Abstract

We consider some fundamental constants from the point of view of the duality symmetry. Our analysis of duality is focused on three issues: the maximum radiated power of gravitational waves, the cosmological constant, and the magnetic monopole mass. We show that the maximum radiated power of gravitational waves implies that the Planck time is a minimal time. Furthermore, we prove that duality implies a quantization of the cosmological constant. Finally, by using one of the Euler series for the number π, we show that the Dirac electric–magnetic charge quantization implies a mass for the magnetic monopole (or neutrino) of the order of 10^–5 the mass of the electron.

Keywords: Fundamental constants; gravitational waves; cosmological constant; duality.

Resumen

Consideramos algunas constantes fundamentales desde el punto de vista de la simetría de dualidad. Nuestro análisis de dualidad se enfoca en tres temas: la potencia máxima radiada de ondas gravitacionales, la constante cosmológica y la masa del monopolo magnético. Demostramos que la potencia máxima radiada de ondas gravitacionales implica que el tiempo de Planck corresponde a un tiempo mínimo. Mas aún, probamos que la dualidad implica una cuantización de la constante cosmológica. Finalmente, usando una de las series de Euler para el numero π, demostramos que la cuantización de la carga eléctrica–magnética de Dirac implica una masa para el monopolo magnético (o neutrino) del orden de 10^–5 la masa del electrón.

Descriptores: Constantes fundamentales; ondas gravitacionales; constante cosmológica; dualidad.
