  In the Cohen-Glashow Very Special Relativity we exhibit possible
modifications to the Maxwell theory and to the quantum electrodynamics
Lagrangian in some generality, and discuss characteristic features depending on
the modifications. Modified gauge transformations in SIM(2)-invariant theories
are introduced, and in these theories gauge fields with two polarization states
can have nonzero mass. Also considered are SIM(2)-covariant modifications to
the Proca-type field equations for a massive spin-1 particle.
