We construct a complete and minimal basis of subleading-power N-jet operatorsin position-space soft-collinear effective theory (SCET) and discuss how theLow-Burnett-Kroll amplitude is recovered in this framework. We begin asystematic investigation of the anomalous dimension of next-to-leading powerN-jet operators in view of resummation of logarithmically enhanced terms inpartonic cross sections and discuss the explicit result at the one-loop orderfor fermion-number two N-jet operators at the second order in the powerexpansion parameter of SCET.
