Abstract

WOS: 000345356900003, PubMed ID: 25479489, Using data collected with the BESIII detector operating at the Beijing Electron Positron Collider at center-of-mass energies of root s = 4.23, 4.26, and 4.36 GeV, we observe e(+)e(-) -> pi(0)pi(0)h(c) for the first time. The Born cross sections are measured and found to be about half of those of e(+)e(-) -> pi(+)pi(-)h(c) within less than 2 sigma. In the pi(0)h(c) mass spectrum, a structure at 4.02 GeV/c(2) is found. It is most likely to be the neutral isospin partner of the Z(c)(4020)(+/-) observed in the process of e(+)e(-) -> pi(+)pi(-)h(c) being found. A fit to the pi(0)h(c) invariant mass spectrum, with the width of the Z(c)(4020)(0) fixed to that of its charged isospin partner and possible interferences with non-Z(c)(4020)(0) amplitudes neglected, gives a mass of (4023.9 +/- 2.2 +/- 3.8) MeV/c(2) for the Z(c)(4020)(0), where the first error is statistical and the second systematic., National Key Basic Research Program of China [2015CB856700]; Joint Funds of the National Natural Science Foundation of China [11079008, 11179007, U1232201, U1332201]; National Natural Science Foundation of China (NSFC) [10935007, 11121092, 11125525, 11235011, 11079023, 11322544, 11335008]; Chinese Academy of Sciences (CAS) Large-Scale Scientific Facility Program; CAS [KJCX2-YW-N29, KJCX2-YW-N45]; 100 Talents Program of CAS; German Research Foundation DFG [Collaborative Research Center CRC-1044]; Istituto Nazionale di Fisica Nucleare, Italy; Ministry of Development of Turkey [DPT2006K-120470]; Russian Foundation for Basic Research [14-07-91152]; U.S. Department of Energy [DE-FG02-04ER41291, DE-FG02-05ER41374, DE-FG02-94ER40823, DESC0010118]; U.S. National Science Foundation; University of Groningen (RuG); Helmholtzzentrum fuer Schwerionenforschung GmbH (GSI), Darmstadt; WCU Program of National Research Foundation of Korea [R32-2008-000-10155-0], The BESIII Collaboration thanks the staff of BEPCII and the IHEP computing center for their strong support.
