Maths HEP Lunchtime Seminars: Dyon Death Eaters
15 February 2008 13:00 in CM221
I will describe and analyse general two-body decays of primitive and non-primitive 1/4-BPS dyons in four-dimensional type IIB string compactifications. For half-BPS decays, a relation is found between walls of marginal stability and the mathematics of Farey sequences and Ford circles. The relationship of marginal decay to the breakup of multi-centred dyons will also be discussed.
