Description
At BESIII, the R value is measured with the corresponding c.m. energy going from 2.2324 to 3.6710 GeV by measuring the inclusive hadronic cross section. An accuracy of better than 2.6% below 3.1 GeV and 3.0% above is achieved in the R values. Besides, the measurements of normalized differential cross sections of inclusive hadrons as a function of hadron momentum are performed at BESIII, for pi0, Ks, eta etc, which provide crucial information for the fragmentation Function (FF) describing the hadronization process.
