The status of R value measurement at BESIII

The data samples for R value measurement and QCD experimental study with BESIII from 2.0 to 4.59 GeV have been collected, the total energy points are 130 and the total integrated luminosity is about 1.3 fb−1. With these data, R value and line-shape of the high masses charmonium are being analyzed, and the parameters of Lund area law generator LUARLW is are tuned. In this paper the present status of R value measurement is reviewed.
