Semi-inclusive jet cross sections within SCET

Understand

We review the definition of semi-inclusive jet functions within Soft Collinear Effective Theory (SCET) and their application to inclusive jet cross sections.

• As an example, we consider both the inclusive production of jets and the jet fragmentation function in proton-proton collisions.
• The 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 $(\alpha_s \ln R)^n$ can be achieved.
