Goldberger-Treiman relation and Wu-type experiment in the decuplet sector
Magnus Bertilsson, Stefan Leupold
The leading-order chiral Lagrangian for the baryon octet and decuplet states coupled to Goldstone bosons and external sources contains six low-energy constants. Five of them are fa…

Light quark mass dependence of nucleon electromagnetic form factors in dispersively modified chiral perturbation theory
Fernando Alvarado, Di An, Luis Alvarez-Ruso +1
The nucleon isovector electromagnetic form factors are calculated up to next-to-next-to-leading order by combining relativistic chiral perturbation theory (ChPT) of pion, nucleon,…
