Coleman Weinberg potential and creation of boson particles at the JNW wormhole spacetime

Abstract

This work is dedicated to investigate effects of the Coleman Weinberg self-interaction potential of quantum massless Klein Gordon (KG) scalar fields on perturbation of a minimally coupled Janis–Newman–Winicour (JNW) spherically symmetric static curved spacetime with traversable wormhole topology. In this way, we calculate the corresponding Hawking temperature, rate of particles production, radiation energy density, luminosity, particle absorption factor, mass loss and transmission probability via WKB approximation. This work is extension of the recently published work addressed in the reference section, in which we studied effects of free massive KG quantum waves to find same quantities above for the JNW spacetime with singular naked topology. In fact the JNW spacetime has singular naked with real scalar charge but is traversable wormhole topology with imaginary scalar charge.
