Rotating Black Holes/Rings at Future Colliders
Daisuke Ida, Kin-ya Oda, Seong Chan Park
The hierarchy between the electroweak and Planck scales can be reduced when the extra dimensions are compactified with large volume or with warped geometry, resulting in the fundam…
B_s-B_s-bar mixing in an SO(10) SUSY GUT model
Sebastian Jager, Ulrich Nierste
We perform a renormalisation group analysis of the SO(10) model proposed by Chang, Masiero and Murayama, which links the large atmospheric neutrino mixing angle to loop-induced tra…
Structure of the Nucleon
M. Göckeler, T. R. Hemmert, R. Horsley +5
Generalized parton distributions provide information on the longitudinal and transverse distribution of partons in the fast moving nucleon. Furthermore, they contain information on…
B -> pi pi, New Physics in B -> pi K and Implications for Rare K and B Decays
Andrzej J. Buras, Robert Fleischer, Stefan Recksiegel +1
The measured B -> pi pi, pi K branching ratios exhibit puzzling patterns. We point out that the B -> pi pi hierarchy can be nicely accommodated in the Standard Model (SM) through n…
Complete NNLO QCD Analysis of B -> X_s l^+ l^- and Higher Order Electroweak Effects
Christoph Bobeth, Paolo Gambino, Martin Gorbahn +1
We complete the next-to-next-to-leading order QCD calculation of the branching ratio for B -> X_s l^+ l^- including recent results for the three-loop anomalous dimension matrix and…
Chiral Perturbation Theory in a Nuclear Background
L. Girlanda, A. Rusetsky, W. Weise
We propose a novel way to formulate Chiral Perturbation Theory in a nuclear background, characterized by a static, non-uniform distribution of the baryon number that describes the…
The Top--Down Interpretation of Ultra--High Energy Cosmic Rays
Manuel Drees
The origin of Ultra--High Energy ($E \gsim 10^{20}$ eV) Cosmic Rays (UHECR) remains mysterious. I discuss ``top--down'' models, where UHECR originate from the decay of very massive…
Analysis of CP Violation in Neutralino Decays to Tau Sleptons
S. Y. Choi, M. Drees, B. Gaissmaier +1
In the minimal supersymmetric standard model, tau sleptons and neutralinos are expected to be among the lightest supersymmetric particles that c…
Quasiparticle Description of Hot QCD at Finite Quark Chemical Potential
M. A. Thaler, R. A. Schneider, W. Weise
We study the extension of a phenomenologically successful quasiparticle model that describes lattice results of the equation of state of the deconfined phase of QCD for Tc <= T < 4…
Two-photon decays of pi^0, eta and eta-prime
B. Borasoy, R. Nissler
We investigate the decays of pi^0, eta and eta-prime into two photons in an effective U(3) chiral Lagrangian approach without employing large N_c arguments. Tree level and one-loop…
Minimal Flavour Violation
Andrzej J. Buras
These lectures give a description of models with minimal flavour violation (MFV) that can be tested in and meson decays. This class of models can be formulated to a very go…
Why a long-lived fireball can be compatible with HBT measurements
Thorsten Renk
The common interpretation of HBT data measured at top SPS energies leads to apparent source lifetimes of 6-8 fm/c and emission duration of approximately 2-3 fm/c. We investigate a…
Understanding CP phase-dependent measurements at neutrino superbeams in terms of bi-rate graphs
Walter Winter
We discuss the impact of the true value of the CP phase on the mass hierarchy, CP violation, and CP precision measurements at neutrino superbeams and related experiments. We we use…
More Model-Independent Analysis of b->s Processes
G. Hiller, F. Krüger
We study model-independently the implications of non-standard scalar and pseudoscalar interactions for the decays b ->s gamma, b -> s g, b -> s l^+l^- (l=e,mu) and B_s -> mu^+ mu^-…
The Higgs Penguin and its Applications : An overview
Athanasios Dedes
We review the effective Lagrangian of the Higgs penguin in the Standard Model and its minimal supersymmetric extension (MSSM). As a master application of the Higgs penguin, we disc…
Status of three-neutrino oscillations after the SNO-salt data
M. Maltoni, T. Schwetz, M. A. Tortola +1
We perform a global analysis of neutrino oscillation data in the framework of three neutrinos, including the recent improved measurement of the neutral current events at SNO. In ad…
The B -> pi K Puzzle and its Relation to Rare B and K Decays
Andrzej J. Buras, Robert Fleischer, Stefan Recksiegel +1
The Standard-Model interpretation of the ratios of charged and neutral B-> pi K rates, R_c and R_n, respectively, points towards a puzzling picture. Since these observables are aff…
Resolving degeneracies for different values of
Walter Winter
We discuss options to resolve correlations and degeneracies with combinations of future neutrino long-baseline experiments. We use a logarithmic scale of as a rep…
The role of matter density uncertainties in the analysis of future neutrino factory experiments
Tommy Ohlsson, Walter Winter
Matter density uncertainties can affect the measurements of the neutrino oscillation parameters at future neutrino factory experiments, such as the measurements of the mixing param…
Variations on KamLAND: likelihood analysis and frequentist confidence regions
Thomas Schwetz
In this letter the robustness of the first results from the KamLAND reactor neutrino experiment with respect to variations in the statistical analysis is considered. It is shown th…
The Impact of Universal Extra Dimensions on FCNC Processes
Andrzej J. Buras, Anton Poschenrieder, Michael Spranger +1
We review the results of two papers on FCNC processes in the Appelquist, Cheng and Dobrescu (ACD) model with one universal extra dimension.
Cutoff schemes in chiral perturbation theory and the quark mass expansion of the nucleon mass
Véronique Bernard, Thomas R. Hemmert, Ulf-G. Meißner
We discuss the use of cutoff methods in chiral perturbation theory. We develop a cutoff scheme based on the operator structure of the effective field theory that allows to suppress…
