Final state interactions and Khuri-Treiman equations in,ν → 3π decays

- J. Kambor, C. Wiesendanger, D. Wyler
- Physics
- 23 September 1995

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 we… Expand

Chiral structure of the nucleon

- V. Bernard, N. Kaiser, J. Kambor, U. Meißner
- Physics
- 5 February 1992

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 matrix… Expand

The Δ(1232) as an effective degree of freedom in chiral perturbation theory

- J. Kambor
- Physics
- 26 November 1997

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 e… Expand

Two-loop analysis of vector-current propagators in chiral perturbation theory

- E. Golowich, J. Kambor
- Physics
- 17 January 1995

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 with… Expand

K-->2π and K-->3π decays in next-to-leading order chiral perturbation theory

- J. Kambor, J. Missimer, D. Wyler
- Physics
- 6 June 1991

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 to… Expand

The chiral loop expansion of the nonleptonic weak interactions of mesons

- J. Kambor, J. Missimer, D. Wyler
- Physics
- 10 December 1990

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 the… Expand

Decay constants, light quark masses, and quark mass bounds from light quark pseudoscalar sum rules

- K. Maltman, J. Kambor
- Physics
- 28 August 2001

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 is… Expand

mu+md from isovector pseudoscalar sum rules

- K. Maltman, J. Kambor
- Physics
- 6 July 2001

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. The… Expand

Delta(1232) and the polarizabilities of the nucleon

- T. Hemmert, B. Holstein, J. Kambor
- Physics
- 16 December 1996

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 on… Expand
