Abstract

We study the self-interaction of a massive scalar field with a point-like particle in a Kerr resp. Schwarzschild background black hole space-times. We find that in addition to regularization of the self-field a finite renormalization of the particle mass is also necessary to obtain a unique equation of motion. We expand the renormalized equation of motion for large scalar masses and apply this approximation for the neutral pion radiation by protons in the strong electromagnetic field of a magnetar. Our results show that taking into account general relativistic effects to leading order has a significant influence on the proton energy and the intensity of neutral pion radiation.
