56. $B_c \to \eta_c$ form factors at large recoil: interplay of soft-quark and soft-gluon double logarithms

Dennis Horstmann (Siegen University)

Talk

At next-to-leading power, predictions in Soft-Collinear Effective Theory often suffer from a technical problem, known as endpoint-divergent convolution integrals. While this problem has recently been overcome for some processes, these methods are currently limited to examples with non-recursive refactorsation identities. As I will show in this talk, exclusive heavy-to-light transition form...

57. Factorization and Resummation for Sequential Recombination Jet Cross Section

Jürg Haag (UZH)

Talk

We extend the class of factorization theorems for non-global observables from fixed angular constraints to cross sections defined in terms of sequential jet clustering. The associated hard and soft functions depend not only on the directions of the hard partons, but also on their energy fractions. We derive the one-loop anomalous dimension of the hard functions that drives the...
