LHC phenomenology of dark matter with a color-octet partner

Colored darksectors where the darkmatter particle is accompanied by colored partners have recently attracted theoretical and phenomenological interest. We explore the possibility that the darksector consists of the darkmatter particle and a color- octetpartner, where the interaction with the Standard Model is governed by an effective operator involving gluons. The resulting interactions resemble the color analogues of electric and magnetic dipolemoments. Although many phenomenological features of this kind of model only depend on the group representationof the partner under SU(3)$_c$, we point out that interesting collider signatures such as $ R$- hadronsare indeed controlled by the interaction operator between the darkand visible sector. We perform a study of the current constraints and future reach of LHC searches, where the complementarity between different possible signals is highlighted and exploited.
