    • Observation of psi(3686) -> eta ' e(+)e(-) 

      Kolcu, Onur Buğra (Elsevier Science Bv., 2018)
      Using a data sample of 448.1 x 10(6) psi(3686) events collected with the BESIII detector at the BEPCII collider, we report the first observation of the electromagnetic Dalitz decay psi(3686) -> eta'e(+)e(-), with significances ...
    • 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) ...
