Evidence for e+e-→γηc (1S) at center-of-mass energies between 4.01 and 4.60 GeV

We present first evidence for the process e+e−→γηc(1S) at six center-of-mass energies between 4.01 and 4.60 GeV using data collected by the BESIII experiment operating at BEPCII. We measure the Born cross section at each energy using a combination of twelve ηc(1S) decay channels. We also combine all...
