We review in this paper the first results obtained in an attempt at understanding quantum
space-time based on a new extension of the principle of relativity and on the geometrical …

This is the first detailed account of a new approach to microphysics based on two leading
ideas:(i) the explicit dependence of physical laws on scale encountered in quantum physics …

Electron-positron scattering provides a model-independent test for the existence of neutral
particles coupling to the e+ e-field. The authors review the effects of possible particle …

A comparison of meson masses with baryon excitation energies reveals a common mass-
band structure, in which particles with a variety of quantum numbers are grouped together …

Using a monochromatic e+ beam scattered on a Be foil and a high-resolution detector
device, the excitation function for elastic e+ e− scattering was measured with a statistical …

The recent search for new particles in the MeV mass range is reviewed. The most relevant
experiments, most notably the GSI positron experiments, are described and their results are …

We discuss the speculation that the sharp positron lines and correlated e+ e− and γγ signals
seen in heavy-ion collisions may be evidence for a new phase of QED. We examine several …

Electron-positron pairs apparently resulting from the decay of light intermediate neutral
particles emitted in relativistic heavy-ion collisions have been reported by El-Nadi and …

In this paper we present a variety of investigations inspired by the explanation of narrow e+
e− peaks in heavy-ion collisions as due to a possible new phase of QED. We extend, to the …

We have searched for narrow resonances in a fine energy scan of the Bhabha scattering
cross section. The statistical sensitivity was 1.6% for center-of-mass energies between 1.62 …
