  "abstract": "<p>Using data samples collected at center-of-mass energies of \u221as = 4.009, 4.230, 4.260, and 4.360 GeV with the BESIII detector operating at the BEPCII collider, we perform a search for the process e+e\u2212 \u2192 \u03b3\u03c7cJ (J=0, 1, 2) and find evidence for e+e\u2212 \u2192 \u03b3\u03c7c1 and e+e\u2212 \u2192 \u03b3\u03c7c2 with statistical significances of 3.0\u03c3 and 3.4\u03c3, respectively. The Born cross sections \u03c3B(e+e\u2212 \u2192 \u03b3\u03c7cJ), as well as their upper limits at the 90% confidence level (C.L.) are determined at each center-of-mass energy.</p>",
