    • Study of the Dalitz decay J/psi -> e(+)e(-)eta 

      Kolcu, Onur Buğra (Amer Physic Soc., 2019)
      We study the electromagnetic Dalitz decay J/psi -> e(+)e(-)eta and search for dielectron decays of a dark gauge boson (gamma') in J/psi -> gamma'eta with the two q decay modes eta -> gamma gamma and eta -> pi(+)pi(-)pi(0) ...
