An effective field theory for collinear and soft gluons: heavy to light decays
Christian W. Bauer, Sean Fleming, Dan Pirjol +1
We construct the Lagrangian for an effective theory of highly energetic quarks with energy Q, interacting with collinear and soft gluons. This theory has two low energy scales, the…
Summing Sudakov logarithms in B -> X_s + gamma in effective field theory
C. W. Bauer, S. Fleming, M. Luke
We construct an effective field theory valid for processes in which highly energetic light-like particles interact with collinear and soft degrees of freedom, using the decay B ->…
A Model Independent Determination of |V_{ub}|
Christian W. Bauer, Zoltan Ligeti, Michael Luke
It is shown that measuring the lepton invariant mass spectrum in inclusive semileptonic B -> X_u l nu decay yields a model independent determination of |V_{ub}|. Unlike the lepton…
