title: "Figure 14(c)" of "Search for pair- and single-production of vector-like quarks in final states with at least one $Z$ boson decaying into a pair of electrons or muons in $pp$ collision data collected with the ATLAS detector at $\sqrt{s} = 13$ TeV"

description: Expected 95$\%$ CL lower limits from the combination of the pair-production channels on the mass of vector-like quarks for all combinations of BRs for $B\rightarrow Zb$, $B\rightarrow Hb$, $B\rightarrow Wt$, adding up to unity.
description: CERN-LHC, ATLAS. A search for vector-like quarks is presented, which targets their decay into a $Z$ boson and a third-generation Standard Model quark. In the case of a vector-like quark $T$ ($B$) with charge $+2/3e$ ($-1/3e$), the decay searched for is $T \rightarrow Zt$ ($B \rightarrow Zb$). Data for this analysis were taken during 2015 and 2016 with the ATLAS detector at the Large Hadron Collider and correspond to an integrated luminosity of 36.1 fb$^{-1}$ of $pp$ collisions at $\sqrt{s}=13$ TeV. The final state used is characterized by the presence of $b$-tagged jets, as well as a $Z$ boson with high transverse momentum, which is reconstructed from a pair of opposite-sign same-flavor leptons. Pair- and single-production of vector-like quarks are both taken into account and are each searched for using optimized dileptonic exclusive and trileptonic inclusive event selections. In these selections, the high scalar sum of jet transverse momenta, the presence of high-transverse-momentum large-radius jets, as well as - in the case of the single-production selections - the presence of forward jets are used. No significant excess over the background-only hypothesis is found and exclusion limits at 95% confidence level allow masses of vector-like quarks of $m_T &gt; 1030$ GeV ($m_T &gt; 1210$ GeV) and $m_B &gt; 1010$ GeV ($m_B &gt; 1140$ GeV) in the singlet (doublet) model. In the case of 100% branching ratio for $T\rightarrow Zt$ ($B\rightarrow Zb$), the limits are $m_T &gt; 1340$ GeV ($m_B &gt; 1220$ GeV). Limits at 95% confidence level are also set on the coupling to Standard Model quarks for given vector-like quark masses.

description: Upper limits at 95$\%$ CL on the cross section times BR to $Zt$ of single production (SP) of a $T$-quark. The expected limits are shown for the combination of the channels, as are the observed limits. The expected cross section times BR to $Zt$ for single-$T$-quark production is also shown for a coupling $\kappa_T = 0.5$, which corresponds to a coupling of $c_W = \sqrt{c^2_{W,L} + c^2_{W,R}} = 0.45$ from Ref. [14]. The BR assumed here corresponds to the singlet benchmark model, i.e. $\approx 25\%$.
