Electromagnetic three-nucleon form factors in the Covariant Spectator Theory

I will give a short overview of the basic features of the Covariant Spectator 
Theory and its application to the two- and three-nucleon systems.  In this 
framework, pure one-boson-exchange models of the two-nucleon interaction have 
been found to be very successful in describing the two-nucleon data below the 
pion-production threshold. The three-nucleon binding energy is predicted 
correctly without additional three-nucleon forces. I will show first results 
for the electromagnetic three-nucleon form factors, which represents an 
important test of the Covariant Spectator Theory's ability to describe the 
structure of the three-nucleon bound states.
