Resumen
TRABAJANDO EN EL CONTEXTO DEL MODELO NO RELATIVISTA DE QUARKS, SE PRESENTA UN AJUSTE DE DOS PARÁMETROS A LOS MOMENTOS MAGNÉTICOS DE LOS BARIONES. EL AJUSTE TIENE UN ?2 EXCELENTE. EL MODELO ESTÁ BASADO EN TOMAR DIFERENTES GRUPOS DE SABOR PARA DESCRIBIR DIFERENTES MOMENTOS MAGNÉTICOS. LA ASIGNACIÓN DE GRUPOS A BARIONES SE BASA EN LA ESTRUCTURA DE SU FUNCIÓN DE ONDA. EL MODELO CORRESPONDE A ASIGNAR DIFERENTES MASAS EFECTIVAS A LOS QUARKS DEPENDIENDO DE QUE BARIÓN SE TRATE. USANDO LOS VALORES PROPORCIONADOS POR EL AJUSTE, LOS MOMENTOS MAGNÉTICOS DE LA ?- Y LA ?++ HAS SIDO CALCULADOS Y LA COMPARACIÓN CON VALORES EXPERIMENTALES EXISTENTES ES MUY SATISFACTORIA.AbstractWORKING WITHIN THE NON RELATIVISTIC QUARK MODEL, A TWO PARAMETER FIT TO THE MAGNETIC MOMENTS OF BARYONS IS PRESENTED. THE FIT HAS AN EXCELLENT 2. THE MODEL IS BASED ON TAKING DIFFERENT FLAVOR GROUPS TO DESCRIBE THE DIFFERENT MAGNETIC MOMENTS. THE SELECTION OF WHICH GROUP TO ASSIGN TO EACH BARYON IS GUIDED BY THE STRUCTURE OF ITS WAVEFUNCTION. THE MODEL CORRESPONDS TO ASSIGNING DIFFERENT EFFECTIVE MASSES TO A QUARK DEPENDING ON WHICH BARYON IS BEING CONSIDERED. USING THE VALUES EXTRACTED FROM THE FIT, THE MAGNETIC MOMENTS OF THE AND THE HAVE BEEN PREDICTED, AND THE COMPARISON TO THE EXISTING EXPERIMENTAL VALUES IS QUITE SATISFACTORY.
