Abstract:

The Next Linear Collider(NLC) will provide a excellent tool for probing the detailed nature of the top quark. By extending the recent analysis of Dokshitzer, Khoze and Sterling, we perform a preliminary examination of the influence of an anomalous chromomagnetic moment for the top,

\kappa

, on the spectrum of gluon radiation associated with

t\bar t

production. In particular, we analyze the sensitivity of future data to non-zero values of

\kappa

and estimate the limits that can be placed on this parameter at the NLC with center of mass energies

\sqrt {s}=

500 and 1000 GeV.
