Transverse charge and current densities in the nucleon from dispersively improved chiral effective field theory
J. M. Alarcón, C. Weiss
Background: The transverse densities describe the distributions of electric charge and magnetic moment at fixed light-front time and connect the nucleon's elastic for…
Forward doubly-virtual Compton scattering off the nucleon in chiral perturbation theory: II. Spin polarizabilities and moments of polarized structure functions
Jose Manuel Alarcón, Franziska Hagelstein, Vadim Lensky +1
We examine the polarized doubly-virtual Compton scattering (VVCS) off the nucleon using chiral perturbation theory (PT). The polarized VVCS contains a wealth of information on t…
Forward doubly-virtual Compton scattering off the nucleon in chiral perturbation theory: the subtraction function and moments of unpolarized structure functions
Jose Manuel Alarcón, Franziska Hagelstein, Vadim Lensky +1
The forward doubly-virtual Compton scattering (VVCS) off the nucleon contains a wealth of information on nucleon structure, relevant to the calculation of the two-photon-exchange e…

J. M. Alarcón, D. W. Higinbotham, C. Weiss
We extract the proton magnetic radius from the high-precision electron-proton elastic scattering cross section data. Our theoretical framework combines dispersion analysis and chir…
Nucleon form factors in dispersively improved Chiral Effective Field Theory II: Electromagnetic form factors
J. M. Alarcón, C. Weiss
We study the nucleon electromagnetic form factors (EM FFs) using a recently developed method combining Chiral Effective Field Theory (EFT) and dispersion analysis. The spectral…

J. M. Alarcón, A. N. Hiller Blin, M. J. Vicente Vacas +1
The baryon electromagnetic form factors are expressed in terms of two-dimensional densities describing the distribution of charge and magnetization in transverse space at fixed lig…
Gold-plated moments of nucleon structure functions in baryon chiral perturbation theory
Vadim Lensky, Jose Manuel Alarcón, Vladimir Pascalutsa
We obtain leading- and next-to-leading order predictions of chiral perturbation theory for several prominent moments of nucleon structure functions. These free-parameter free resul…
Low energy analysis of scattering and the pion-nucleon sigma term with covariant baryon chiral perturbation theory

The pion-nucleon sigma term () is an observable of fundamental importance because embodies information about the internal scalar structure of the nucleon. Nowadays this qua…

J. M. Alarcón, J. Martin Camalich, J. A. Oller
We present a novel analysis of the scattering amplitude in covariant baryon chiral perturbation theory up to within the extended-on-mass-shell renormalization…
