Abstract

Within modified gravity, we study static spherically and axially symmetric self-gravitating non-Abelian monopoles in $SU(2)$ Yang-Mills-Higgs theory. By comparing these monopoles with those obtained in Einstein-Yang-Mills-Higgs theory, we identify the differences introduced by the modification of gravity and show that they can be quite significant for systems with strong Higgs self-coupling.
