On the Cohomology of the Noncritical -string
E. Bergshoeff, J. de Boer, M. de Roo +1
We investigate the cohomology structure of a general noncritical -string. We do this by introducing a new basis in the Hilbert space in which the BRST operator splits into a `…
Top Condensation without Fine-Tuning
Andreas Blumhofer
Quadratic divergencies which lead to the usual fine-tuning or hierarchy problem are discussed in top condensation models. As in the Standard Model a cancellation of quadratic diver…
Operator Formalism on the Symmetric Algebraic Curves
F. Ferrari, J. Sobczyk, W. Urbanik
In this work, the following conjectures are proven in the case of a Riemann surface with abelian group of symmetry: a) The systems on a Riemann surface are equivalent to…
On the Schwinger Model on Riemann Surfaces
Franco Ferrari
In this paper, the massless Schwinger model or two dimensional quantum electrodynamics is exactly solved on a Riemann surface. The partition function and the generating functional…
Hadron Multiplicities in the Presence of Light Gluinos
Frank Cuypers
We consider the effect of a massless gluino on the evolution of a parton shower. The hadron multiplicity distribution is predicted to evolve as a function of the collider energy in…
Universal bundle for gravity, local index theorem, and covariant gravitational anomalies
Gerald Kelnhofer
Consistent and covariant Lorentz and diffeomorphism anomalies are investigated in terms of the geometry of the universal bundle for gravity. This bundle is explicitly constructed a…
Mirror Symmetry, Mirror Map and Applications to Calabi-Yau Hypersurfaces
S. Hosono, A. Klemm, S. Theisen +1
Mirror Symmetry, Picard-Fuchs equations and instanton corrected Yukawa couplings are discussed within the framework of toric geometry. It allows to establish mirror symmetry of Cal…
Global existence of classical solutions to the Vlasov-Poisson system in a three dimensional, cosmological setting
Gerhard Rein, Alan D. Rendall
The initial value problem for the Vlasov-Poisson system is by now well understood in the case of an isolated system where, by definition, the distribution function of the particles…
A regularity theorem for solutions of the spherically symmetric Vlasov-Einstein system
Gerhard Rein, Alan D. Rendall, Jack Schaeffer
In a previous paper two of the authors (G. R. and A. D. R.) showed that there exist global, classical solutions of the spherically symmetric Vlasov-Einstein system for small initia…
QCD Calculation of the Form Factors
V. M. Belyaev, A. Khodjamirian, R. Rückl
We calculate the form factors for the heavy-to-light transitions by means of QCD sum rules using and light-cone wave functions. Higher twist contributio…
Supersymmetric Signals in Collisions
Frank Cuypers, Geert Jan van Oldenborgh, Reinhold Rückl
We consider the production and decay of selectrons and charginos in collisions. The advantage over usual collisions is the very low level of standard model backgr…
Static solutions of the spherically symmetric Vlasov-Einstein system
Gerhard Rein
The Vlasov-Einstein system describes the evolution of an ensemble of particles (such as stars in a galaxy, galaxies in a galaxy cluster etc.) interacting only by the gravitational…
Classical and super W-algebras from a zero-curvature condition
Francois Gieres, Stefan Theisen
Starting from superdifferential operators in an superfield formulation, we present a systematic prescription for the derivation of classical and super W-algebras…
Mirror Maps and Instanton Sums for Complete Intersections in Weighted Projective Space
A. Klemm, S. Theisen
We consider a class of Calabi-Yau compactifications which are constructed as a complete intersection in weighted projective space. For manifolds with one Kähler modulus we construc…
On the Quantization of the Chern-Simons Fields Theory on Curved Space-Times: the Coulomb Gauge Approach
Franco Ferrari
We consider here the Chern-Simons field theory with gauge group SU(N) in the presence of a gravitational background that describes a two-dimensional expanding ``universe". Two spec…
$\order(Γ)$ Corrections to pair production in and collisions
Andre Aeppli, Frank Cuypers, Geert Jan van Oldenborgh
Several schemes to introduce finite width effects to reactions involving unstable elementary particles are given and the differences between them are investigated. The effects of t…
Supersymmetric Signals in Collisions
Frank Cuypers, Geert Jan van Oldenborgh, Reinhold Rückl
We study the occurrence of final states with only an electron-positron pair and missing transverse momentum as a signal of \susy\ in photon-photon collisions. Suitable high energy…
On the Geometrical Structure of Covariant Anomalies in Yang-Mills Theory
Gerald Kelnhofer
Covariant anomalies are studied in terms of the theory of secondary characteristic classes of the universal bundle of Yang-Mills theory. A new set of descent equations is derived w…
Planck-Scale Physics and Solutions to the Strong CP Problem without Axion
Z. G. Berezhiani, R. N. Mohapatra, G. Senjanovic
We analyse the impact of quantum gravity on the possible solutions to the strong CP problem which utilize the spontaneously broken discrete symmetries, such as parity and time reve…
