In this framework, the imaginary part of the $\\Upsilon$-p forward scattering amplitude is obtained from $\\gamma p \\to \\Upsilon p$ 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 $\\Upsilon$-p scattering length.
