Abstract

The decay Zc(3900)-->omega pi+- is searched for using data samples collected with the BESIII detector operating at the BEPCII storage ring at center-of-mass energies sqrt(s)=4.23 and 4.26 GeV. No significant signal for the Zc(3900)± is found, and upper limits at the 90% confidence level on the Born cross section for the process e+e- -->’Zc(3900)±pi-+ -->omega pi+pi- are determined to be 0.26 and 0.18 pb at sqrt(s)=4.23 and 4.26 GeV, respectively.
