The method of regions provides not only a systematic approach to computing Feynman integrals, but also useful information of formulating an EFT. For example, the SCET$_{\rm I}$ Lagrangian describing massless wide-angle scattering elegantly combines collinear and ultrasoft modes. This is grounded in the empirical observation that each loop in a pertinent region is either hard, collinear to an...
In this talk, I would like to present a derivation of the factorization formula for the impact-parameter dependent cross section using Soft-Collinear Effective Theory. Especially, this talk focuses on inclusive hard processes with only colorless final-state products in hadron and nuclear collisions. To describe Such processes, one only needs to replace the beam functions with the Fourier...
