Meson-Baryon Effective Chiral Lagrangians to O(q3)
نویسندگان
چکیده
We construct the complete and minimalO(q2) and O(q3) three-flavour Lorentz invariant chiral meson-baryon Lagrangians for the first time in the literature. We compare with previous three-flavour studies reducing the number of independent monomials and adding new ones that were missing.

Meson-Baryon Effective Chiral Lagrangians at O(q): Erratum
After our work [1] was published, Frink and Meißner [2] pointed out that the O(q3) three-flavour meson-baryon chiral Lagrangian presented there was not minimal. Here, we discuss their findings and revise ours accordingly. We find out eight monomials in the Lagrangian presented in [1] are not independent, but in addition, two monomials were wrongly discarded there which, as a result, makes the a...
متن کاملMeson-Baryon Effective Chiral Lagrangian at O(q) Revisited
After our work [1] was published, Frink and Meißner [2] pointed out that the O(q3) three-flavour meson-baryon chiral Lagrangian presented there was not minimal. Here, we critically review their paper and revise ours. Remarkably, we find that the effective meson-baryon chiral Lagrangian at O(q3) contains 76 monomials, i.e. eight less than in [1] and two less than in [2].

A qualitative account of the meson-meson and meson-baryon interactions using chiral Lagrangians and the inverse amplitude method in coupled channels is done. The method, imposing exact unitarity, proves to be a very useful tool to extend the information contained in the chiral Lagrangians at energies beyond the realm of applicability of chiral perturbation theory.

متن کاملChiral Unitary approach to meson-meson and meson-baryon interactions and nuclear applications
We report on recent nonperturbative techniques that combine the information of chiral Lagrangians (with and without resonances) with unitarity in coupled channels and other requirements of the S-matrix theory of the strong interactions. As a result, the region of applicability of such techniques is much larger than the one of Chiral Perturbation Theory allowing one to study also resonance physi...
