Matching Pion-Nucleon Roy-Steiner Equations to Chiral Perturbation Theory.
We match the results for the subthreshold parameters of pion-nucleon scattering obtained from a solution of Roy-Steiner equations to chiral perturbation theory up to next-to-next-to-next-to-leading order, to extract the pertinent low-energy constants including a comprehensive analysis of systematic uncertainties and correlations. We study the convergence of the chiral series by investigating th...
متن کاملMatching Current Correlators in Lattice QCD to Chiral Perturbation Theory
Chiral perturbation theory gives direct and unambiguous predictions for the form of various two-point hadronic correlators at low momentum in terms of a finite set of couplings in a chiral Lagrangian. In this paper we study the feasibility of extracting the couplings in the chiral Lagrangian (through 1-loop order) by fitting two-point correlators computed in lattice QCD to the predicted chiral ...

BES II data for J/Ψ → K * (890)Kπ reveal a strong κ peak in the Kπ S-wave near threshold. Both magnitude and phase are determined in slices of Kπ mass by interferences with strong K 0 (1430), K 1 (1270) and K 1 (1400) signals. The phase variation with mass agrees within errors with LASS data for Kπ elastic scattering. A combined fit is presented to both BES and LASS data. The fit uses a Breit-W...
متن کاملChiral Perturbation Theory and Unitarization
We review our recent work on unitarization and chiral perturbation theory both in the ππ and the πN sectors. We pay particular attention to the Bethe-Salpeter and Inverse Amplitude unitarization methods and their recent applications to ππ and πN scattering.

Abstract. The charged kaon decay channel K l3γ allows for studies of direct CP violation, possibly due to non-standard mechanisms, with the help of T -odd correlation variables. In order to be able to extract a CP -violating signal from experiment, it is necessary to understand all possible Standard Model phases that also produce T -odd asymmetries. We complement earlier studies by considering ...
