Generalised scalar-tensor theory and the cosmic acceleration

Abstract

In this paper it has been shown that a simple functional form of $\omega (\varphi )$ in a generalised scalar tensor theory can drive the present cosmic acceleration without any quintessence field or the cosmological constant $\Lambda$. Furthermore, it ensures a smooth transition from a decelerated to an accelerated phase of expansion in the matter dominated regime.
