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…
Two body B decays with isosinglet final states in SCET
Alexander R. Williamson, Jure Zupan
Expressions for decay amplitudes of B0, B- and Bs mesons to two light pseudoscalar or vector mesons, including isosinglet mesons eta, eta', omega, phi, are obtained using Soft Coll…
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…
Subleading shape function contributions to the hadronic invariant mass spectrum in B -> X_u l νdecay
Craig N. Burrell, Michael E. Luke, Alexander R. Williamson
We study the O(Lambda/mb) corrections to the singly and doubly differential hadronic invariant mass spectra dΓ/dsH and dΓ/dsH dq^2 in b -> u decays, and discuss the implications fo…
Renormalon Analysis of Heavy-Light Exclusive B Decays
Craig N. Burrell, Alexander R. Williamson
We study two-body exclusive decays of the form B -> D^(*) L (L = π, ρ) in the heavy quark limit. We perform a renormalon analysis of such processes to determine the order at which…
