Possible detection of relic neutrinos and their mass
A. Ringwald
Recently the possibility was widely discussed that a large fraction of the highest energy cosmic rays may be decay products of Z bosons which were produced in the resonant annihila…
The Effective Fine Structure Constant at TESLA Energies
F. Jegerlehner
We present a new estimate of the hadronic contribution to the shift in the fine structure constant at LEP and TESLA energies and calculate the effective fine structure constant. Su…
Instanton Searches at HERA
A. Ringwald, F. Schrempp
The present status of our ongoing systematic study of the discovery potential of QCD-instanton induced events in deep-inelastic scattering at HERA is briefly reviewed. We emphasize…
Towards the Phenomenology of QCD-Instanton Induced Particle Production
A. Ringwald, F. Schrempp
We present a first status report on a broad and systematic study of possible manifestations of QCD-instantons at HERA. Considerable motivation comes from the close analogy between…
