| Popis: | The fluctuations of five-dimensional self-gravitating non-Abelian kinks which arise from the breaking of the $SU(5)\ifmmode\times\else\texttimes\fi{}{Z}_{2}$-symmetric theory are analyzed within the context of braneworlds. While tensor and vector sectors of these fluctuations behave like its counterparts in the standard Abelian ${Z}_{2}$ kinks, the mixing between the field excitations of the non-Abelian kink and the scalar components of the metric makes the pure scalar sector of the theory very interesting. The spectrum of these scalar fluctuations, which includes gravitationally trapped massless modes on the core of the wall associated with the broken symmetries, is discussed for the two classes of kinks that break $SU(5)$ into its maximal subgroups. |
