Although the Standard Model of elementary particles is well established, strong interactions are not yet fully under control. We believe QCD is the field theory capable of describing them, but we are not yet capable, in most cases, to make exact predictions. Systems that include heavy quark-antiquark pairs (quarkonia) are an ideal and unique laboratory to probe both the high energy regimes of Q...

We discuss how various properties of dilaton black holes depend on the dilaton coupling constant a. In particular we investigate the a-dependence of certain mass parameters both outside and in the extremal limit and discuss their relation to thermodynamical quantities. To further illuminate the role of the coupling constant a we look at a massless point particle in a dilaton black hole geometry...

Observational diagnostics are constructed which reflect the underlying topology of Planckian space-time, and are directly related to phenomena on much larger scales. Specific predictions are made for the masses of elementary particles, coupling constants, quark confinement , black hole states, and the cosmological constant. In particular, a mass of 131.6 GeV is found for the Higgs boson. The ma...

A constraint from b → sγ process to the minimal supersymmetric standard model is derived in the light stop region where the coupling between the lighter stop and the Z boson vanishes due to the left-right mixing of the stop states. It is pointed out that although some region in the parameter space is excluded from this process there remains a large parameter space where the amplitude of the b →...

Lanczos’s quaternionic interpretation of Dirac’s equation provides a unified description for all elementary particles of spin 0, 1 2 , 1, and 3 2 . The Lagrangian formulation given by Einstein and Mayer in 1933 predicts two main classes of solutions. (1) Point like partons which come in two families, quarks and leptons. The correct fractional or integral electric and baryonic charges, and zero ...

The mass-generation mechanism is the most urgent problem of the modern particle physics. The discovery and study of the Higgs boson with the Large Hadron Collider at CERN are the highest priority steps to solve the problem. In this paper, the Standard Model Higgs mechanism of the elementary particle mass generation is reviewed with pedagogical details. The discussion of the Higgs quadric self-c...

In the standard model (SM) the condition that the Higgs mass parameter vanishes is stable under radiative corrections and yields a theory that can be renormalized using dimensional regularization. Thus, this model allows to predict the Higgs boson mass. However, it is phenomenologically ruled out in its minimal version. Here, we present a phenomenologically viable, minimal extension which only ...

It has been more than twenty years since the basic idea of the standard model(SM) of elementary particle theory was proposed. This theory is based on two fundamental principles, i.e. the gauge principle and the Higgs mechanism. From recent experiments it is now clear that strong and electroweak interactions are described by an SU(3)×SU(2)×U(1) gauge theory. On the other hand, little is known ab...
