Non perturbative chiral approach to s-wave K̄N interactions
The s-wave meson-nucleon interaction in the S = −1 sector is studied by means of coupled-channel Lippmann Schwinger equations, using the lowest order chiral Lagrangian and a cut off to regularize the loop integrals. The method reproduces succesfully the Λ(1405) resonance and the K−p → K−p, K̄0n, π0Λ, π0Σ, π+Σ−, π−Σ+ cross sections at low energies. The inclusion of the ηΛ, ηΣ0 channels in the cou...
متن کاملNon-perturbative Approach to effective chiral Lagrangians and Meson Interactions
We develop a coupled channel unitary approach describing the behavior at higher energies of systems whose low-energy dynamics is given by effective O(p) and O(p) chiral Lagrangians. Our free parameters are those of the O(p) Lagrangian. When applied to the meson-meson interaction, it yields a remarkable agreement with data up to √ s ' 1.2 GeV, dynamically generating the σ, f0, a0, ρ and K ∗ reso...
متن کاملnon-corrective approach to pronunciation
the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
15 صفحه اولNon - perturbative chiral approach to K − p → γY reactions
A recently developed nonperturbative chiral approach to describe the S = −1 meson-baryon reactions has been extended to investigate the near threshold K − p → γΛ, γΣ 0 reactions. With the parameters governed by chiral SU(3) symmetry, we show that the predicted branching ratios Γ K − p→γΛ /Γ K − p→all and Γ K − p→γΣ 0 /Γ K − p→all are close to the experimental values. The coupling with the η cha...
متن کاملMeson-Meson interaction in a non-perturbative chiral approach
A non-perturbative method which combines constraints from chiral symmetry breaking and coupled channel unitarity is used to describe the meson-meson interaction up to about 1.2 GeV. The approach uses the O(p2) and O(p4) chiral Lagrangians. The seven free parameters of the O(p4) Lagrangian are fitted to the data. The results are in good agreement with a vast amount of experimental analyses. The ...
