4.3 Top Quark Mass Measurement
The top quark mass can also be determined from direct reconstruction of
Dilepton events at JLC, in addition
to the mass determination from the
CDF and D0 have determined the top quark mass to be
GeV/c2 from direct reconstruction of
The top quark mass is expected to be determined to a precision
of 1 to 2 GeV/c2 at the Tevatron and the LHC.
For direct reconstruction, the Dilepton channel has the
smallest systematic uncertainty, in comparison with the Lepton + Jets
and Multi-jet channels.
In contrast to the hadron colliders, the beam energy at the
Linear Collider provides constraints in the kinematic reconstruction.
A precision of 200 MeV/c2 on the top quark mass can be achieved
at JLC .
