Descrizione
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 status of the analysis.
