Summary
A complete analysis is performed of the recent pp elastic
data at 7 TeV in terms of its real and imaginary amplitudes,
that are fully disentangled, consistently with dispersion
relations for amplitudes and for slopes.
Real and imaginary slopes B(R) and B(I), treated as independent
quantities, influence the whole t-range and the determination of
the total cross section. The treatment includes prediction for
the universal perturbative tail at large |t|.
New generalized expression is derived for the Coulomb phase.
Comparison is made of the values of total cross section and
B(I) obtained in forward and full-t approaches.
