Spontaneous symmetry breaking in Reggeon field theory

Institution:California Institute of Technology, Pasadena, California 91109, USA
Abstract:We consider a Reggeon field theory when the bare or input Regge intercept αO is greater than one. This corresponds to a negative mass squared term in conventional field theory and allows for a spontaneous symmetry break-down. A theory with Regge intercept at one emerges, restoring the Froissart bound by t-channel considerations alone. In our elementary example the resulting bare trajectory is nearly of the square root variety familiar from s-channel eikonalization of models which violate the Froissart bound.
