We discuss the possible applications supersymmetric theories might nd in the eld of elementary particle physics. The supersymmetric generalization of the SU(3) SU(2) U(1) standard model is discussed in detail. Special attention has been devoted to the question of gauge coupling constant uni cation in the framework of supersymmetric grand uni ed models. * Lecture given at the conference "Gauge T...

The top quark with its mass of about 172 GeV/c is the most massive fundamental particle observed by experiment. In this talk we highlight the most recent measurements of several top quark properties performed with the CDF detector based on data samples corresponding to integrated luminosities up to 1 fb. These results include a search for top quark pair production via new massive resonances, me...

In this paper finite-dimensional Lorentz covariant bifurcation equations are constructed and their properties, solutions, and gradient structures are examined. The possible applications of these ideas and techniques to elementary particle physics are considered.

A pedagogical introduction is given to attempts to formulate a more fundamental theory of elementary particles than that provided by the standard model. After a review of the basic elements of the standard model, its unsatisfactory features, and ideas to modify them will be discussed. An introduction to Technicolour, t-quark condensates, supersymmetric models, GUT's and a brief comment on compo...

Some Cosmological models propose that elementary particles were created during the cooldown of the universe after the “Big Bang”, through a series of symmetry breaking phase transitions[1]. According to these models, these elementary particles are “topological defects” of the cold, ordered phase in which the universe is found today. The equations describing these phase transition of the univers...

There is space for new ideas of the essence and the entity of time. The article refers to our time concept as a special wave type and presents results of our investigations on this subject. Thus, time defined as waves and an energy carrier could give explanation to multiple unclear phenomena. It could explicate gravity, organization in the planetary systems and light speed limit. A hypothesis t...

We investigate the muon neutrino event rate in km neutrino telescopes due to a number of galactic supernova remnants expected on the basis of these objects’ known γ-ray signals. We evaluate the potential of these neutrino signals to exhibit evidence of the sub-dominant neutrino oscillations expected in various neutrino mixing schemes including pseudo-Dirac scenarios and the Exact Parity Model. ...

In this article I summarize some aspects of the current status of the field of high energy physics and discuss how the next generation of high energy colliders will aid in furthering our basic understanding of elementary particles and interactions among them, by shedding light on the mechanism for the spontaneous breakdown of the Electroweak Symmetry.

During the past one hundred years three related elementary particles– the electron, the muon, and the tau–were discovered by very different scientific techniques. The author, who received the Wolf Prize and the Nobel Prize for the discovery of the tau, uses this history to discuss certainty and uncertainty in the practice of science. While the emphasis is on the practice of scientific research,...

In this talk I briefly explain the concept of the structure function of a photon (the best known boson). Then I review some of the current experimental evidence which confirms the existence of ‘strong’ interactions of photon suggested by this idea. I end by pointing out how the photon ‘structure’ has important implications for the interactions of high energy photons and hence for the design of ...
