Lectures on the Theory of Non-leptonic B Decays
Matthias Neubert
These notes provide a pedagogical introduction to the theory of non-leptonic heavy-meson decays recently proposed by Beneke, Buchalla, Sachrajda and myself. We provide a rigorous b…
Two-Loop Renormalization of Heavy--Light Currents at Order 1/m_Q in the Heavy-Quark Expansion
Thomas Becher, Matthias Neubert, Alexey A. Petrov
We present exact results, at next-to-leading order in renormalization-group improved perturbation theory, for the Wilson coefficients appearing at order 1/m_Q in the heavy-quark ex…
Enhanced Gluino Box Contribution to epsilon'/epsilon in SUSY
Matthias Neubert
We show that in supersymmetric extensions of the Standard Model gluino box diagrams can yield a large CP-violating Delta(I)=3/2 contribution to s->d+q(bar)+q flavor-changing neutra…
QCD Factorization and CP Asymmetries in Hadronic B Decays
Matthias Neubert
We review recent advances in the theory of strong-interaction effects and final-state interactions in hadronic weak decays of heavy mesons. In the heavy-quark limit, the amplitudes…
Applications of QCD Factorization in Hadronic B Decays
Matthias Neubert
We review recent advances in the theory of strong-interaction effects and final-state interactions in hadronic weak decays of heavy mesons. In the heavy-quark limit, the amplitudes…
Implications of a Low sin(2 beta): A Strategy for Exploring New Flavor Physics
Alexander L. Kagan, Matthias Neubert
We explore the would-be consequences of a low value of the CP-violating phase . The importance of a reference triangle obtained from measurements that are independent…
Towards a Theory of Hadronic B Decays
Matthias Neubert
We review recent advances in the theory of strong-interaction effects and final-state interactions in hadronic weak decays of heavy mesons. In the heavy-quark limit, the amplitudes…
QCD factorization for exclusive, non-leptonic B meson decays: General arguments and the case of heavy-light final states
M. Beneke, G. Buchalla, M. Neubert +1
We provide a rigorous basis for factorization for a large class of non-leptonic two-body -meson decays in the heavy-quark limit. The factorization formula incorporates elements…
On the Inclusive Determination of V_{ub} from the Lepton Invariant Mass Spectrum
Matthias Neubert
Bauer, Ligeti and Luke have recently proposed a new method for measuring |V_{ub}| in inclusive semileptonic B decays, using a cut on the lepton invariant mass to discriminate again…
Introduction to B Physics
Matthias Neubert
These lectures provide an introduction to various topics in heavy-flavor physics. We review the theory and phenomenology of heavy-quark symmetry, exclusive weak decays of meson…
Neutrino masses and mixings in non-factorizable geometry
Yuval Grossman, Matthias Neubert
We study bulk fermion fields in the localized gravity model with non-factorizable metric recently proposed by Randall and Sundrum, and Gogberashvili. In addition to a tower of weak…
