Curvature Oscillations in Modified Gravity and High Energy Cosmic Rays

TL;DR

This paper explores how F(R)-modified gravity theories cause curvature oscillations in astrophysical systems, potentially producing high-energy cosmic rays observable as a consequence of these oscillations.

Contribution

It demonstrates that F(R) gravity models induce high-frequency curvature oscillations that can generate energetic cosmic rays, a novel link between modified gravity and cosmic ray phenomena.

Findings

Curvature oscillations occur in F(R) gravity with rising energy density.

Oscillations can have high frequency and amplitude.

Potential production of energetic cosmic rays from these oscillations.

Abstract

It is shown that F(R)-modified gravitational theories lead to curvature oscillations in astrophysical systems with rising energy density. The frequency and the amplitude of such oscillations could be very high and would lead to noticeable production of energetic cosmic ray particles.
