Interest in particle physics continues apace. With the Large Hadron Collider showing
early tantalizing glimpses of what may yet prove to be the elusive Higgs Boson,
particle physics remains a fertile ground for creative theorists. While the Standard
model of particle physics remains hugely successful, nevertheless it is still not fully
regarded as a complete holistic description.
This Volume contains both the invited lectures and the contributions to the
Workshop on The Physics of Excited Nucleons (NSTAR 2001), which was
held at the Johannes Gutenberg-Universitat Mainz, March 7-10, 2001. The
origin of this workshop series goes back to the conference on Excited Baryons,
which was initiated and organized by our late friend Nimai Mukhopadhyay
and his colleagues at the Rensselaer Polytechnic Institute in 1988.
For many decades, scientists have been trying to devise a single unified theory to explain all known physical phenomena, but a model that appears to unite the seemingly incompatible String Theory and Standard Model has existed for 100 years. It described baryons, mesons, quarks and preons over 50 years before conventional science. It stated that matter is composed of strings 80 years before string theory. It described the existence of anti-matter 30 years before conventional science. It described the Higgs field over 50 years before Peter Higgs.
