On the other hand, the large-N-c limit helps to impose natural short-distance constraints on these low-energy constants, providing a parameter reduction. A Bayesian interpretation of the expected 1/N-c accuracy allows for an easy and efficient implementation of these constraints, using an augmented chi(2). We apply this approach to the analysis of meson-meson scattering, in conjunction with chiral perturbation theory to one loop and coupled-channel unitarity, and show that it helps to largely reduce the many existing ambiguities and simultaneously provide an acceptable description of the available phase shifts.", optnote="WOS:000348730800008", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=2100), last updated on Thu, 26 Feb 2015 17:05:02 +0000", issn="1550-7998", doi="10.1103/PhysRevD.90.114020", opturl="http://arxiv.org/abs/1407.3750", opturl="https://doi.org/10.1103/PhysRevD.90.114020", archivePrefix="arXiv", eprint="1407.3750", language="English" }
