Abstract

We study semi-classical rotating open strings ending on a probe Dp-brane close to a stack of extremal, non-extremal Dp-branes and Dp-branes with Bfields. These states may be interpreted as positronium-like bound states of spinning W-bosons in an SU(N + 1) → SU(N)× U(1) theory. In each case, we describe the behaviour of the strings and examine the relation… (More)
