Exact Static-Model Bootstrap Solutions for Arbitrary 2 × 2 Crossing Matrices
James T. Cushing · Journal of Mathematical Physics · 1969
Explicit, exact solutions, satisfying a bootstrap criterion in the form of Levinson's theorem and having real coupling constants, are exhibited for the two-channel Low equation for arbitrary real values of the parameter appearing in the 2 × 2 crossing matrix. This disproves a claim made recently in the literature that the bootstrap criterion will restrict values of the crossing-matrix parameter to those corresponding to the internal-symmetry group SU2. It is demonstrated that the previous alleged proof is inconclusive.
