Total screening and finite range forces from ultra-massive scalar fields

TL;DR

This paper investigates forces between static particles coupled to an ultra-massive scalar field, revealing finite-range interactions and scalar charge screening effects.

Contribution

It introduces a model where scalar forces have finite range and particles are surrounded by screening clouds, a novel feature in scalar field theories.

Findings

Force vanishes beyond a finite distance between particles.

Particles are surrounded by compact scalar field clouds.

Scalar charge is completely screened by the field.

Abstract

Force between static point particles coupled to a classical ultra-massive scalar field is calculated. The field potential is proportional to the modulus of the field. It turns out that the force exactly vanishes when the distance between the particles exceeds certain finite value. Moreover, each isolated particle is surrounded by a compact cloud of the scalar field that completely screens its scalar charge.
