摘要：

We consider the generalized particle dynamics, that we proposed [S. Das et al., J. High. Energy Phys. 0904 (2009) 115] in braneworld formalisms for an asymptotically anti-de Sitter background. The present framework results in a new model that accounts for the late acceleration of the universe. An effective dark energy equation of state, exhibiting a phantom-like behavior, is generated. The model is derived by embedding the physical FLRW universe in a (4 + 1)-dimensional effective spacetime, induced by the generalized particle dynamics. We corroborate our results with present-day observed cosmological parameters.
