  We calculate the anomalous dimensions of the next-to-leading order dijet
operators in soft-collinear effective theory (SCET). We use a formulation of
SCET where the Lagrangian is multiple copies of QCD and the interactions
between sectors occur through light-like Wilson lines in external currents. We
introduce a small gluon mass to regulate the infrared divergences of the
individual loop diagrams in order to properly extract the ultraviolet
divergences. We discuss this choice of infrared regulator and contrast it with
the $\delta$-regulator. Our results can be used to increase the theoretical
precision of the thrust distribution.
