| Abstract: | Of the vast array of dark matter candidates proposed during the last decades, the possibility of dark sector(s) has recently received much attention. This class of models introduces a new hidden sector with WIMP-like dark matter particles charged under a new Abelian gauge group. The corresponding gauge boson, dubbed a dark photon, must be lighter than a few GeV to explain recent astrophysical and terrestrial anomalies. Thanks to their large luminosities and low-background environments, low-energy e+e- colliders offer an ideal environment to probe these scenarios, complementing searches for dark matter at the LHC or in direct detection and satellite experiments. In this talk, I'll briefly review the motivation and phenomenology of dark sectors, present recent searches for dark sector particles and discuss future experiments designed to further probe these possibilities. |

 I am currently a Senior Research Fellow in high-energy physics at Caltech, collaborating to the BABAR and Mu2e experiments. I completed my Ph.D. in physics at the University in Geneva in 2005 on studies of non-perturbative QCD at the L3 experiment at LEP. I joined BABAR in 2006, and I am currently convener of the “New Physics Searches group”, focusing on searches for New Physics and dark matter. I recently joined the Mu2e experiment, designed to search for charged lepton flavor violation in muon decays, participating to the construction of the electromagnetic calorimeter.
