Abstract

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 M-W and m(t) in the W+W- and <t(t)over bar> threshold legions. 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 Delta m(t) = 200 MeV for fixed M-W would constrain a 100GeV SM Higgs boson mass within about +/-2 GeV, while Delta M-W = 6 MeV for fixed m(t) would constrain m(h) to about +/-10 GeV.
