The aim of the workshop is to bring together researchers working in the field of precision electroweak physics to address, in a broad way, how two- or many-photon exchange processes enter into precision electromagnetic and electroweak processes. Access to new physics topics provided by possible future measurements in upgraded experimental facilties will be explored. Particular emphasis will be put on approaches connecting different kinematical regimes.
