudoscalars, vectors, and axial-vectors is presented. In this theory mesons are coupled to quarks. At quark level mesons have no kinetic terms which are generated by quark loops. The theory has both explicit chiral sym-metry(in the limit, m q → 0) and dynamical chiral symmetry breaking. Large N C expansion is a natural result. Tree diagrams are at leading order a...
متن کاملChiral Quark Model of Mesons
We study SU(3)L×SU(3)R chiral quark model of mesons up to next leading order of 1/Nc expansion. Composite vector and axial-vector mesons resonances are introduced via non-linear realization of chiral SU(3) and vector meson dominant. Effects of one-loop graphs of pseudoscalar, vector and axial-vector mesons is calculated systematically and the significant results are obtained. Correction of effe...

We extend an effective Lagrangian embodying broken scale and chiral symmetry to include explicit chiral symmetry breaking and an additional chiral invariant term which allows for an axial coupling constant greater than unity. We also include a chiral Lagrangian for the isotriplet vector mesons which leads to a renormalization of the pion field. The properties of nuclear matter and nuclei, low e...
