Abstract
Measuring the pionic structure function is of high interest, as it provides a new area for understanding the strong interaction among quarks and testing QCD predictions. To this end, we investigate the feasibility and expected impact of a possible experiment at EicC (Electron-ion collider in China). We show the simulation results on the statistical precision of an EicC measurement, based on the model of leading neutron tagged DIS process and the parton distribution functions of the pion from JAM18 global analysis. The simulation shows that at EicC, the kinematics cover the
range from 0.01 to 1, and the
range from 1 to 50 GeV
, within the acceptable statistical uncertainty. Assuming an integrated luminosity of 50 fb
, in the low-
region (
GeV
), the Monte Carlo data show that the suggested measurement in the whole
range reaches very high precision (
%). To perform such an experiment, only the addition of a far-forward neutron calorimeter is needed.
