  In our recent paper, we have investigated the potential for the LHC to
discover vector-like quark partner states singly produced via their
chromomagnetic moment interactions. These production mechanisms extend
traditional searches which rely on pair-production of top-quark partner states
or on the single production of these states through electroweak interactions,
in the sense of providing greatly increased reach in parameter space regions
where traditional searches are insensitive. In this study we determine the
potential of both the 14 TeV high-luminosity LHC (HL-LHC) and a 100 TeV
proton-proton collider to probe new vector-like quarks produced in this mode.
We focus on the single production of a top-quark partner in association with an
ordinary top-quark, as well as on the resonant production of the bottom-quark
partner with its subsequent decay to a top-quark partner and a $W$ boson. For
both cases we consider a top-partner decay to the Higgs boson and an ordinary
top-quark. We find that HL-LHC and a future 100 TeV proton collider can probe
vector-like partner masses up to about 3 TeV and 15-20 TeV respectively,
visibly extending the range of the traditional vector like quark partner
searches.
