Description
Dark sector models can explain the relic abundance of universe and thus constitute attractive scenarios. We present the searches for dark sector particles in B decays at Belle. We also search for the dark Gauge boson Z' and light dark matter chi, in the process e+ e- → mu+ mu- Z' and e+ e- → mu+ mu- chi chi_bar. Other analyses related to dark sector are also covered. The analyses are based on the full data set recorded by the Belle detector at the KEKB e+ e- collider.
