Radiative B Decays: Standard Candles of Flavor Physics
Matthias Neubert
Rare radiative decays based on b->s+gamma transitions are among the most prominent examples of flavor-changing neutral current processes. They benefit from good theoretical control…
Revised term of lepton from the Feynman diagrams containing an internal light-by-light scattering subdiagram
T. Kinoshita, M. Nio
The contribution to the lepton from a gauge-invariant set of 18 Feynman diagrams containing a light-by-light scattering subdiagram internally has been reevaluated by a…
Big Corrections from a Little Higgs
C. Csaki, J. Hubisz, G. D. Kribs +2
We calculate the tree-level expressions for the electroweak precision observables in the SU(5)/SO(5) littlest Higgs model. The source for these corrections are the exchange of heav…
Spectator Interactions in Soft-Collinear Effective Theory
Richard J. Hill, Matthias Neubert
Soft-collinear effective theory is generalized to include soft massless quarks in addition to collinear fields. This extension is necessary for the treatment of interactions with t…
Flavor-Singlet B-Decay Amplitudes in QCD Factorization
Martin Beneke, Matthias Neubert
Exclusive hadronic B-meson decays into two-body final states consisting of a light pseudoscalar or vector meson along with an eta or eta' meson are of great phenomenological intere…
Standard Model Higgs from Higher Dimensional Gauge Fields
Csaba Csaki, Christophe Grojean, Hitoshi Murayama
We consider the possibility that the standard model Higgs fields may originate from extra components of higher dimensional gauge fields. Theories of this type considered before hav…
Pade/renormalization-group improvement of inclusive semileptonic B decay rates
M. R. Ahmady, F. A. Chishtie, V. Elias +4
Renormalization Group (RG) and optimized Pade-approximant methods are used to estimate the three-loop perturbative contributions to the inclusive semileptonic b \to u and b \to c d…
Renormalization-Mass Scale Dependence in QCD Contributions to Semileptonic Decay
M. R. Ahmady, F. A. Chishtie, V. Elias +4
QCD contributions to the decay rate, which are known to two-loop order in the scheme, exhibit sufficient dependence on the renormalization ma…
Subleading Shape Functions and the Determination of |V_{ub}|
Matthias Neubert
It is argued that the dominant subleading shape-function contributions to the endpoint region of the charged-lepton energy spectrum in B -> X_u l nu decays can be related in a mode…
Optimal Renormalization-Group Improvement of the Perturbative Series for the e^+ e^- -Annihilation Cross-Section
M. R. Ahmady, F. A. Chishtie, V. Elias +5
Using renormalization-group methods, we derive differential equations for the all-orders summation of logarithmic corrections to the QCD series for R(s) = sigma(e^+ e^- --> hadrons…
Moriond QCD 2002: Theoretical Summary
Matthias Neubert
I summarize highlights of the theory talks presented at the 37th Rencontres de Moriond on QCD and High Energy Hadronic Interactions.
Two-body modes of B mesons and the CP-b triangle
Matthias Neubert
The study of charmless two-body decays of B mesons is currently one of the hottest topics in B physics. QCD factorization provides the theoretical framework for a systematic analys…
Constraints on the SU(3) Electroweak Model
Csaba Csaki, Joshua Erlich, Graham D. Kribs +1
We consider a recent proposal by Dimopoulos and Kaplan to embed the electroweak SU(2)_L X U(1)_Y into a larger group SU(3)_W X SU(2) X U(1) at a scale above a TeV. This idea is mot…
Higher-Order Corrections to QCD Factorization in B->pi K,pi pi Decays
Matthias Neubert, Ben D. Pecjak
The renormalon calculus is used to calculate the terms of order in the perturbative expansions of the Wilson coefficients and hard-scattering kernels entering the…
Closed-Form Summation of RG-Accessible Logarithmic Contributions to Semileptonic B-Decays and Other Perturbative Processes
M. R. Ahmady, F. A. Chishtie, V. Elias +5
For any perturbative series that is known to -subleading orders of perturbation theory, we utilise the process-appropriate renormalization-group (RG) equation in order to obtain…
The Effective Lagrangian in the Randall-Sundrum Model and Electroweak Physics
Csaba Csaki, Joshua Erlich, John Terning
We consider the two-brane Randall-Sundrum (RS) model with bulk gauge fields. We carefully match the bulk theory to a 4D low-energy effective Lagrangian. In addition to the four-fer…
