A Lorentz Invariance Violating Cosmology on the DGP Brane

TL;DR

This paper explores a cosmological model based on a DGP braneworld scenario that incorporates Lorentz invariance violation, scalar and vector fields, explaining late-time acceleration and phantom phase transition.

Contribution

It introduces a novel Lorentz-violating DGP-inspired model with scalar and vector fields to explain late-time cosmic acceleration.

Findings

Model accounts for late-time acceleration.

Transition to phantom phase achieved.

Parameter space supports observational consistency.

Abstract

We study cosmological implications of a Lorentz invariance violating DGP-inspired braneworld scenario. A minimally coupled scalar field and a single, fixed-norm, Lorentz-violating timelike vector field within an interactive picture provide a wide parameter space which accounts for late-time acceleration and transition to phantom phase of the scalar field.
