Spin precession in the Dvali-Gabadadze-Porrati braneworld scenario

TL;DR

This paper calculates the spin precession of a gyroscope in a braneworld gravity model, finding the effect is extremely small and currently undetectable, thus providing theoretical insights into multidimensional gravity effects.

Contribution

It derives the secular spin precession in the Dvali-Gabadadze-Porrati model, extending understanding of relativistic effects in multidimensional gravity scenarios.

Findings

Precession depends on central mass and orbit radius.

Effect size is too small for current detection.

Provides theoretical predictions for spin precession in braneworld models.

Abstract

In this letter we work out the secular precession of the spin of a gyroscope in geodesic motion around a central mass in the framework of the Dvali-Gabadadze-Porrati multidimensional gravity model. Such an effect, which depends on the mass of the central body and on the orbit radius of the gyroscope, contrary to the precessions of the orbital elements of the orbit of a test body, is far too small to be detected.
