Solitary waves and solitons are briefly discussed in their historical context, especially regarding the motivation to use solitons for particle models in the nonlinear Klein-Gordon (NKG) equation. Conservation equations for charge, energy, and momentum follow from Noether’s theorem in the usual way, …

Abstract A classical model is proposed in which two nonlinear Klein–Gordon fields interact via the electromagnetic field. Scaling is such that solitons in the two fields can be interpreted as electrons and protons, respectively. Even though the masses are very different, the …

Two-pion correlation functions are analyzed at midrapidity for three systems $(14.6A\mathrm{GeV}/c$ Si+Al, Si+Au, and $11.6A\mathrm{GeV}/c$ Au+Au), seven distinct centrality conditions, and different ${k}_{T}$ bins in the range 0.1--0.5 GeV/c. Source reference frames are determined from fits to the Yano-Koonin source parametrization. Bertsch-Pratt …

Proton and deuteron distributions from $11.6A \mathrm{GeV}/c$ Au + Au collisions measured by the E802 Collaboration in experiment E-866 are presented. The invariant yield of protons and deuterons is studied as a function of the transverse mass for different cuts of rapidity …

Charged kaon production has been measured in Si+Al and Si+Au collisions at $14.6A \mathrm{GeV}/c$, and Au+Au collisions at $11.1A \mathrm{GeV}/c$ by Experiments 859 and 866 (the E-802 Collaboration) at the BNL AGS. Invariant transverse mass spectra and rapidity distributions for both ${K}^{+}$ …

In this paper Au+Au collisions at $11.6A$ $\mathrm{GeV}/c$ are characterized by two global observables: the energy measured near zero degrees ${(E}_{\mathrm{ZCAL}})$ and the total event multiplicity. Particle spectra are measured for different event classes that are defined in a two-dimensional grid of …

A systematic study of the spectra and yields of ${K}^{+}$ and ${K}^{\ensuremath{-}}$ is reported by experiment E866 as a function of centrality in Au+Au collisions at $11.6A \mathrm{GeV}/c.$ The invariant transverse spectra for both kaon species are well described by exponentials in …

Antiproton production in $11.7A\mathrm{GeV}/c$ $\mathrm{Au}+\mathrm{Au}$ collisions over a wide transverse-mass coverage was studied using the AGS-E866 experimental apparatus. The mean transverse kinetic energy increases as a function of centrality and is similar to that of protons. The antiproton yields in $\mathrm{Si}+\mathrm{Al}$, $\mathrm{Si}+\mathrm{Au}$, …
