Effective chiral Lagrangian from dual resonance models.
Parameters of the effective chiral lagrangian (EChL) of orders O(p) and O(p6) are extracted from low–energy behaviour of dual resonance models for ππ and πK scattering amplitudes. Dual resonance models are considered to be good candidates for the resonance spectrum and for hadronic scattering amplitudes in the large Nc limit of QCD. We discuss dual resonance models in the presence of spontaneou...
متن کاملA Supersymmetric Effective Chiral Lagrangian
We construct in a manifestly supersymmetric form the leading and subleading terms in momentum for an effective supersymmetric chiral Lagrangian in terms of complex pions and their superpartners. A soft supersymmetry breaking term is included and below the super-symmetry breaking scale the Lagrangian reduces to the usual bosonic chiral Lagrangian in terms of real pions.
متن کاملReinterpretation of Effective Chiral Lagrangian
Effective Tree Chiral Lagrangian is interpreted as a power series expansion of the kinematical variables. In the presence of the strong interaction this expansion is valid below the unitarity cut, hence in the unphysical region. Consequences of this reinterpretation of the Chiral Lagrangian are analysed for the relation between K − π and K − 2π transitions. ∗unité propre 014 du CNRS
متن کاملEffective electroweak chiral Lagrangian: The matter sector
We parametrize in a model-independent way possible departures from the minimal standard model predictions in the matter sector. We only assume the symmetry breaking pattern of the standard model and that new particles are sufficiently heavy so that the symmetry is nonlinearly realized. Models with dynamical symmetry breaking are generically of this type. We review in effective theory language t...
متن کاملEffective chiral lagrangian in the chiral limit from the instanton vacuum
Department of Physics, Pusan National University, 609-735 Busan, Republic of Korea (Dated: August 2003) Abstract We study the effective chiral Lagrangian in the chiral limit from the instanton vacuum. Starting from the nonlocal effective chiral action, we derive the effective chiral Lagrangian, using the derivative expansion to order O(p4) in the chiral limit. The low energy constants, L1, L2, ...
