What is an elementary particle in the first-quantized Standard Model?

چکیده
The purpose of this paper is to elucidate the concept of an elementary particle in the first-quantized Standard Model. The emphasis is upon the mathematical structures involved, rather than numerical computations. After the general concepts and philosophical outlook are introduced in the opening section, Section 2 addresses the question of what a free elementary particle is, paying particular attention to the relationships between the configuration representation and momentum representation. Section 3 deals with gauge fields, Section 4 deals with interactions between particles and gauge fields, Section 5 deals with composite systems, and Section 6 deals with the representation of Baryons, Mesons, and Hadrons. Section 7 addresses the interpretational question of whether an elementary particle has only one intrinsic state, and Section 8 attempts to elucidate what an interacting elementary particle is in the Standard Model.

Momentum creation by vortices in 3 He experiments as a model of primordial baryogenesis. An important problem in cosmology is why the universe contains so much more matter than antimatter. Such an imbalance can result from processes in which baryon number is not conserved. These may have occured during the electroweak phase transition in the early universe when elementary particles first acquir...

The idea that the elementary particles might have the symmetry of knots has had a long history. In any modern formulation of this idea, however, the knot must be quantized. The present review is a summary of a small set of papers that began as an attempt to correlate the properties of quantized knots with empirical properties of the elementary particles. As the ideas behind these papers have de...

The paper is devoted to a description of quantum group structures in the geometric quantization of a self-interacting string field, which appear under a transition from a tree-level of the theory to the account of loop effects in nonperturbative quantum field theory of strings. Theory of strings, which is the most perspective approach to the unification of Standard Model and its supergeneraliza...

Our present-day theory for fundamental processes in Nature— and by this I mean our descriptions of elementary particles and forces—is phenomenally successful. Experimental data confirms theoretical prediction; where accurate calculations and experiments are attainable, agreement is achieved to many— six or seven—significant figures. Table 1 shows two examples. Of course mostly such precision ca...
