  We find both analytical and numerical solutions of SU(2) Yang-Mills with an
adjoint Higgs field within both closed and open tubes whose sections are
spherical caps. This geometry admits a smooth limit in which the space-like
metric is flat and, moreover, allows one to use analytical tools which in the
flat case are not available. Some of the analytic configurations, in the limit
of vanishing Higgs coupling, correspond to magnetic monopoles and dyons living
within this tube-shaped domain. However, unlike what happens in the standard
case, analytical solutions can also be found in the case in which the Higgs
coupling is non-vanishing. We further show that the system admits long-lived
breathers.
