Title: Evidence for eikonal zeros in the momentum transfer space
Author: Carvalho, PAS
Menon, MJ
Abstract: We present the results of fitting elastic pp differential cross section data at 23.5 less than or equal to root s less than or equal to 62.5 GeV with a novel analytic parametrization for the scattering amplitude. Making use of a fitting method, the errors from the free parameters are propagated to the imaginary part of the eikonal in the momentum transfer space. A novel systematic study of the effects coming from data at large momentum transfer is also performed. We find statistical evidence for the existence of eikonal zeros in the interval of momentum transfer 5-9 GeV2.
