Search for the reaction e⁺e⁻ → _χcJπ⁺π⁻ and a charmoniumlike structure decaying to _χcJπ^± between 4.18 and 4.60 GeV

We search for the process e+e−→χcJπ+π− (J=0, 1, 2) and for a charged charmoniumlike state in the χcJπ± 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 χcJπ+π− 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 χcJπ± mass.
