Abstract
In recent years, exploring beyond the Standard Model scenarios involving an additional non-Abelian hidden gauge group has been of increasing interest. This sector, which would contain dark quarks and dark gluons, could provide dark matter candidates in the form of stable dark hadrons, leading to very peculiar signatures at colliders that have not yet been thoroughly explored. We will discuss such signatures, and go into the details of the search for a new 𝑍’ resonance decaying into a pair of dark quarks which hadronise into dark hadrons before promptly decaying back as Standard Model particles. This analysis is based on data recorded at √𝑠 = 13 TeV with the ATLAS detector at the Large Hadron Collider between 2015 and 2018, corresponding to an integrated luminosity of 139 fb−1.
