Description
We propose a dynamical mechanism of vacuum energy cancellation by a scalar field $\phi$ coupled to curvature scalar as $\beta R \phi^2 f(\phi)$ where $f(\phi)$ is a polynomial function of $\phi$. It is shown that the exponential expansion driven by vacuum energy is dynamically transformed into the standard cosmological evolution of a radiation-dominated universe.
