“Top-Quark Mass Measurements at D0”
The top quark is the heaviest fundamental particle discovered so far. The large mass of the top quark, corresponding to a Yukawa coupling to the Higgs boson equal to unity within the uncertainty, suggests a special role for the top quark in the breaking of electroweak symmetry. The interest in the top-quark mass also arises from the constraint imposed on the mass of the Higgs boson from the relationship among the values of the top-quark mass, Higgs-boson mass and the radiative corrections to the W-boson mass.
I will present the latest top-quark mass measurements by the D0 experiment at the Fermilab Tevatron proton-antiproton collider. I will also discuss future prospects of top-quark mass measurements.
