      abstract     = {A search for emerging jets is presented using 51.8
                      fb$^{-1}$ of proton-proton collision data at $\sqrt{s} =
                      13.6$ TeV, collected by the ATLAS experiment during 2022 and
                      2023. The search explores a hypothetical dark sector
                      featuring 'dark quarks', which are charged under a confining
                      gauge group and couple to the Standard Model via a new
                      mediator particle. These dark quarks undergo showering and
                      hadronization within the dark sector, forming long-lived
                      dark mesons that decay back into Standard Model particles.
                      This results in jets which contain multiple displaced
                      vertices known as emerging jets. The analysis targets events
                      with pairs of emerging jets, produced either through a
                      vector mediator, $Z'$, in the $s$-channel, or a scalar
                      mediator, $\Phi$, in the $t$-channel. No significant excess
                      over the Standard Model background is observed. Assuming a
                      dark pion proper decay length between 5 and 50 mm, $Z'$
                      mediator masses between 600 and 2550 GeV are excluded for
                      quark and dark quark coupling values of 0.01 and 0.1,
                      respectively. For a quark-dark quark coupling of $0.1$,
                      $\Phi$ mediator masses between 600 and 1375 GeV are
                      excluded. These results provide the first direct constraints
                      on emerging jet pair production via a $Z'$ mediator, and
                      represent the first search to investigate emerging jet
                      production via $t$-channel exchange of a scalar mediator.},
