Description
The electromagnetic form factor, especially its asymptotic behavior for large momentum transfer ($Q^2$), of pion and kaon provides crucial insight into the partonic structure of a Nambu-Goldstone boson in the strong interaction. Studies of the electromagnetic form factor of pion and kaon up to $Q^2$ ~ 6 GeV$^2$ are underway at the ongoing JLab12 experiment and its measurements in an extended range of $Q^2$ ~ 10 – 40 GeV$^2$ are planned at the future Electron-Ion Collider (EIC). For the first time, we will present results for the pion and kaon electromagnetic form factor in the range of $Q^2$ ~ 0 – 10 and 28 GeV$^2$, respectively, from state-of-the-art lattice QCD calculations carried out using physical values of up, down, and strange quark masses. These results will provide benchmark QCD predictions for model-based studies and the experimental measurements, in particular at the boundaries between the JLab12 and the EIC.
