Phys. Rev. D 56, 1714–1722 (1997)Precision W-boson and top-quark mass determinations at a muon colliderReceived 18 February 1997; published in the issue dated 1 August 1997 Precise determinations of the masses of the W boson and of the top quark could stringently test the radiative structure of the standard model (SM) or provide evidence for new physics. We analyze the excellent prospects at a muon collider for measuring MW and mt in the W+W- and tt̅ threshold regions. With an integrated luminosity of 10 (100) fb-1, the W-boson mass could be measured to a precision of 20 (6) MeV, and the top-quark mass to a precision of 200 (70) MeV, provided that theoretical and experimental systematics are understood. A measurement of Δmt=200 MeV for fixed MW would constrain a 100 GeV SM Higgs boson mass within about ±2 GeV, while ΔMW=6 MeV for fixed mt would constrain mh to about ±10 GeV. © 1997 The American Physical Society URL:
