Scalar-tensor theory with enhanced gravitational effects

TL;DR

This paper explores a modified scalar-tensor gravitational theory combining Brans-Dicke and Bekenstein interactions, revealing solutions with significantly amplified gravitational effects that could be tested experimentally.

Contribution

It introduces a novel scalar-tensor model with enhanced gravitational effects due to combined interactions, differing from standard theories.

Findings

Solutions exhibit highly amplified gravitational effects.

Potential for laboratory tests of the modified theory.

Distinct from predictions of General Relativity.

Abstract

It is shown that a Brans-Dicke scalar-tensor gravitational theory, which also includes Bekenstein's kind of interaction between the Maxwell and scalar fields, has a particular kind of solutions with highly enhanced gravitational effects as compared with General Relativity, prone to laboratory tests.
