Recent progress on two-boson exchange effects in electron scattering

Peter Blunden
University of Manitoba, Canada

This talk will be a review of recent work by our group and others on 
the role of two-boson exchange in elastic electron-nucleon scattering, 
focusing in particular on hadronic frameworks suitable for describing 
data at low and moderate Q^2. This will include the effects of 
two-photon exchange (TPE) on elastic form factors, and the interference 
of TPE and gamma-Z exchange on parity-violating form factors.
