Positivity as a constraint on the positions of the zeros of theK p forward scattering amplitude

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

Stringent constraints on the positions of the zeros of theK p forward scattering amplitude in the complex energy plane are obtained using only information on the modulus of the amplitude on its cuts, together with the requirement of positivity of the imaginary part of the amplitude in the physical region.
