This article is about the interplay between the Standard Model of elementary particle physics and neutron β-decay. Since the Fermi decay constant is known from muon decay, the Standard Model describes neutron β-decay with only two additional parameters. One parameter is the first entry |Vud| of the CKMmatrix. The other one is λ, the ratio of the vector coupling constant and the axial vector con...

An elementary introduction to perturbative renormalization and renormalization group is presented. No prior knowledge of field theory is necessary because we do not refer to a particular physical theory. We are thus able to disentangle what is specific to field theory and what is intrinsic to renormalization. We link the general arguments and results to real phenomena encountered in particle ph...

INTRODUCTION Protons, electrons, neutrons, neutrinos and even quarks are often featured in news of scientific discoveries. All of these, and a whole "zoo" of others, are tiny sub-atomic particles too small to be seen even with the microscopes. While molecules and atoms are the basic elements of familiar substances that we can see and feel, we have to "look" within atoms in order to learn about ...

This paper is second one in the series devoted to the calculation of particle masses in the framework of p-adic conformal field theory limit of Topological GeometroDynamics. The concept of topological condensate generalizes the concept of 3-space in radical manner. The various hierarchically ordered levels of the condensate obey effective p-adic topology and fractal considerations motivate the ...

The history of physics from the middle of the 19th century until 2000 is presented. The dominant drive for the development is related to the creation of Quantum Mechanics in the first half of the 20th century. New concepts like the particle-wave duality and the definition of an elementary particle are discussed. The explosion of the number of particles, due to new accelerators, led to the theor...

In preceding papers it was shown that in nonlinear spinor theory cross-sections of elementary particle scattering processes can be calculated only if the state representations and their scalar products are explicitly known. To obtain these quantities, functional quantum theory of the nonlinear spinor field was introducedIn this paper it is demonstrated that the introduction of functional scalar...

Dynamics of quantum field theory can be formulated by functional equations. To develop a complete functional quantum theory the physical information has to be given by functional operations only. The most important physical information of elementary particle physics is the Ä-matrix. In this paper the functional ^-matrix is constructed for the scattering of relativistic dressed particles, i.e. f...

According to the superstring theory the low-energy elementary particle models contain as ingredient the multiplets of chiral and antichiral superfields action of which is given in terms of kählerian effective potential K(¯ Φ, Φ) and chiral W (Φ) and antichiral ¯ W (¯ Φ) potentials. These potentials are found in explicit and closed form within string perturbation theory (see f.e. [1]). Phe-nomen...

The description of the infrared hadron dynamics remains a crucial challenge for elementary particle physics. Whereas perturbative calculations allow for a detailed study of the strong interaction processes at high energies, to date there is no reliable theoretical method which would enable one to handle the hadron dynamics at low energies. However, many physical phenomena are tightly bound to t...

In present paper we construct classical and quantum models of an extended charged particle. One shows that consecutive modelling might be founded on the hollow charged texture which acquires gravitational mass due to the electromagnetic interaction. We demonstrate that such a model has equilibrium states at the radius equal to the classical radius of a charged particle. Also we consider quantum...
