Tom Rudelius (UCB) “Sharpening the Distance Conjecture in Diverse Dimensions”
–
Abstract: The Distance Conjecture holds that any infinite-distance limit in the scalar field moduli space of a consistent theory of quantum gravity must be accompanied by a tower of light particles whose masses scale exponentially with proper field distance $||\phi||$ as $m \sim \exp(- \lambda ||\phi||)$, where $\lambda$ is order-one in Planck units. While the evidence for this conjecture is formidable, … Read More
