Axially symmetric Proca-Higgs boson stars

Abstract

We consider strongly gravitating configurations consisting of coupled real Higgs scalar field and vector (Proca) field of mass µ. For such a system, we find static regular axially symmetric solutions describing asymptotically flat configurations which may be referred to as Proca-Higgs mini-boson stars, since their total mass and spatial dimension are of order M 2 Pl /µ and µ −1 , respectively. The system possesses an axially symmetric dipole field and may be regarded as a Proca dipole.

Investigations focusing on the non-relativistic regime are detailed in [45][46][47][48].…”
