CP violation in decays of the lightest supersymmetric particle with bilinearly broken R parity
M. Hirsch, T. Kernreiter, W. Porod
Supersymmetric models with broken R-parity induced by lepton number violating terms provide a calculable framework for neutrino masses and mixings. Within models with bilinear R-pa…
The Quantum Supersymmetric Vector Multiplet and Some Problems in Non-Abelian Supergauge Theory
Dan Radu Grigore, Günter Scharf
We consider the supersymmetric vector multiplet in a purely quantum framework. We obtain some discrepancies with respect to the literature in the expression of the super-propagator…
Products of hyperbolic metric spaces II
Thomas Foertsch, Viktor Schroeder
In arXiv math.MG/0207296 we introduced a product construction for locally compact, complete, geodesic hyperbolic metric spaces. In the present paper we define the hyperbolic produc…
Consistent treatment of spin-1 mesons in the light-front formalism
Wolfgang Jaus
We analyze the matrix element of the electroweak current between $q \qb$ vector meson states in the framework of a covariant extension of the light-front formalism. The light-front…
Extraction of cluster parameters with future Sunyaev-Zel'dovich observations
Nabila Aghanim, Steen H. Hansen, Sergio Pastor +1
The Sunyaev-Zel'dovich (SZ) effect of galaxy clusters is characterized by three parameters: Compton parameter, electron temperature and cluster peculiar velocity. In the present st…
J-ψProduction via χ_c Decays in 920 GeV pA Interactions
B Collaboration
Using data collected by the HERA-B experiment, we have measured the fraction of Jψ's produced via radiative chi_c decays in interactions of 920 GeV protons with carbon and titanium…
Possible flakes of molecular hydrogen in the early Universe
D. Pfenniger, D. Puy
The thermochemistry of H2 and HD in non-collapsed, non-reionized primordial gas up to the end of the dark age is investigated with recent radiation-matter and chemical reaction rat…
Aspherical galaxy clusters: effects on cluster masses and gas mass fractions
Rocco Piffaretti, Philippe Jetzer, Sabine Schindler
We present an investigation of the effects of asphericity on the estimates of total mass and gas mass fraction in galaxy clusters from X-ray observations. We model the aspherical s…
Anisotropy of the superconducting state properties and phase diagram of MgB2 by torque magnetometry on single crystals
M. Angst, R. Puzniak, A. Wisniewski +6
The angular and temperature dependence of the upper critical field Hc2 in MgB2 was determined from torque magnetometry measurements on single crystals. The Hc2 anisotropy gamma_H w…
Relationship between the isotope effects on transition temperature, specific heat and penetration depths
T. Schneider
We show that in anisotropic superconductors, falling at finite temperature into the 3D-XY- and at zero temperature into the 2D-XY-QSI universality class, the isotope effects on tra…
Universal properties of cuprate superconductors
T. Schneider
To provide an understanding of the universal properties emerging from the empirical correlations and phase diagrams of cuprate superconductors, we invoke the scaling theory of fini…
Wilson surfaces and higher dimensional knot invariants
Alberto S. Cattaneo, Carlo A. Rossi
An observable for nonabelian, higher-dimensional forms is introduced, its properties are discussed and its expectation value in BF theory is described. This is shown to produce pot…
New physics searches at a Linear Collider with polarized beams
G. Moortgat--Pick, A. Bartl, K. Hidaka +7
A future e+e- Linear Collider has a large physics potential for the discovery of new physics beyond the Standard Model and precision studies of the Standard Model itself. It is wel…
The Reconstruction of Supersymmetric Theories at High Energy Scales
G. A. Blair, W. Porod, P. M. Zerwas
The reconstruction of fundamental parameters in supersymmetric theories requires the evolution to high scales, where the characteristic regularities in mechanisms of supersymmetry…
Factorization in leptonic radiative B -> gamma eνdecays
Enrico Lunghi, Dan Pirjol, Daniel Wyler
We discuss factorization in exclusive radiative leptonic B->γeνdecays using the soft-collinear effective theory. The form factors describing these decays can be expanded in a power…
Associated primes of graded components of local cohomology modules
Markus P. Brodmann, Mordechai Katzman, Rodney Y. Sharp
The -th local cohomology module of a finitely generated graded module over a standard positively graded commutative Noetherian ring , with respect to the irrelevant ideal…
Microlensing of strongly interacting binary systems
V. Bozza, L. Mancini
Many binary systems are in a state of strong interaction, where mass exchanges, accretion disks, common envelopes provide circumstellar matter which can have significant effects in…
B0 -> D*- a1+: Chirality tests and resolving an ambiguity in 2β+γ
Michael Gronau, Dan Pirjol, Daniel Wyler
We point out that the decays of B mesons into a vector meson and an axial-vector meson can distinguish between left and right-handed polarized mesons, in contrast to decays into tw…
The influence of magnetic fields on the Sunyaev Zel'dovich effect in clusters of galaxies
P. M. Koch, Ph. Jetzer, D. Puy
We study the influence of intracluster large scale magnetic fields on the thermal Sunyaev-Zel'dovich (SZ) effect. In a macroscopic approach we complete the hydrostatic equilibrium…
Cooling flow bulk motion corrections to the Sunyaev Zel'dovich effect
P. M. Koch, Ph. Jetzer, D. Puy
We study the influence of converging cooling flow bulk motions on the Sunyaev-Zel'dovich (SZ) effect. To that purpose we derive a modified Kompaneets equation which takes into acco…
Strebel differentials on stable curves and Kontsevich's proof of Witten's conjecture
Dimitri Zvonkine
We define Strebel differentials for stable complex curves, prove the existence and uniqueness theorem that generalizes Strebel's theorem for smooth curves, prove that Strebel diffe…
Hyperbolic Rank of Products
Thomas Foertsch, Viktor Schroeder
Generalizing results due to Brady and Farb we prove the existence of a bilipschitz embedded manifold of pinched negative curvature and dimension m_1+m_2-1 in the product X:=X_1^{m_…
Non Standard Metric Products
Andreas Bernig, Thomas Foertsch, Viktor Schroeder
We consider a fairly general class of natural non standard metric products and classify those amongst them, which yield a product of certain type (for instance an inner metric spac…
The history of the cosmological constant problem
Norbert Straumann
The interesting early history of the cosmological term is reviewed, beginning with its introduction by Einstein in 1917 and ending with two papers of Zel'dovich, shortly before the…
