  "abstract": "We investigate the discovery potential of a singly produced vector-like top quark $T$ in the $T\\to tZ$ decay channel at future muon-proton ($μp$) colliders, considering three benchmark center-of-mass energies: $\\sqrt{s}=5.29$, $6.48$, and $9.16$~TeV. The baseline signal final state consists of a semileptonic top decay $t\\to bW\\to b\\ellν$ and a hadronic $Z\\to q\\bar{q}$ decay, where the collimated quark pair from the $Z$ boson is reconstructed as a single large-radius fat jet $J$. Full detector-level Monte Carlo simulations are performed for both the signal process and the dominant Standard Model backgrounds. We derive the $5σ$ discovery contours and the $95\\%$ confidence level exclusion limits in the two-dimensional parameter space spanned by the VLQ mass $m_T$ and the effective coupling $g^*$. A comparison with the $T\\to Wb$ channel and with searches at other collider facilities reveals that the $T\\to tZ$ decay mode provides complementary sensitivity and offers unique advantages for probing high-mass vector-like $T$ quarks in the boosted jet topology.",
