The main motivation of this article is to try to address such questions as why our universe is as it is from the smallest elementary particles to stars, galaxies and the largest cosmos. We attempt to offer our view on this fundamental problem by introducing energy levels for leptons and quarks as well as for hadrons, and by exploring both essential characteristics of four forces derived using t...

A concise review of the most recent major achievements of elementary-particle physics is given. The successes and problems of gauge theories of the strong and electroweak interactions are discussed. A comparison is made of the possible alternatives in the development of physics in the transition to laboratory energies of the order of a tera-electron-volt. Models of grand unification and superun...

The QCD sector of the system SANC is presented. QCD theoretical predictions for several processes of high energy interactions of fundamental particles at the one-loop precision level for up to some 3and 4-particle processes are implemented.

Inspired by the concept of complementarity, we present a illustrative model for the weak interactions with unbroken gauge symmetry and unbroken supersymmetry. The observable particles are bound states of some more fundamental particles. Supersymmetry is broken at the macroscopic scale of the observable particles by a discrete symmetry but remains exact at the scale of the fundamental particle a...

The results presented at the 28th International Cosmic Ray Conference on neutrino and muon physics are summarized. Neutrinos and muons provide a huge amount of information on particle interactions up to very high energies and on fundamental particle properties. Results on neutrino oscillations in the atmospheric and solar ν sectors are summarized. Oscillations are well established in both secto...

In these lectures I give a short review of the main theoretical ideas underlying the extensions of the Standard Model of elementary particle interactions.

In this article we have summarized the status of the system SANC version 0.41. We have implemented theoretical predictions for many high energy interactions of fundamental particles at the one-loop precision level for up to 4-particle processes. In the present part of our SANC description we place emphasis on an extensive discussion of an important first step of calculations of the one-loop amp...
