| Abstract: | Topologically nontrivial solutions in the Georgi-Glashow model are studied. It is shown that only in quantum theory does an instanton exist as a stable field configuration. An effective action is constructed, and quantum equations of motion for the instanton are obtained on its basis. Their solutions at long and short distances are obtained. A critical size corresponding to a stable instanton in the Georgi-Glashow model is found. |
