Bound states in monopoles: sources for UHECR ?
E. Huguet, P. Peter
Abstract
Bound states in monopoles are studied through a simplified, Witten-like model. As the overall structure is determined in full details, it is shown in particular that only those states having a vanishing angular momentum are allowed; for those, the energy spectrum is derived numerically and an approximation is set up that allows an easy description in terms of wavefunctions, usefull for further applications. The monopoles are then proposed as candidates of ultra high energy cosmic rays, an hypothesis that should soon be testable through the Pierre Auger Observatory.
