We investigate the role of correlated $\pi\rho$ exchange in the extraction of matrix elements of the strange vector current in the proton. We show that a realistic isoscalar spectral function including this effect leads to sizeably reduced strange vector form factors based on the dispersion--theoretical analysis of the nucleons' electromagnetic form factors.

On Exclusive Coherent Production of Bosons in Electron-Proton Collisions
A phenomenological 2-to-3 framework is constructed for exclusive boson electroproduction that matches flux-factorized predictions near Q^{2}=0 while capturing finite-Q^{2} effects at larger virtualities.
