Abstract

Meson-exchange current contributions of the strangeness radius of 4He are computed in the one-boson exchange approximation. It is found that these contributions introduce a ≳ 10% correction to the one-body contribution. They should not, therefore, hamper the extraction of the nucleon strangeness radius from the parity-violating electron-4He asymmetry.
