• The analytic properties of the Born amplitude of a specific scattering process involving an infinite-component field is investigated. Our infinite-component field lies on a pair of linearly rising Regge trajectories. We treat the scattering process between the ground state of this multiplet and a scalar particle where the whole multiplet appears as the intermediate state. The partial wave expansion allows Watson-Sommerfeld transformation and we get the Regge pole term. However, when we continue the amplitude analytically into the crossed channel region, we met the following problems: (a) divergence of background integral, and (b) emergence of unphysical solutions.
