Inclusive Decays of B Mesons into D_s and at Including Polarization Effects

M. Fischer, S. Groote, J. G. Körner +1

The dominant contribution to the inclusive decays of mesons into the charm-strangeness mesons and is expected to be given by the partonic process $b \to c+(D…

corrections to the correlator of finite mass baryon currents

S. Groote, J. G. Körner, A. A. Pivovarov

We present analytical next-to-leading order results for the correlator of baryonic currents at the three loop level with one finite mass quark. We obtain the massless and the HQET…

Cosmological Expansion in the Randall-Sundrum Brane World Scenario

Eanna E. Flanagan, S. -H. Henry Tye, Ira Wasserman

The cosmology of the Randall-Sundrum scenario for a positive tension brane in a 5-D Universe with localized gravity has been studied previously. In the radiation-dominated Universe…

Determination of the weak phase gamma=arg(V_ub^*)

Matthias Neubert

Various strategies for extracting or constraining the weak phase gamma with controlled theoretical uncertainties are reviewed. Measurements of the rates for the hadronic decays B^+…

Model-independent information on gamma from B^+- -> pi K Decays

Matthias Neubert

Measurements of the rates for the hadronic decays B^+- -> pi K can be used to derive information on the weak phase gamma=arg(V_ub^*) in a largely model-independent way. Hadronic un…

A Cosmology of the Brane World

Eanna E. Flanagan, S. -H. Henry Tye, Ira Wasserman

We develop a possible cosmology for a Universe with n additional spatial dimensions of variable scale, and an associated scalar field, the radion, which is distinct from the field…

Rescattering and electroweak penguin effects in determinations of the weak phase

Dan Pirjol

Determinations of the CKM phase from weak nonleptonic decays are affected by electroweak (EW) penguins and rescattering effects. In this talk it is explained how the EW pen…

Measurement of CP Violation at the without Time Ordering or

A. Foland

I derive the expressions for the CP-violating asymmetry arising from interference between mixed and direct decays in the Upsilon(4S) system, for the case in which only one of the B…

Collider Signatures from the Brane World

Gary Shiu, Robert Shrock, S. -H. Henry Tye

We discuss some collider signatures of the brane world. In addition to the usual bulk (closed string) fields and brane (open string) fields in the Type I string picture, there are…

Local and global duality and the determination of α(M_Z)

S. Groote

This talk presents work concepts and results for the determination of the fine structure constant at the mass resonance. The problem consisting of the break-down of globa…

Transcendental numbers and the topology of three-loop bubbles

S. Groote, J. G. Körner, A. A. Pivovarov

We present a proof that all transcendental numbers that are needed for the calculation of the master integrals for three-loop vacuum Feynman diagrams can be obtained by calculating…

Bounding the penguin effects on determinations of from decays

Dan Pirjol

In the absence of the QCD penguin contributions a measurement of the time-dependent asymmetry in the decay gives directly the weak angle . Several bounds have…
