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.
