We study e+e-→π+π-hc at center-of-mass energies from 3.90 to 4.42 GeV by using data samples collected with the BESIII detector operating Beijing Electron Positron Collider. The Born cross sections are measured 13 and found be of same order magnitude as those e+e-→π+π-J/ψ but a different line shape. In π±hc mass spectrum, distinct structure, referred Zc(4020), is observed 4.02 GeV/c2. Zc(4020) carries an electric charge couples charmonium. A fit invariant neglecting possible interferences,...
