Search for the "Dark Photon" and the "Dark Higgs" at Belle    [PDF]

Igal Jaegle, for the Belle Collaboration

The expected sensitivity of Belle is reported for the Dark Photon, $A$, and Dark Higgs, $h'$ searches, for mass ranges, respectively of 0.27 $< m_A <$ 3 GeV/c$^2$ and 0.54 $< m_{h'} <$ 10 GeV/c$^2$. The Dark Photon and Dark Higgs will be searched for in the Higgs-strahlung channels: $e^+e^- \rightarrow Ah'$, with $h' \rightarrow AA$ and $A \rightarrow l^+l^-$ (with $l$ = $e$ or $\mu$). Results will be unblinded soon.
