Effective Weak Chiral Lagrangian to O(p4) in the Chiral Quark Model
We investigate the ∆S = 1 effective weak chiral Lagrangian within the framework of the chiral quark model. Starting from the effective four-quark operators, we derive the effective weak chiral action by integrating out the constituent quark fields. Employing the derivative expansion, we obtain the effective weak chiral Lagrangian to order O(p4). We examine the contributions of the order O(Nc) t...
متن کاملThe chiral effective pion – nucleon Lagrangian of order p
We construct the minimal effective chiral pion–nucleon SU(2) Lagrangian at fourth order in the chiral expansion. The Lagrangian contains 118 in principle measurable terms. We develop both the relativistic as well as the heavy baryon formulation of the effective field theory. For the latter, we also work out explicitly all 1/m corrections at fourth order. We display all relevant relations needed...
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 کاملElectromagnetic couplings of the chiral perturbation theory Lagrangian from the perturbative chiral quark model
We apply the perturbative chiral quark model to the study of the low-energy πN interaction. Using an effective chiral Lagrangian we reproduce the Weinberg-Tomozawa result for the S-wave πN scattering lengths. After inclusion of the photon field we give predictions for the electromagnetic O(p2) lowenergy couplings of the chiral perturbation theory effective Lagrangian that define the electromagn...
