Kaons are heavy enough to have an interesting range of decay modes available to them, and light enough to be produced in sufficient numbers to explore rare modes with satisfying statistics. Kaons and their decays have provided at least two major breakthroughs in our knowledge of fundamental physics. They have revealed to us CP violation,l and their lack of flavor-changing neutral interactions w...

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...

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.

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 ...

The discovery of anomalous behavior in data collected at high energy physics experiments could provide non-SUSY and non-Higgs explanations to questions associated with the Standard Model and provide deeper understanding to the fundamental particles and interactions in nature. Such questions include whether quarks and leptons are composite particles, the existence of extra dimensions, and the an...

Using the interquark potential we obtain a formula for the mass spectrum of elementary particles. The simple formula gives the masses of all known elementary particles with an error of about three percent or less. This includes the recently discovered Ds(2317) and 1.5GeV Pentaquark particles. One of the problems that has eluded a solution is that of a mass spectrum for elementary particles. Suc...

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...

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.

The most fundamental to the elementary particles is the mass they posses and it would be of importance to explore a possible relationship amongst their masses. Here, an attempt is made to investigate this important aspect irrespective of their nature or scheme of classification. We show that there exists a striking tendency for successive mass differences between elementary particles to be clos...
