Explicit Solutions to the Unitarity Relations for Isovector Nucleon Form Factors

Abstract

The explicit one-dimensional integral representations for isovector nucleon form factors are constructed by solving the unitarity relations in terms of the pion form factor and imaginary parts of the t-channel p-wave $\pi N$-scattering amplitudes. The possibility of computation of the high-energy parts of the integrals with the use of the information on the low-energy real parts of the $\pi N$-scattering amplitudes is discussed.
