Renormalization of Chiral Perturbation Theory to Order p 6 *
نویسنده
چکیده
The renormalization of chiral perturbation theory is carried out to next-tonext-to-leading order in the meson sector. We calculate the divergent part of the generating functional of Green functions of quark currents to O(p6) for chiral SU(n), involving oneand two-loop diagrams. The renormalization group equations for the renormalized low-energy constants of O(p6) are derived. We compare our results with previous two-loop calculations in chiral perturbation theory. * Work supported in part by TMR, EC-Contract No. ERBFMRX-CT980169 (EURODAΦNE).

The divergences of the generating functional of quenched Chiral Perturbation theory (qCHPT) to one loop are computed in closed form. We show how the quenched chiral logarithms can be reabsorbed in the renormalization of the B0 parameter of the leading order Lagrangian. Finally, we do the chiral power counting for the quenched case and show that also finite loop corrections may diverge in the ch...
متن کاملField Redefinitions and Wave Function Renormalization to O ( p 4 ) in Heavy Baryon Chiral Perturbation Theory
Massand wave function renormalization is calculated to order p4 in heavy baryon chiral perturbation theory. Two different schemes used in the literature are considered. Several technical issues like field redefinitions, non-transformation of sources as well as subtleties related to the definition of the baryon propagator are discussed. The nucleon axial-vector coupling constant gA is calculated...
متن کاملThe anomalous chiral Lagrangian of order p 6
We construct the effective chiral Lagrangian for chiral perturbation theory in the mesonic odd-intrinsic-parity sector at order p6. The Lagrangian contains 24 in principle measurable terms and no contact terms for the general case of Nf light flavours, 23 terms for three and 5 for two flavours. In the two flavour case we need a total of 13 terms if an external singlet vector field is included. ...

A proper estimation of the chiral low-energy constants of Chiral Perturbation Theory is a very important task. To this end resonance chiral Lagrangians have been used fruitfully. We have studied the determination of chiral couplings at next-to-leading (NLO) order in the 1/N C expansion, keeping full control of the renormalization scale dependence. We find that, by imposing short-distance constr...
متن کاملWeak hyperon decays in heavy baryon chiral perturbation theory: Renormalization and applications
The complete renormalization of the weak Lagrangian to chiral order q2 in heavy baryon chiral perturbation theory is performed using heat kernel techniques. The results are compared with divergences appearing in the calculation of Feynman graphs for the nonleptonic hyperon decay Λ → pπ− and an estimate for the size of the counterterm contributions to the s-wave amplitudes in nonleptonic hyperon...
