RESUMEN: En un modelo con grupo de norma GSM ⊗ U(1)X, donde GSM ≡ SU(3)C ⊗ SU(2)L ⊗ U(1)Y es el grupo de norma del modelo est´andar y U(1)X es el grupo de una simetr´ıa horizontal local, se propone la generaci´on radiativa del espectro de masas y los ´angulos de mezcla de los quarks. La asignaci´on de las cargas horizontales es tal que a nivel ´arbol solamente la tercera familia es masiva. Usando las masas a nivel ´arbol e introduciendo escalares ex´oticos, los quarks de las familias ligeras adquieren masas jer´arquicas a trav´es de correcciones radiativas. Las matrices de rango tres que se obtiene se expresan en t´erminos de un conjunto m´ınimo de par´ametros del modelo, cuyos valores se estiman realizando un ajuste num´erico. Las masas de los quarks y los ´angulos de mezcla obtenidos est´an en acuerdo con los valores experimentales. |

The assignment of horizontal charges is such that at tree level only the third family is massive. Using these tree level masses and introducing exotic scalars, the light families ofquarks acquire hierarchical masses through radiative corrections. The rank three quark mass matrices obtained are written in terms of a minimal set of free parameters of the model, whose values are estimated performing a numerical fit. The resulting quark masses and CKM mixing angles turn out to be in good agreement with the experimental values.6application/pdfengSociedad Mexicana de FísicaMéxicohttps://creativecommons.org/licenses/by-nc/4.0/https://creativecommons.org/licenses/by-nc/2.5/co/Atribución-NoComercial 2.5 Colombia (CC BY-NC 2.5 CO)info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2CKMHorizontal symmetryQuark massesMasas de los quarksSimetria horizontalHierarchical radiative quark mass matrices with an U(1)x horizontal symmetry modelMatrices de masa de quark radiativas jerárquicas con un modelo de simetría U(1)x horizontalArtículo de investigaciónhttp://purl.org/coar/resource_type/c_2df8fbb1https://purl.org/redcol/resource_type/ARThttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion3813248Revista Mexicana de FísicaPublicationCC-LICENSElicense_urllicense_urltext/plain;
