Description
I will review recent advances in soft-collinear effective theory, focussing on two frontiers: The derivation of factorization theorems beyond the leading order in the power expansion, and the establishment of a factorization theorem for jet processes at hadron colliders. The main challenge in the first case concerns the treatment of endpoint-divergent convolution integrals, which arise when factorization is applied at next-to-leading power in scale ratios. In the second case, so-called “super-leading logarithms” arise in higher orders of perturbation theory, whose resumption has now been accomplished for the first time, 16 years after their discovery. As concrete examples, I will discuss applications in Higgs physics and rare decays of B mesons.
