Abstract

Using a data sample of e+e- collision data corresponding to an integrated luminosity of 108 pb-1 collected with the BESIII detector at a center-of-mass energy of 2.125 GeV, we study the process e+e-→φππ and search for a strangeoniumlike structure Zs decaying into φπ. No signal is observed in the φπ mass spectrum. Upper limits on the cross sections for Zs production at the 90% confidence level are determined. In addition, the cross sections of e+e-→φπ+π- and e+e-→φπ0π0 at 2.125 GeV are measured to be (436.2±6.4±30.1) pb and (237.0±8.6±15.4) pb, respectively, where the first uncertainties are statistical and the second systematic.
