We review the denition of semi-inclusive jet functions within Soft Collinear Eective Theory

(SCET) and their application to inclusive jet cross sections. We consider the fully inclusive

production cross section of jets as well as several jet substructure observables in proton-proton

collisions relevant for the LHC and RHIC. The corresponding semi-inclusive jet functions satisfy

renormalization group (RG) equations which take the form of standard timelike DGLAP evolution

equations, analogous to collinear fragmentation functions. By solving these RG equations, the

resummation of potentially large single logarithms n

s lnn R can be achieved. We present numerical

results at NLO+NLLR accuracy and compare to the available data.
