摘要：
The charged pion form factor, Fπ(Q2), is an important quantity which can be used to advance our
knowledge of hadronic structure. However, due to the lack of a stable pion target, the 
e^+ + p → e^′+ π^+ +n exclusive meson production reaction must be utilized to access this 
information. Ongoing measurements from Jefferson Lab are expected to provide precise Fπ data 
over 0.38 < Q2 < 6.0 GeV2, and up to Q2= 8.5 GeV2 with somewhat lower precision provided non-pole 
backgrounds to the reaction cross-section are sufficiently small. The Electron-Ion Collider
(EIC) may allow the extension of these measurements up to Q2= 35 GeV2, which would enable the
direct observation of QCD’s transition from confinement-dominated physics at large length-scales
to perturbative physics at short-length scales. I will summarize the status of our measurements
at Jefferson Lab, including the various important model tests that are needed to give confidence
in the Fπ result. Our studies of planned measurements at the EIC, using a generator we have 
written specifically for this purpose, will also be presented, including also some of the 
difficulties making L/T-separated cross sections at the EIC impractical, and their possible 
resolution.
