Many types of physics beyond the standard model include an extended electroweak gauge group. If these extensions are associated with flavor symmetry breaking, the gauge interactions will not be flavor-universal. In this note we update the bounds placed by electroweak data on the existence of flavor non-universal extensions to the standard model in the context of topcolor assisted technicolor (T...

New string models in D = 4 space-time extended by tensor central charge coordinates zmn are constructed. We use the zmn coordinates to generate string tension using a minimally extended string action linear in dz mn. It is shown that the presence of zmn lifts the light-like character of the tensionless string worldsheet and the degeneracy of its induced metric. We analyse the equations of motio...

By considering the master equation of asymmetric exclusion process on a one-dimensional lattice, we obtain the most general boundary condition of the multi-species exclusion processes in which the number of particles is constant in time. This boundary condition introduces the various interactions to the particles, including ones which have been studied yet and the new ones. In these new models,...
