Abstract
Vector mesons and the W gauge boson share some common features, such as the spin and a very short lifetime. The electromagnetic properties of the W are linked to its gauge nature and thus a big effort has been devoted to measure them, while accounting for its instability. In this work, we elaborate on how these ideas can be translated to study vector mesons. We focus in the unstable property of such states and the restrictions from electromagnetic gauge invariance, describing the differences and similarities. Then, we describe the four pseudoscalars electroproduction as an analog to the e+e-→4fermions process, used to study the electromagnetic properties of the W boson. We point out that the current experimental capabilities are reaching the possibility to measure the magnetic dipole moment of light vector mesons.
