Final state interactions and Khuri-Treiman equations in,ν → 3π decays
Using extended Khuri-Treiman equations, we evaluate the final state interactions due to two-pion rescatterings to the decays ν → π0π+π− and ν → π0π0π0. As subtraction to the dispersion relation weExpand

Chiral structure of the nucleon
Abstract We analyze the structure of QCD Green functions with one external nucleon, treated as a very massive field. We discuss the matching conditions and relations of various nucleon matrixExpand

The Δ(1232) as an effective degree of freedom in chiral perturbation theory
Heavy baryon chiral perturbation theory including spin 3/2 delta resonances as effective degrees of freedom is reviewed. The theory admits a systematic expansion in the small scale e, where eExpand

Two-loop analysis of vector-current propagators in chiral perturbation theory
We perform a calculation of the isospin and hypercharge vector-current propagators (ΔV33μν(q2) and ΔV88μν(q2)) to two loops in chiral perturbation theory. The analysis is carried out withExpand

K-->2π and K-->3π decays in next-to-leading order chiral perturbation theory
Abstract We evaluate the next-to-leading corrections to K→2π and K→3π decays in chiral perturbation theory. Fitting the counterterm coupling constants of the next-to-leading order corrections toExpand

The chiral loop expansion of the nonleptonic weak interactions of mesons
Abstract In the framework of the effective low-energy chiral lagrangian, we determine the one-loop effective action describing the strangeness-changing nonleptonic weak interactions of theExpand

Decay constants, light quark masses, and quark mass bounds from light quark pseudoscalar sum rules
The flavor $ud$ and $us$ pseudoscalar correlators are investigated using families of finite energy sum rules (FESR's) known to be very accurately satisfied in the isovector vector channel. It isExpand

mu+md from isovector pseudoscalar sum rules
Abstract We revisit the isovector pseudoscalar sum rule determination of mu+md, using families of finite energy sum rules known to be very accurately satisfied in the isovector vector channel. TheExpand

Delta(1232) and the polarizabilities of the nucleon
Previous calculations of the polarizabilities of the nucleon within the framework of heavy baryon chiral perturbation theory have included the contribution of the {Delta}(1232) only in its effects onExpand
