1. Proton charge radius extraction from electron scattering data using dispersively improved chiral effective field theory / Alarcón, J.M. ; Higinbotham, D.W. ; Weiss, C. ; Ye, Zhihong
We extract the proton charge radius from the elastic form factor (FF) data using a novel theoretical framework combining chiral effective field theory and dispersion analysis. [...]

5. Chiral perturbation theory of muonic-hydrogen Lamb shift: polarizability contribution / Alarcón, Jose Manuel ; Lensky, Vadim ; Pascalutsa, Vladimir
The proton polarizability effect in the muonic-hydrogen Lamb shift comes out as a prediction of baryon chiral perturbation theory at leading order and our calculation yields ΔE(pol)(2P-2S)=8-1+3μ eV. [...]

6. The strangeness content of the nucleon from effective field theory and phenomenology / Alarcón, J.M. ; Geng, L.S. ; Martin Camalich, J. ; Oller, J.A.
We revisit the classical relation between the strangeness content of the nucleon, the pion–nucleon sigma term and the SU(3)F breaking of the baryon masses in the context of Lorentz covariant chiral perturbation theory with explicit decuplet-baryon resonance fields. [...]
