Mi objetivo en este trabajo es argumentar que es posible establecer una asimetría temporal en teoría cuántica de campos independientemente de los argumentos derivados de considerar la violación de CP y por lo tanto T en interacciones débiles, e independientemente de que las ecuaciones dinámicas de la teoría sean invariantes ante inversión temporal. En particular, argumentaré que la asimetría temporal se sigue a partir del análisis del grupo de simetría propio de la teoría y sus vínculos con la ontología: los mismos argumentos que se aplican para establecer cuáles son las entidades invariantes y con significado físico dentro de la teoría, se pueden utilizar para establecer una asimetría temporal.Referências
