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 x π range from 0.01 to 1, and the Q2 range from 1 to 50 GeV2, within the acceptable statistical uncertainty. Assuming an integrated luminosity of 50 fb-1, in the low-Q2 region(ion(ion of a far-forward neutron calorimeter is needed.

Identifying hidden charm pentaquark signal from non-resonant background in electron–proton scattering

引用

Chinese Physics C 2020年第8期44卷 125-131页

作者： Zhi Yang Xu Cao Yu-Tie Liang Jia-Jun Wu Institute of Modern Physics Chinese Academy of SciencesLanzhou 730000China University of Chinese Academy of Sciences Beijing 100049China School of Physical Sciences University of Chinese Academy of Sciences(UCAS)Beijing 100049China

In this study,we analyze the electroproduction of the LHCb pentaquark states with the assumption that they are resonant *** main concern is to investigate the final state distribution in the phase space to extract a feeble pentaquark signal from a large non-resonant *** results indicate that the signal to background ratio will increase significantly with a proper kinematic cut,which will be beneficial for future experimental analysis.
