Vanishing of the Cosmological Constant in Stabilized Quantum Gravity

Abstract

It is shown that the probability distribution $P(\lambda )$ for the effective cosmological constant is sharply peaked at $\lambda =0$ in stochastic (or "fifth-time") stabilized quantum gravity. The effect is similar to the Baum-Hawking mechanism, except that it comes about due to quantum fluctuations, rather than as a zeroth-order (in $\hslash$) semiclassical effect.
