QCD Factorization and SCET at NLO
Alexander R. Williamson
In this article we review recent advances in the area of QCD factorization. We begin with a brief outline of QCD factorization, as well as a description of some recent results rega…

Towards the Anomalous Dimension to Order Lambda_QCD/m_b for Phase Space Restricted B --> X(u) ell anti-nu and B --> X(s) gamma
Michael Trott, Alexander R. Williamson
We examine the anomalous dimension matrix appropriate for the phase space restricted B --> X(u) ell anti-nu and B --> X(s) gamma decay spectra to subleading nonperturbative order.…

Phenomenology of B -> pi pi, pi K Decays at O(alpha^2 beta_0) in QCD Factorization
Craig N. Burrell, Alexander R. Williamson
We study O(alpha^2 beta_0) perturbative corrections to matrix elements entering two-body exclusive decays of the form B -> pi pi, pi K in the QCD factorization formalism, including…
