Tesis doctoral de Paula Herrera Siklody <\/strong><\/h2>\n

En el l\u00edmite de nc grande, la teor\u00eda de perturbaciones quirales puede extenderse al caso del nonete. La teor\u00eda resultante describe las interacciones de baja energ\u00eda entre los nueve bosones de goldstone (piones, kaones, y )que se generan a trav\u00e9s de larotura espont\u00e1nea de la simetria de sabor ul(3) ur(3) – uvz(3). en este trabajo, se construye el lagrangiano hasta orden o(p4). Se da tambi\u00e9n la renormalizaci\u00f3n a un loop de todos los t\u00e9rminos de orden o(p2) y o(p0). Se discute la implementaci\u00f3n del contaje en potencias de nc en todo el lagrangiano. las dos expansiones quiral y en potencias de 1\/nc se consideran del mismo orden . el matching con la teor\u00eda su(3) se obtiene a trav\u00e9s de la integraci\u00f3n del campo m\u00e1s masivo hasta correcciones de un loop. Ello permite realizar una estimaci\u00f3n de algunos de los par\u00e1metros de la nueva teor\u00eda en t\u00e9rminos de los par\u00e1metros bien conocidos de su(3). se calculan las masas y constantes de desintegraci\u00f3n de las nueve part\u00edculas de la teor\u00eda a primer y segundo orden en la expansi\u00f3n en , primero en el l\u00edmite de isosp\u00edn y despu\u00e9s a primer orden en . Los resultados, que incluyen la determinaci\u00f3n de los par\u00e1metros y el \u00e1ngulo de mezcla , son satisfactorios. las siguientes desintegraciones son analizadas a primer y segundo orden en , en el marco de la teor\u00eda de nonete: se mejora el resultado a nivel \u00e1rbol de su(3) gracias a la inclusi\u00f3n de la mezcla de la y la , pero los efectos de las interacciones de los estados finales siguen jugando un papel esencial en el proceso; a primer orden, los resultados tienen el orden de magnitud correcto, pero, aparentemente, la expansi\u00f3n de bajas energ\u00edas falla cuando se a\u00f1aden las correcciones de segundo orden; y la teor\u00eda proporciona una descripci\u00f3n muy buena de la transici\u00f3n.<\/p>\n
