Findings

Gravity achieves mass renormalization for Kerr particles.

A regularized Kerr-Newman solution with a vacuum-filled bag is proposed.

Gravity influences phase transitions inside the bag, stabilizing the system.

Abstract

On the basis of the Kerr spinning particle, we show that the mass renormalization is perfectly performed by gravity for an arbitrary distribution of source matter. A smooth regularization of the Kerr-Newman solution is considered, leading to a source in the form of a rotating bag filled by a false vacuum. It is shown that gravity controls the phase transition to an AdS or dS false vacuum state inside the bag, providing the mass balance.
