In this formalism, the fermion binding energies are compensated by boson energies, indicating that particles can be generated out of the vacuum. This yields quantitative solutions for various mesons ¦Ø (0.78 GeV) - ¦´ (9.46 GeV) and all leptons e, ¦Ì and ¦Ó, with uncertainties in the extracted properties of less than 1¡ë. For transparency, a Web-page with the address htpps://h2909473.stratoserver.net has been constructed, where all calculations can be run on line and also the underlying fortran source code can be inspected. %K Quantum Field Theory of Fermion and Boson Fields %K Hadrons and Leptons Described as Bound States of Relativistic Fermions and Bosons %K Leading to a Total Energy Equal to Zero %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=131624
