Extraction of the nucleon axial form factor from Lattice QCD using NNLO chiral perturbation theory

Fernando Alvarado, Luis Alvarez-Ruso

We calculate the nucleon axial form factor in relativistic chiral perturbation theory with up to next-to-next-to-leading order (NNLO). Relevant low-energy constants are d…

Hyperon non-leptonic decays in relativistic Chiral Perturbation Theory with resonances

Nora Salone, Fernando Alvarado, Stefan Leupold +1

Motivated by recent experimental advances in the corresponding measurements, non-leptonic hyperon decays are calculated, for the first time in a relativistic manner, in Chiral Pert…

The weak decay including new physics

Fernando Alvarado, Luis Alvarez-Ruso, Eliecer Hernandez +2

We investigate the decay with a focus on potential new physics (NP) effects in the channel. We employ an effective Hamiltonian within the fram…

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,…

Light-quark mass dependence of the nucleon axial charge and pion-nucleon scattering phenomenology

Fernando Alvarado, Luis Alvarez-Ruso

The light-quark mass dependence of the nucleon axial isovector charge () has been studied up to next-to-next-to-leading order, , in relativistic chiral perturbation th…

Simple explanation of strong suppression of fermionic EFT operators and custodial symmetry breaking

Adolfo Guevara, Fernando Alvarado, Juan José Sanz Cillero

The present approach relies on the SM chiral symmetry breaking pattern , with the EW Goldstone bosons given in a non-linear realization and t…
