Higgs Model without Elementary Scalars
A model of interaction of massless vector and spinor fields is considered. With the use of Bogolyubov quasi-average method we study a possibility of a dy-namical breaking of the initial symmetry. Assuming the existence of effective cutoff Λ, we show, that there exists a solution, which breaks gauge symmetry of the theory. Instead of Higgs scalars fermion-antifermion tachion bound states are pre...

متن کاملSize Competitive Meshing Without Large Angles
We present a new meshing algorithm for the plane, Overlay Stitch Meshing (OSM), accepting as input an arbitrary Planar Straight Line Graph and producing a triangulation with all angles smaller than 170◦. The output triangulation has competitive size with any optimal size mesh having equally bounded largest angle. The competitive ratio is O(log(L/s)) where L and s are respectively the largest an...
متن کاملDynamical Higgs Mechanism without Elementary Scalars: A Lesson from Instantons
The generation of gauge–dependent fermion vacuum condensates in Yang– Mills theory would dynamically break the gauge symmetry and thus provide an alternative to the Higgs mechanism in unified theories. We explore a simple example: instanton-induced quark pair (diquark) condensation in QCD with 2 flavors and Nc colors. We do find diquark condensates in the vacuum, but only for Nc = 2, where they...
متن کامل/ 9407029 Mass Generation for Gauge Fields without Scalars
We present an alternative to the Higgs mechanism to generate masses for nonabelian gauge fields in (3+1)-dimensions. The initial Lagrangian is composed of a fermion with current-current and dipole-dipole type self-interactions minimally coupled to non-abelian gauge fields. The mass generation occurs upon the fermionic functional integration. We show that by fine-tuning the coupling constants th...
