Properties of Nucleon Resonances by means of a Genetic Algorithm
C. Fernandez-Ramirez, E. Moya de Guerra, A. Udias +1
We present an optimization scheme that employs a Genetic Algorithm (GA) to determine the properties of low-lying nucleon excitations within a realistic photo-pion production model…
Final-State Interactions in the Superscaling Analysis of Neutral-Current Quasielastic Neutrino Scattering
M. C. Martinez, J. A. Caballero, T. W. Donnelly +1
Effects of strong final-state interactions in the superscaling properties of neutral-current quasielastic neutrino cross sections are investigated using the Relativistic Impulse Ap…
Spin asymmetry for the 16O(gamma,pi- p) reaction in the Delta(1232) region within an effective Lagrangian approach
C. Fernandez-Ramirez, M. C. Martinez, J. R. Vignote +1
The spin asymmetry of the photon in the exclusive A(gamma,pi N)A-1 reaction is computed employing a recently developed fully relativistic model based on elementary pion production…
Superscaling Predictions for Neutral Current Quasielastic Neutrino-Nucleus Scattering
M. C. Martinez, J. A. Caballero, T. W. Donnelly +1
The application of superscaling ideas to predict neutral-current (NC) quasielastic (QE) neutrino cross sections is investigated. Results obtained within the relativistic impulse ap…
Crossing symmetry and phenomenological widths in effective Lagrangian models of the pion photoproduction process
C. Fernandez-Ramirez, E. Moya de Guerra, J. M. Udias
We investigate the importance of crossing symmetry in effective field models and the effects of phenomenological nucleon resonance widths on the paradigmatic case of pion photoprod…
Eta Photoproduction as a Test of the Extended Chiral Symmetry
C. Fernandez-Ramirez, E. Moya de Guerra, J. M. Udias
We analyze the process from threshold up to 1.2 GeV, employing an effective Lagrangian approach that allows for a mixing of eta couplings of pseudoscalar and pseudovect…
