Anthropic prediction for a large multi-jump landscape
Abstract
The assumption of a flat prior distribution plays a critical role in the anthropic prediction of the cosmological constant. In a previous paper we analytically calculated the distribution for the cosmological constant, including the prior and anthropic selection effects, in a large toy ``single-jump'' landscape model. We showed that it is possible for the fractal prior distribution we found to behave as an effectively flat distribution in a wide class of landscapes, but only if the single jump size is large enough. We extend this work here by investigating a large () toy ``multi-jump'' landscape model. The jump sizes range over three orders of magnitude and an overall free parameter determines the absolute size of the jumps. We will show that for ``large'' the distribution of probabilities of vacua in the anthropic range is effectively flat, and thus the successful anthropic prediction is validated. However, we argue that for small , the distribution may not be smooth.
