英文摘要: The anomalous line shape of the psi(3770) state has resulted in some difficulty in the determination of the R value for the continuum light hadron production in the resonance energy range. We parameterize the asymmetric line shape using a Fano-type formula and extract the R-uds value to be 2.156 +/- 0.022 from the data of BESIII Collaboration in the energy region between 3.650 and 3.872 GeV. The small discrepancy between experiment and theory is removed. The cross sections of the e(+)e(-) -> hadrons with continuum light hadron production subtracted are given and compared to the data of the e(+)e(-) -> D (D) over bar reaction. (C) 2015 The Authors.
