چکیده
A bstract We compute the leading terms of spectral action for a noncommutative geometry model that has no fermion doubling. The triple describing it, which is chiral and allows CP-symmetry breaking, Dirac operator not product type. Using Wick rotation we derive explicitly Lagrangian from flat metric, demonstrating appearance topological ? -terms electroweak gauge fields.

A lattice fermion without doubling
A free fermion without doubler is formulated on 1+D dimensional discrete Minkowski space-time. The action is not hermitian but causes no harm. In 1+3 dimensional massless case the equation describes a single species of Dirac particle in the continuous space-time limit. In 1+1 dimensional massless case the equation is the same as the automaton equation by ’t Hooft and describes a chiral fermion....

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...

Electroweak baryogenesis is addressed within the context of the standard model of particle physics. Although the minimal standard model has the means of fulfilling the three Sakharov’s conditions, it falls short to explaining the making of the baryon asymmetry of the universe. In particular, it is demonstrated that the phase of the CKM mixing matrix is an insufficient source of CP violation. Th...
