Classical electroweak decay of techni-baryon in the soliton model with a vector field

Classical behaviour of techni-baryon is investigated in the framework of a nonlinear (gauge) σ model with the vector field. A critical mass, Mcr, is calculated numerically, techni-baryons with higher masses have a classical instability with respect to an anomalous electro-weak decay with nonconservation of the baryonic number. It is shown that Mcr depends weakly on the model parameters; it is within a region of 12-15 TeV
