As at the considered order the extraction of. 0 is a pure prediction of chiral perturbation theory, the obtained values are a good test for this theory. After including explicitly the decuplet states, our SU(2) results have a very good agreement with the experimental data and we extend our framework to SU(3) to give predictions for the hyperons{\textquoteright}. 0 values. Prominent are the Sigma(-) and Xi(-) baryons as their photon transition to the decuplet is forbidden in SU(3) symmetry and therefore they are not sensitive to the explicit inclusion of the decuplet in the theory.", optnote="WOS:000364020300009", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=2451), last updated on Thu, 29 Sep 2016 10:48:22 +0000", issn="1550-7998", doi="10.1103/PhysRevD.92.096004", opturl="http://arxiv.org/abs/1509.00955", opturl="https://doi.org/10.1103/PhysRevD.92.096004", archivePrefix="arXiv", eprint="1509.00955", language="English" }
