V. Kundrat et M. Lokajicek, APPLICABILITY OF MARTINS EQUATIONS IN HIGH-ENERGY ELASTIC HADRON SCATTERING, Physical review. D. Particles and fields, 55(5), 1997, pp. 3221-3224
The validity region of Martin's equations enabling one to determine th
e t dependence of the real part of the elastic hadron amplitude from i
ts imaginary part is critically reexamined. It can be concluded on the
basis of a more precise analysis that quite unjustified and in princi
ple incorrect physical results are obtained if the equations are used
outside this region, i.e., for \t\greater than or similar to 0.15 GeV2
.
