We present the results of a search for a dark photon decaying to $e^+e^-$ or $mu^+mu^-$ in the babar detector. We find no evidence for such a dark photon and set upper limits on the dark mixing as a function mass, tightening the constraints on the parameter space of several dark sector theories.

One of the most intriguing puzzles in hadron spectroscopy are the numerous charmonium-like states observed in the last decade, including charged states that are manifestly exotic. The $BABAR$ experiment has extensively studied those in B meson decays , initial state radiation processes and two photon reactions. The study of the process $B rightarrow J/psi phi K$, with a search for the resonant states X(4140) and X(4270) in their decays to $J/psi phi$, will be highlighted. The recent results of the Dalitz analysis of $eta_c$ to 3 pseudoscalar mesons, via 2-photon interactions, will be presented in this report
The Heavy Photon Search experiment took its first data in a 2015 engineering run using a 1.056 GeV, 50 nA electron beam provided by CEBAF at the Thomas Jefferson National Accelerator Facility, searching for an electro-produced dark photon. Using 1.7 days (1170 nb$^{-1}$) of data, a search for a resonance in the $e^{+}e^{-}$ invariant mass distribution between 19 and 81 MeV/c$^2$ showed no evidence of dark photon decays above the large QED background, confirming earlier searches and demonstrating the full functionality of the experiment. Upper limits on the square of the coupling of the dark photon to the Standard Model photon are set at the level of 6$times$10$^{-6}$. In addition, a search for displaced dark photon decays did not rule out any territory but resulted in a reliable analysis procedure that will probe hitherto unexplored parameter space with future, higher luminosity runs.

Several types of new-physics models predict the existence of light dark matter candidates and low-mass Higgs states. Previous babar searches for invisible light-Higgs decays have excluded large regions of model parameter space. We present searches fo r a dark-sector Higgs produced in association with a dark gauge boson and searches for a light Higgs in $Upsilon (nS)$ decays.
It has been proposed that an additional U(1) sector of hidden photons could account for the Dark Matter observed in the Universe. When passing through an interface of materials with different dielectric properties, hidden photons can give rise to pho tons whose wavelengths are related to the mass of the hidden photons. In this contribution we report on measurements covering the visible and near-UV spectrum that were done with a large, 14 m2 spherical metallic mirror and discuss future dark-matter searches in the eV and sub-eV range by application of different electromagnetic radiation detectors.
