Next, we estimate some physical parameters associated to this interaction. These parameters include scattering length and the Ξ axial coupling constant (𝑔A). Finally, we compare our results to One Boson Exchange models5 p.application/pdfengcc-by-nc-nd (c) Ayyash, 2019http://creativecommons.org/licenses/by-nc-nd/3.0/es/Cromodinàmica quànticaBarionsHadronsTreballs de fi de grauQuantum chromodynamicsBaryonsHadronsBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
