Beschreibungen/Notizen

• In this report, we search for a dark vector gauge boson U' that couples to quarks in the decay chain D*+ → D0π+,D0 → KS0η,η → U'γ , U' → π+π- . No signal is discovered and we set a mass-dependent limit on the baryonic fine structure constant of 10-3-10-2 in the U' mass range of 290 to 520MeV/c2 . This analysis is based on a data sample of 976fb-1 collected by the Belle experiment at the KEKB asymmetric-energy e+e- collider.
