The progress of science is much more muddled than is depicted in most history books. This is especially true of theoretical physics, partly because history is written by the victorious. Consequently, historians of science often ignore the many alternate paths that people wandered down, the many false clues they followed, the many misconceptions they had. These alternate points of view are less ...

Unless flavour symmetries are assumed, particle masses and mixings are generally undetermined in gauge theories. Understanding mass and mixing constitutes one of the biggest challenges in elementary particle physics. Current observations do not determine all elements of the effective neutrino mass matrix Mν completely and this will be a great challenge even for future experiments. Therefore the...

The Standard Model of elementary particles can not be the final theory. There are theoretical reasons to expect the appearance of new physics, possibly at the energy scale of few TeV. Several possible theories of new physics have been proposed, each with unknown probability to be confirmed. Instead of arbitrarily choosing to examine one of those theories, this thesis is about searching for any ...

A novel gauge model which has a spontaneously broken parity symmetry is constructed. The model has only 2 parameters beyond those of the standard model. Some of the unusual implications of the model are discussed. 1 Email: [email protected] The standard model of particle physics (SM) is an extremely successful description of past and existing experiments. At present there is no experim...

~ 'HE formalism of mesotron field theories was first developed in analogy either with the method of classical electrodynamics that involves the determination of fields produced by pregiven sources, or with the perturbation technique of quantum electrodynamics. This program not only has led to predictions in contradiction with experiment (the singular nature of nuclear forces, and large cross se...

THE URGE TO REDUCE THE FORMS of matter to a few elementary constituents must be very ancient. By 450 BCE, Empedocles had already developed or inherited a “standard model” in which everything was composed of four elements—Air, Earth, Fire, and Water. Thinking about the materials available to him, this is not a bad list. But as a predictive model of Nature, it has some obvious shortcomings. Succe...

This paper describes a goal directed discovery system, TREV, which models the disvery of certain quantum properties and conservation laws by physicists in thi.~ century. The program is directed by consistency and completeness constraints, and has the capability of improving and revising its domain theory, and of explaining its knowledge state by these constraints. TREV is capable of formulating...

The study of two spin asymmetries in hadron-hadron collisions probes the details of fundamental particle interactions in ways infeasible to machines with unpolarized collisions. Within reach is how the proton spin is distributed among its constituents through ∆G and ∆q̄. Measuring couplings, furthering our understanding jet structure and uncovering new physics are all among the possibilities ava...

This is the comment to the preprints by G. Ossola and A. Sirlin, hep-ph/0305050, and E.Kh. Akhmedov, hep-th/0204048, who discussed different regularization schemes for calculations of the vacuum energy stored in the zero-point motion of fundamental fields. We show that the contribution of the fermionic and bosonic fields to the energy of the vacuum depends on the physical realization of the vac...
