Determination of the number of ?(3686) events at BESIII
(Institute of Physics Publishing, 2018)
The numbers of ?(3686) events accumulated by the BESIII detector for the data taken during 2009 and 2012 are determined to be (107:0±0:8) ×106 and (341:1±2:1)×106 , respectively, by counting inclusive hadronic events, where ...
