Zero-bin subtractions are required to avoid double counting soft contributions in collinear loop integrals in soft-collinear effective theory (SCET). In traditional approaches to factorization, double counting is avoided by dividing jet functions by matrix elements of soft Wilson lines. In this paper, we compare the two approaches to double counting, studying the quark form factor and deep inelastic scattering (DIS) as ${x}_{B}\ensuremath{\rightarrow}1$ as examples. We explain how the zero-bin…

Soft-Collinear Factorization and Zero-Bin Subtractions
We study the Sudakov form factor for a spontaneously broken gauge theory using a (new) {delta}-regulator. To be well defined, the effective theory requires zero-bin subtractions for the collinear
Removing phase-space restrictions in factorized cross sections
Factorization in gauge theories holds at the amplitude or amplitude-squared level for states of given soft or collinear momenta. When performing phase-space integrals over such states, one would

It is concluded that a consistent description of the factorization for F1 implies the end-point collinear divergencies in the hard and soft spectator contributions, i.e. convolution integrals with respect to collinoid fractions are not well defined.
