On the Gluon Regge Trajectory in $O(\alpha_s^2)$
  We recalculate the gluon Regge trajectory in next-to-leading order to clarify a discrepancy between two results in the literature on the constant part. We confirm the result obtained by Fadin et al.~\cite{FFK}. The effects on the anomalous dimension and on the $s^{\omega}$ behavior of inclusive cross sections are also discussed.
