Asymptotic behaviour of the real part of the scattering amplitude at t not=0
Assuming that the odd-signature amplitude is negligible at high energies the authors derive the expression rho =( pi /logE)(1+(1/f( tau )) tau (df( tau )/d tau )). They note that it is difficult to estimate the finite-energy effects, which would alter the formula, since the imaginary part of the fix...
