10 Sep 2020 | Abstract: | Measuring the pionic structure function is of high interests as it provides a
new area for understanding the strong interaction among quarks and to test the
QCD predictions. To this purpose, we investigate the feasibility and the
expected impacts of a possible measurement on EicC. We show the simulation
result on the statistical precision of an EicC experiment, based on the model
of leading neutron tagged DIS process and the dynamical parton distribution
functions of pion. The simulation shows that at EicC, the kinematic covers a
$x_{pi}$ range from 0.01 to 1, and a $Q^2$ range from 1 GeV$^2$ to 50 GeV$^2$,
within the acceptable statistical uncertainties. Assuming an integrated
luminosity of 50 fb$^{-1}$, in the low $Q^{2}$ region ($<10$ GeV$^2$), the MC
data show that the measurements in the whole $x_{
mpi}$ range reach very high
precisions ($<3$\%). To perform such an experiment, only the addition of a
far-forward neutron calorimeter is needed. | Source: | arXiv, 2009.04956 | Services: | Forum | Review | PDF | Favorites |
