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…
Nonperturbative corrections to moments of the decay B -> X_s l^+ l^-
Christian W. Bauer, Craig N. Burrell
We study nonperturbative corrections to the inclusive rare decay B -> X_s l^+ l^- by performing an operator product expansion (OPE) to O(1/m_b^3). The values of the matrix elements…
Nonperturbative corrections to B -> X_s l^+ l^- with phase space restrictions
Christian W. Bauer, Craig N. Burrell
We study nonperturbative corrections up to O(1/m_b^3) in the inclusive rare B decay B -> X_s l^+ l^- by performing an operator product expansion. The values of the matrix elements…
