A Search for Leptoquarks at HERA

H1 Collaboration, S. Aid et al

A search for leptoquarks at HERA was performed in H1 using 1994 $e^{+} p$ data corresponding to an integrated luminosity of about $3 \pb^{-1}$. Single leptoquarks were searched for i…

Electromagnetic Corrections to the decays $η \to 3 π$

R. Baur, J. Kambor, D. Wyler

We calculate the electromagnetic corrections to the decays $η \to 3 π$ in next to leading order in the chiral expansion. We find that the corrections are small in accordance…

The Oscillating Universe: an Alternative to Inflation

Ruth Durrer, Joachim Laukenmann

The aim of this paper is to show, that the 'oscillating universe' is a viable alternative to inflation. We remind that this model provides a natural solution to the flatness or ent…

Final State Interactions and Khuri-Treiman Equations in $η \to 3 π$ decays

J. Kambor, C. Wiesendanger, D. Wyler

Using extended Khuri-Treiman equations, we evaluate the final state interactions due to two-pion rescatterings to the decays $η \to π^{0} π^{+} π^{-}$ and $η \to π^{0} π^{0} π^{0}$ . As subtracti…

A Note on Slavnov-Taylor Identities in the Causal Epstein-Glaser Approach

Tobias Hurth

An alternative approach to perturbative Yang-Mills theories in four (3+1) dimensional space-time based on the causal Epstein-Glaser method in QFT was recently proposed. In this sho…

Comparison of Deep Inelastic Scattering with Photoproduction Interactions at HERA

H1-Collaboration

Photon-proton ( $γ p$ ) interactions with~ $Q^{2} < 1 0^{- 2}$ ~GeV $^{2}$ and deep-inelastic scattering ( $γ^{*} p$ ) interactions with photon virtualities $Q^{2} > 5$ ~GeV $^{2}$ are studied at the high e…

Large Scale Structure Formation with Global Topological Defects. A new Formalism and its implementation by numerical simulations

R. Durrer, Z. -H. Zhou

We investigate cosmological structure formation seeded by topological defects which may form during a phase transition in the early universe. First we derive a partially new, local…

On the Corrections to Dashen's Theorem

Robert Baur, Res Urech

The electromagnetic corrections to the masses of the pseudoscalar mesons $π$ and $K$ are considered. We calculate in chiral perturbation theory the contributions which arise from r…

Specifying Logic Programs in Controlled Natural Language

Norbert E. Fuchs, Rolf Schwitter

Writing specifications for computer programs is not easy since one has to take into account the disparate conceptual worlds of the application domain and of software development. T…

Is $f_{0} (1500)$ a Scalar Glueball?

Claude Amsler, Frank Close

Following the discovery of two new scalar mesons, $f_{0} (1370)$ and $f_{0} (1500)$ at the Low Energy Antiproton Ring at CERN, we argue that the observed properties of this pair are inco…
