On the Mass of the Dark Compact Halo Objects
Philippe Jetzer, Eduard Masso
Recently the French EROS collaboration and the American-Australian MACHO collaboration have reported the observation of altogether three possible microlensing events by monitoring…
Einstein-Yang-Mills sphalerons and fermion number non-conservation
Mikhail S. Volkov
It is argued that the sphaleron solutions appearing in the Einstein-Yang-Mills theory are important in the transition processes at extremely high energies. Namely, when the energy…
Unstable particles in One Loop Calculations
Andre Aeppli, Geert Jan van Oldenborgh, Daniel Wyler
We present a gauge invariant way to compute one loop corrections to processes involving the production and decay of unstable particles.
Gauge Invariant Cosmological Perturbation Theory
Ruth Durrer
After an introduction to the problem of cosmological structure formation, we develop gauge invariant cosmological perturbation theory. We derive the first order perturbation equati…
Microwave Anisotropies from Texture Seeded Structure Formation
R. Durrer, A. Howard, Z. -H. Zhou
The cosmic microwave anisotropies in a scenario of large scale structure formation with cold dark matter and texture are discussed and compared with recent observational results of…
Early Reionization in Cosmology
Ruth Durrer
The cosmic microwave background (CMB) anisotropies have turned out to represent one of the most stringent 'bottle necks' for scenarios of large scale structure formation. As a poss…
Selfgravitating Yang-Mills solitons and their Chern-Simons numbers
O. Brodbeck, N. Straumann
We present a classification of the possible regular, spherically symmetric solutions of the Einstein-Yang-Mills system which is based on a bundle theoretical analysis for arbitrary…
Quantum cosmology and the emergence of a classical world
C. Kiefer
This paper gives an elementary introduction to some of the conceptual problems of quantum cosmology. Contents: 1. Why quantum cosmology? 2. Time in quantum gravity 3.Decoherence an…
Constraints on the Higss and Top Quark Masses From Effective Potential and Non-Commutative Geometry
A. H. Chamseddine, J. Fröhlich
We consider the standard model in the formulationo of non-commutative geometry, for a Euclidean space-time consisting of two copies. The electroweak scale is set by the vacuum expe…
Renormalization Group Equations for Seesaw Neutrino Masses
Piotr H. Chankowski, Zbigniew Pluciennik
RGEs for coefficients of dim-5 operators giving rise to neutrino masses in the seesaw mechanism are written down in the SM, 2HDM and MSSM, and solved numerically. RG evolution of t…
On time and the quantum-to-classical transition in Jordan-Brans-Dicke quantum gravity
Claus Kiefer, Erik A. Martinez
Any quantum theory of gravity which treats the gravitational constant as a dynamical variable has to address the issue of superpositions of states corresponding to different eigenv…
Topology, Decoherence, and Semiclassical Gravity
C. Kiefer
We address the issue of recovering the time-dependent Schrödinger equation from quantum gravity in a natural way. To reach this aim it is necessary to understand the nonoccurrence…
Charged Boson Stars and Vacuum Instabilities
P. Jetzer, P. Liljenberg, B. -S. Skagerstam
We consider charged boson stars and study their effect on the structure of the vacuum. For very compact particle like ``stars", with constituent mass close to the Planck ma…
SO(10) Unification in Non-Commutative Geometry
A. H. Chamseddine, J. Fr/''ohlich
We construct an grand unified theory in the formulation of non-com-\break mutative geometry. The geometry of space-time is that of a product of a continuos four dimensiona…
Cycles and Circles in Roundoff Errors
George G. Szpiro
When a series of measurements is performed with increasingly coarse (or increasingly fine) precision, consecutive observations seem to be erratically distributed at first, and then…
