Abstract
By considering the coupling of two abelian gauge fields to pseudoscalar torsion we demonstrate that three different rotated polarized waves result for propagation over cosmological distances in a torsion field with constant gradient. It is also demonstrated that one of the waves is twice as intense as the other two providing us with a signature to identify the above coupling.
Keywords: Gauge fields; torsion; polarization rotation.
Resumen
Considerando el acoplamiento de dos campos de norma abelianos con la torsión seudoescalar, demostramos que tres distintas ondas giradas y polarizadas parecen propagarse sobre distancias cosmológicas en un campo de torsión con gradiente constante. También pretendemos demonstrar que una de estas ondas tiene una intensidad doble con respecto a las otras dos, lo que nos proporciona la oportunidad de identificar dicho acoplamiento.
Descriptores: Campo de norma; torsión; polarización rotación.
