Abstract
Subject headings
Close
- 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(-) -> phi pi pi and search for a strangeoniumlike structure Z(s) decaying into phi pi. No signal is observed in the phi pi mass spectrum. Upper limits on the cross sections for Z(s) production at the 90% confidence level are determined. In addition, the cross sections of e(+)e(-) -> phi pi(+)pi(-) and e(+)e(-) -> phi pi(0)pi(0) 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.
