't Hooft-Polyakov monopole of higher generalized angular momenta

Abstract

We recall the quaternionic fomulation, which can simplify the computation of the linearized Yang-Mills-Higgs equation in the background of a 't Hooft-Polyakov monopole. We then study the solutions in the cases $j=0$, $j=1$ and $j\geq 2$ separately. In particular, we investigate the spectral properties of the monopoles. We focus on some of the bound states and show that as the generalized momentum increases, the $k-$th eigenvalue tends to 1. We show the existence of Feshbach resonance for \om <1 in the coupled system and calculated the partial cross section when \om >1.Comment: 20 pages, 3 figures and 4 table
