Symmetry Breaking and Time Variation of the QCD Coupling
H. Fritzsch
Astrophysical indications that the fine structure constant has undergone a small time variation during the cosmological evolution are discussed within the framework of the standard…
Consequences of kinetic non-equilibrium for the nuclear equation-of-state in heavy ion collision
C. Fuchs, T. Gaitanos
Highly compressed nuclear matter created in relativistic heavy collisions is to large extent governed by local non-equilibrium. As an idealized scenario colliding nuclear matter co…
Decoherence and gate performance of coupled solid state qubits
Markus J. Storcz, Frank K. Wilhelm
Solid state quantum bits are promising candidates for the realization of a {\em scalable} quantum computer. However, they are usually strongly limited by decoherence due to the man…
Four-Zero Texture of Hermitian Quark Mass Matrices and Current Experimental Tests
Harald Fritzsch, Zhi-zhong Xing
We show that the four-zero texture of Hermitian quark mass matrices can survive current experimental tests: it is able to yield sufficiently large predictions for the flavor mixing…
Variational charge renormalization in charged systems
Roland R. Netz, Henri Orland
We apply general variational techniques to the problem of the counterion distribution around highly charged objects where strong condensation of counterions takes place. Within a f…
Fermi 1D quantum gas: Luttinger liquid approach and spin-charge separation
A. Recati, P. O. Fedichev, W. Zwerger +1
We discuss the properties of quasi-1D quantum gases of fermionic atoms using the Luttinger liquid theory, including the presence of an optical lattice and of a longitudinal trappin…
Non-LTE Abundances of Magnesium, Aluminum and Sulfur in OB Stars Near the Solar Circle
S. Daflon, K. Cunha, V. V. Smith +1
Non-LTE abundances of magnesium, aluminum and sulfur are derived for a sample of 23 low-v \sin i stars belonging to six northern OB associations of the Galactic disk within 1 kpc o…
Two-Loop Results for M_W in the Standard Model and the MSSM
Ayres Freitas, Sven Heinemeyer, Georg Weiglein
Recent higher-order results for the prediction of the W-boson mass, M_W, within the Standard Model are reviewed and an estimate of the remaining theoretical uncertainties of the el…
The Higgs Boson Masses of the Complex MSSM: A Complete One-Loop Calculation
M. Frank, S. Heinemeyer, W. Hollik +1
In the Minimal Supersymmetric Standard Model with complex parameters (cMSSM) we perform a complete one-loop calculation for the Higgs boson masses (including the momentum dependenc…
Relativistic effects in the search for high density symmetry energy
V. Greco, V. Baran, M. Colonna +3
Intermediate energy heavy ion collisions open the unique possibility to explore the Equation of State () of nuclear matter far from saturation, in particular the density depen…
The photon-neutrino interaction in non-commutative gauge field theory and astrophysical bounds
Peter Schupp, Josip Trampetic, Julius Wess +1
In this letter we propose a possible mechanism of left- and right-handed neutrino couplings to photons, which arises quite naturally in non-commutative gauge field theory. We estim…
Towards High-Precision Predictions for the MSSM Higgs Sector
G. Degrassi, S. Heinemeyer, W. Hollik +2
The status of the evaluation of the MSSM Higgs sector is reviewed. The phenomenological impact of recently obtained corrections is discussed. In particular it is shown that the upp…
Measurement of single-spin azimuthal asymmetries in semi-inclusive electroproduction of pions and kaons on a longitudinally polarised deuterium target
HERMES collaboration, A. Airapetian
Single-spin asymmetries have been measured for semi-inclusive electroproduction of , , and mesons in deep-inelastic scattering off a longitudinally polarised…
Nonlinear cotunneling through an artificial molecule
Udo Hartmann, Frank K. Wilhelm
We study electron transport through a system of two lateral quantum dots coupled in series. We consider the case of weak coupling to the leads and a bias point in the Coulomb block…
Probing the Friedmann equation during recombination with future CMB experiments
Oliver Zahn, Matias Zaldarriaga
We show that by combining measurements of the temperature and polarization anisotropies of the Cosmic Microwave Background (CMB), future experiments will tightly constrain the expa…
Regional averaging and scaling in relativistic cosmology
Thomas Buchert, Mauro Carfora
Averaged inhomogeneous cosmologies lie at the forefront of interest, since cosmological parameters like the rate of expansion or the mass density are to be considered as volume-ave…
Status of Electroweak Corrections to Top Pair Production
J. Fleischer, A. Leike, T. Riemann +1
We review the status of electroweak radiative corrections to top-pair production at a Linear Collider well above the production threshold. We describe the Fortran package topfit an…
A Measurement of the tau -> mu nu nu Branching Ratio
The OPAL collaboration, G. Abbiendi
The tau -> mu nu nu branching ratio has been measured using data collected from 1990 to 1995 by the OPAL detector at the LEP collider. The resulting value of B(tau -> mu nu nu) = 0…
Very Heavy MSSM Higgs-Boson Production at the Linear Collider
T. Hahn, S. Heinemeyer, G. Weiglein
In the Minimal Supersymmetric Standard Model (MSSM) we present the corrections to the heavy neutral CP-even Higgs-boson production in the WW-fusion and Higgs-strahlung channel, e+e…
Radiative Corrections to Radiative B Decays: Exclusive B -> V gamma at NLO
Gerhard Buchalla
We discuss a model-independent framework for the analysis of the radiative B-meson decays B -> K* gamma and B -> rho gamma based on the heavy-quark limit of QCD. We present a facto…
Precision Analysis of the Lightest MSSM Higgs Boson at Future Colliders
John Ellis, Sven Heinemeyer, Keith A. Olive +1
We investigate the sensitivity of observables measurable in e^+ e^-, gamma gamma and mu^+ mu^- collisions for distinguishing the properties of the light neutral CP-even Higgs boson…
A stellar relic from the early Milky Way
Norbert Christlieb, Michael S. Bessell, Timothy C. Beers +6
The chemical composition of the most metal-deficient stars reflects the composition of the gas from which they formed. These old stars provide crucial clues to the star formation h…
Symplectic homology and periodic orbits near symplectic submanifolds
Kai Cieliebak, Viktor L. Ginzburg, Ely Kerman
We show that a small neighborhood of a closed symplectic submanifold in a geometrically bounded aspherical symplectic manifold has non-vanishing symplectic homology. As a consequen…
Kondo excitons in self-assembled quantum dots
A. O. Govorov, K. Karrai, R. J. Warburton
We describe novel excitons in quantum dots by allowing for an interaction with a Fermi sea of electrons. We argue that these excitons can be realized very simply with self-assemble…
