We present a lattice QCD calculation of the electromagnetic form factor of the pion in the timelike region.
This calculation was performed on a lattice with N=2+1 dynamical quark flavors, with a heavier than physical pion mass of 284 MeV.
At this pion mass, the rho meson main contribution to pion-pion scattering and the timelike form factor appears in the elastic energy region.
The scattering phase-shift was also extracted in the inelastic region containing isovector kaon-kaon interactions, allowing future work to study the form factor in the coupled channel energy region from lattice QCD.
