      abstract = {The Top Yukawa coupling profoundly influences several core  mysteries linked to the electroweak scale and the Higgs  boson. We study the feasibility of measuring the Top Yukawa  coupling at high energy muon colliders by examining the  high energy dynamics of the weak boson fusion to top quark  pair processes. A deviation of the Top Yukawa coupling from  the Standard Model would lead to a modified  $VV→t\overline{t}$ process, violating unitarity at high  energy. Our analysis reveals that utilizing a muon collider  with a center-of-mass energy of 10 TeV and an integrated  luminosity of $10ab^-1$ allows us to investigate the Top  Yukawa coupling with a precision surpassing 1.5%, more than  one order of magnitude better than the precision from  $t\overline{t}h$ channel at muon colliders. This precision  represents a notable enhancement compared to the  anticipated sensitivities of the High-Luminosity LHC (3.4%)  and those at muon colliders derived from the  $t\overline{t}H$ process.},
