Many extensions of the Standard Model introduce an additional U(1) interaction, which is mediated by a U(1) boson, often by a Higgs mechanism adding a dark Higgs (or dark Higgses) to the models. This gauge boson, also known as the "Dark Photon", typically has very weak coupling to Standard Model particles. Experimental results from direct Dark Matter searches, (e.g. DAMA/LIBRA) and other...

3. Search for dark photon and dark Higgs at BABAR

We have searched for a dark photon produced in e+e- collisions and radiating a dark Higgs. The resulting 6-fermion final state is reconstructed in leptonic and leptonic+hadronic channels. We find no signal and set tight limits on the parameters of the model.

16. Search for dark higgsstrahlung processes at KLOE

We searched for the existence of a higgsstrahlung process in a secluded sector, possibly leading to a dark photon and a dark Higgs boson final state. Using the KLOE detector at DAFNE, we investigated the case in which the dark Higgs boson is lighter than the dark photon U and thus escapes detection, showing up as missing energy, and the dark photon U decays in a muon pair. We will report the...
