Maths HEP Lunchtime Seminars: "Brane Worlds: non-Z_2 symmetry, acausality and the radion"

Presented by Ian Vernon,

22 November 2002 13:00 in CM221

"I will describe some of the rich phenomenology which is to be found in brane world scenarios. Initially, some of the seminal models will be outlined and their generalisations discussed. The unusual cosmology of a brane world model will be examined and shown to be in most cases in agreement with current observations. The effect of relaxing the Z_2 symmetry found in most models will be discussed, as will the apparent acausality experienced by a brane based observer. Then the general non-linear equation for the (cosmological) radion will be derived and examined to determine the complete behaviour of the interbrane distance. "
