Stars of WIMPs

TL;DR

This paper analyzes boson-fermion stars composed of WIMPs, showing their low-energy behavior aligns with leptonic sector particles in the minimal supersymmetric standard model, with effective coupling linked to the Fermi constant.

Contribution

It introduces a model of boson-fermion stars interacting via a U(1) current-current term, connecting their behavior to WIMPs in supersymmetric theories.

Findings

Describes the low-energy behavior of WIMP-based boson-fermion stars.

Establishes a relation between the effective coupling constant and the Fermi constant.

Provides a theoretical framework linking astrophysical objects to particle physics models.

Abstract

A class of boson-fermion stars, whose spin-0 and spin-1/2 constituents interact through a U(1) current-current term in the Lagrangian density, is analysed. It is shown that it describes the low-energy behavior of a system of weakly interacting massive particles (WIMPs) from the leptonic sector of the minimal supersymmetric standard model. In this case the effective coupling constant $\lambda$ is related to the Fermi constant $G_F$.
