- (5).Our metric is given by δμν(μ,ν=1,2,3,) (μ, ν=1, 2, 3) andx 3=it. Naturally the introduction of a suitable mass scale is necessary and in particular we shall work in units for which a normal Reggeon trajectory (f, ϱ) slope is equal to unity. This is a natural choice, for example in dual models.Google Scholar
- (7).Although our final expressions are formally identical to those exhibited in—ref.(4). they are essentially different since our vacuum expectation value is imaginary and the spontaneous symmetry breaking occurs not from a pomeron intercept above one but one below one. In both cases the final intercept is one.ADSCrossRefGoogle Scholar
