El objetivo principal de la presente tesis es implementar resultados de las extensiones unitarias de la teor\u00eda de perturbaciones quiral en procesos espec\u00edficos de desintegraci\u00f3n y producci\u00f3n de resonancias hadr\u00f3nicas. La gran riqueza y virtud de la teor\u00eda es que muchas resonancias (particularmente los mesones escalares) se generan din\u00e1micamente partiendo \u00fanicamente de los lagrangianos de menor orden de la teor\u00eda quiral de perturbaciones e implementado unitariedad en canales acoplados y explotando las propiedades de analiticidad de las amplitudes de dispersi\u00f3n. Es decir, muchas resonancias surgen din\u00e1micamente sin la necesidad de introducirlas como grados explicitos de libertad. Las reacciones que hemos estudiado han sido eta– mayor que pi0pi0gamma, phi– mayor que ppgamma y j\/psi- mayor que vpp. Con la inclusion de los mecnaismos relevantes e implentando la interacci\u00f3n de estado final de los mesones pseudosclaraes mediante las t\u00e9cnicas quirales unitarias hemos obtenido una buena descripci\u00f3n de los procesos considerados explicando el importante papel que juegan los mesones escalares en su din\u00e1mica interna. por otro lado, usando las tecnicas quirales unitarias hemos obtenido que los mesones axial-vector de menor masa tienen una gran componente de origen din\u00e1mico mediante la interacci\u00f3n del octete de vectores pseudoscalres con el de los vectores. En la segunda parte de la tesis hemos estudiado la viabilidad de observar la modificaci\u00f3n de las propiedades en materia nuclear de citas resonancias (sigma, rho y phi) usando reacciones especificas de producci\u00f3n en n\u00facleos. Usando fotoproducci\u00f3n de dos piones en nucleos vimos que en esta reacci\u00f3n se observa un corriemiento de la intensiad en la mas invariante d elos dos piones hacia bajas massa invariantes debido a la disminuci\u00f3n de la masa del meson sigam. En el caso del rho observamos un efecto peque\u00f1o debido a que la fuerte absorcion de los piones hace que la reaccion sea m<\/p>\n
