Abstract
Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Using a novel representation for the Martin's real-part formula without the full scaling property, an almost model-independent description of the proton proton differential cross-section data at high energies (19.4 GeV-62.5 GeV) is obtained. In the impact parameter and eikonal frameworks, the extracted inelastic overlap function presents a peripheral effect (tail) above 2 fin and the extracted opacity function is characterized by a zero (change of sign) in the momentum transfer space, confirming results from previous model-independent analyses. Analytical parametrization for these empirical results are introduced and discussed. The importance of investigations on the inverse problems in high-energy elastic hadron scattering is stressed and the relevance of the proposed representation is commented. A short critical review on the use of Martin's formula is also presented. 26 19 3219 3247 Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) FAPESP [11/00505-0, 09/50180-0, 07/05953-5]
