Search for the reaction e+ e- ? ?cJ?+?- and a charmoniumlike structure decaying to ?cJ?± between 4.18 and 4.60 GeV

Abstract

We search for the process e(+)e(-) -> chi(cJ)pi(+) pi(-) (J = 0, 1, 2) and for a charged charmoniumlike state in the chi(cJ)pi +/- subsystem. The search uses datasets collected with the BESIII detector at the BEPCII storage ring at center-of-mass energies between 4.18 GeV and 4.60 GeV. No significant chi(cJ)pi(+) pi(-) signals are observed at any center-of-mass energy, and thus upper limits are provided which also serve as limits for a possible charmoniumlike structure in the invariant chi(cJ)pi +/- mass.
