A force beyond the Standard Model - Status of the quest for hidden photons

Abstract

In this note we discuss the search for new gauge forces beyond the Standard Model. In particular we give an overview for the simplest case of a new U(1), kinetically mixed with the Standard Model photon (hypercharge boson), a so-called hidden photon (also known as dark photon, heavy photon or A').
