In several self-coupled quantum field theories when treated in semi-classical limit one obtains solitonic solutions determined by topology of the boundary conditions. Such solutions, e.g. magnetic monopole in unified theories [1] [2] or the skyrme model of hadrons have been proposed as possible non-perturbative bound states which remain stable due to topological quantum numbers. Furthermore whe...

The top quark seesaw mechanism offers a method for constructing a composite Higgs field without the usual difficulties that accompany traditional technicolor or topcolor theories. The focus of this article is to study the phenomenology of the new physics required by this mechanism. After establishing a set of criteria for a plausible top quark seesaw theory, we develop two models, the first of ...

It is a common assertion that quenched lattice QCD qualitatively produces many of the features found in continuum full QCD. However, a quenched simulation is expected to include topological gauge configurations which produce exact fermion zero modes. Not suppressed by the missing fermion determinant, such modes will cause divergent behavior in the small mass limit of the chiral condensate. Surp...

Let γ be an automorphism of a fermion-boson C∗-system. If γ commutes with an arbitrary asymptotically abelian group of automorphisms, then it preserves the fermion grading symmetry.

We give an interpretation to the issue of the chiral determinant in the heatkernel approach. The extra dimension (5-th dimension) is interpreted as (inverse) temperature. The 1+4 dim Dirac equation is naturally derived by the Wick rotation for the temperature. In order to define a “good” temperature, we choose those solutions of the Dirac equation which propagate in a fixed direction in the ext...
