  "abstract": "We present an overview of the sensitivity of a muon collider to the flavor-diagonal electroweak couplings of the top quark, using dimension-six operators of the Warsaw basis. Of the nine fermion-boson operators involving the top quark, the bounds on three are not competitive with existing limits, and we focus on the remaining six. We estimate individual $95\\%$ CL limits on the corresponding Wilson coefficients at $\\sqrt{s} = 3$, $6$, $10$, and $14$~TeV from $2σ$ statistical cross-section uncertainties, and assess the effect of an assumed systematic uncertainty. We consider six top-quark production modes: $t\\bar t$, $t \\bar t h$, $t \\bar t ν\\bar ν$, $t \\bar t μ^+ μ^-$, single-top $t\\bar b μ^- \\bar ν_μ$, and single-top-plus-Higgs, the last three for several rapidity coverages of the final-state muons. The $s$-channel $t\\bar t$ and $t\\bar t h$ processes give the strongest sensitivity to the electroweak dipole couplings, with allowed intervals narrower than the current LHC ones by factors of about $3$ to $6$ at $\\sqrt{s} = 3$ and $6$ TeV, and by an order of magnitude or more at $10$ and $14$ TeV. The left- and right-handed $ttZ$ couplings, as well as the Yukawa $tth$ couplings (for $\\sqrt{s} \\geq 6$ TeV), are best probed in $t \\bar t ν\\bar ν$ production, while the right-handed $tbW$ coupling is best probed in single-top production. For the $ttZ$ and $tbW$ couplings, the limits improve on the current LHC bounds by factors from about $1.5$ to more than an order of magnitude. Our results agree with previous analyses of the Yukawa and the dipole couplings, and provide a roadmap for more in-depth studies.",
