Determinación de la asimetrı́a del haz de fotones para la reacción de redispersión γd → K+ Σ− p a partir de datos experimentales en un rango de energı́as entre 1,1 y 2,3 GeV

Abstract

In order to understand the structure of the nucleon, different spectroscopy experiments are carried out that allows validating the existing phenomenological models by extracting different observables that provide more information on the said structure and its properties. Therefore, in this work, we worked with the experimental data of the JLab corresponding to the g13 period of the year 2007 with linearly polarized photons in a range of energies from 1.1 to 2.3 GeV. A study of the γd→K + Σ−p the reaction was then carried out, addressing the specific case where rescattering occurs, for this, the reaction was reconstructed in principle and subsequently, the observable polarization asymmetry of the photon beam was determined. It was found in this research that there is a difference between the quasi-free case and the redispersion case for the values of the photon beam asymmetry.
