Strongly interacting neutrinos as the highest energy cosmic rays
Z. Fodor, S. D. Katz, A. Ringwald +1
We show that all features of the ultrahigh energy cosmic ray spectrum from 10^{17} eV to 10^{21} eV can be described with a simple power-like injection spectrum of protons under th…
Bounds on the cosmogenic neutrino flux
Z. Fodor, S. D. Katz, A. Ringwald +1
Under the assumption that some part of the observed highest energy cosmic rays consists of protons originating from cosmological distances, we derive bounds on the associated flux…
An upper bound on the total cross-section for electroweak baryon number violation
A. Ringwald
An upper bound on the total cross-section of s-wave electroweak instanton/sphaleron induced baryon plus lepton number violating processes is presented. It is obtained by exploiting…
Production and detection of very light bosons in the HERA tunnel
A. Ringwald
There are strong theoretical arguments in favour of the existence of very light scalar or pseudoscalar particles beyond the Standard Model which have, so far, remained undetected,…
Boiling the Vacuum with an X-Ray Free Electron Laser
A. Ringwald
X-ray free electron lasers will be constructed in this decade, both at SLAC in the form of the so-called Linac Coherent Light Source as well as at DESY, where the so-called TESLA X…
Electroweak instantons as a solution to the ultrahigh energy cosmic ray puzzle
Z. Fodor, S. D. Katz, A. Ringwald +1
We propose a scenario in which a simple power-like primary spectrum for protons with sources at cosmological distances leads to a quantitative description of all the details of the…
