title: "Figure 8b (Lower 68 expected exclusion contour 4)" of "Search for resonant production of strongly coupled dark matter in proton-proton collisions at 13 TeV"

description: The lower 68% expected exclusion for the nominal $\text{Z}^{\prime}$ cross section.
description: The first collider search for dark matter arising from a strongly coupled hidden sector is presented, using a data sample corresponding to $138\,\text{fb}^{-1}$, collected with the CMS detector at the CERN LHC, at a center-of-mass energy of $13\,\text{TeV}$. The hidden sector is hypothesized to couple to the standard model (SM) via a heavy leptophobic $\text{Z}^{\prime}$ mediator, which would be produced as a resonance in proton-proton collisions. The mediator decay results in two "semivisible" jets, containing both visible matter and invisible dark matter. The final state therefore includes moderate missing energy aligned with one of the jets, a signature ignored by most dark matter searches. The observed dijet transverse mass spectra are smoothly falling, as expected from the SM; no structure compatible with the signal is observed. Assuming the $\text{Z}^{\prime}$ and SM Z bosons have the same couplings to the SM quarks, an inclusive search, relevant to any model that exhibits this kinematic behavior, excludes mediator masses of 1.5--$4.0\,\text{TeV}$ at 95% confidence level, depending on the other signal model parameters. To enhance the sensitivity of the search for this particular class of hidden sector models, a boosted decision tree (BDT) is trained using jet substructure variables to distinguish between semivisible jets and SM jets from background processes. When the BDT is employed to identify each jet in the dijet system as semivisible, the mediator mass exclusion increases to $5.1\,\text{TeV}$, for wider ranges of the other signal model parameters.
