NNLO corrections to B --> X_u l nu and the determination of |V_ub|
Ben D. Pecjak
The calculation of partial decay rates in B --> X_u l nu decays at next-to-next-to-leading order (NNLO) in alpha_s and to leading order in 1/m_b is described. New results for the h…
Theory Review of Exclusive Rare Radiative Decays
Ben D. Pecjak
I briefly review the theory status of exclusive rare radiative decays.
Towards Decays at NNLO in SCET
Ahmed Ali, Ben D. Pecjak, Christoph Greub
We compute NNLO () corrections to the hard-scattering kernels entering the QCD factorization formula for decays, where is a light vector meson. We gi…
Analyzing B_s - bar B_s mixing: Non-perturbative contributions to bag parameters from sum rules
T. Mannel, B. D. Pecjak, A. A. Pivovarov
We use QCD sum rules to compute matrix elements of the Delta B=2 operators appearing in the heavy-quark expansion of the width difference of the B_s mass eigenstates. Our analysis…
