Descrição: We present a dispersive analysis with the aim to extract the Υ−p scattering length from γp → Υp experiments. In this framework, the imaginary part of the Υ−p forward scattering amplitude is obtained from γp → Υp cross section measurements and is constrained at high energies from existing HERA and LHC data. Its real part is calculated through a once-subtracted dispersion relation, and the subtraction constant is proportional to the Υ−p scattering length. We perform a feasibility study for Υ photoproduction experiments at an Electron-Ion Collider and discuss the sensitivity and precision that can be reached in the extraction of the Υ−p scattering length.
