Energy density in general relativity: a possible role for cosmological constant

TL;DR

This paper explores how a radially dependent cosmological constant within general relativity influences the energy density of an electron, using a static charged anisotropic fluid model.

Contribution

It introduces a scalar variable for the cosmological constant dependent on radius and investigates its impact on electron energy density within a relativistic framework.

Findings

Energy density of electron depends on the variable mbda.

The model suggests a potential role of mbda in particle physics.

The approach links cosmological concepts with microscopic particle properties.

Abstract

We consider a static spherically symmetric charged anisotropic fluid source of finite physical radius (\sim 10^{-16} cm) by introducing a scalar variable \Lambda dependent on the radial coordinate r under general relativity. From the solution sets a possible role of the cosmological constant is investigated which indicates the dependency of energy density of electron on the variable \Lambda.
