I review theoretical motivations for the experimental searches of new very weakly coupled states, and argue why this will continue to be an important part of the precision and intensity frontier programs.

APEX is a fixed target experiment at Thomas Jefferson National Accelerator Facility (JLab) in Virginia, USA, that searches for a new gauge boson (A') with sub-GeV mass and coupling to ordinary matter of g' ~ (10^-2 - 10^-6) e. Electrons impinge upon a fixed target of high-Z material to produce an A' via a process analogous to photon bremsstrahlung, which then decays to an e+ e- pair that is...
