Experimental review of e+e-ππhc

  • We review the recent BESIII measurement of e+e-ππhc in which its line shape is studied between the center-of-mass energies of 3.9 to 4.42 GeV and an iso-vector charmonium-like state Zc(4020) is observed in the invariant mass of πhc at the BESIII experiment. The charged Zc(4020)± is the second observed Zc state following Zc(3900), while the Zc(4020)0 is the rst observed neutral Zc state. The line shape of (e+e-ππhc) is also re-analyzed in view of searching for the Y state and the existence of the Y(4220) state is con rmed and compared with the previous work of the BESIII experiment.

Abstract: We review the recent BESIII measurement of e+e-ππhc in which its line shape is studied between the center-of-mass energies of 3.9 to 4.42 GeV and an iso-vector charmonium-like state Zc(4020) is observed in the invariant mass of πhc at the BESIII experiment. The charged Zc(4020)± is the second observed Zc state following Zc(3900), while the Zc(4020)0 is the rst observed neutral Zc state. The line shape of (e+e-ππhc) is also re-analyzed in view of searching for the Y state and the existence of the Y(4220) state is con rmed and compared with the previous work of the BESIII experiment.
