Title: Measuring gravitational form factors of proton and pion through deeply virtual threshold phi production
Abstract: Gravitational form factors (GFFs) encode rich information about hadron structure, including the internal partonic spin, mass, pressure and shear force distributions. Though the measurement of GFFs is possible by their relation to GPDs, the extraction is complicated due to the deconvolution problem. The deconvolution problem for the GFFs may be circumvented by considering near threshold production of mesons. Ongoing experiments at Jlab aim at extracting the gluon GFFs from Jpsi photoproduction. We suggest another process to measure the gluon and even strangeness GFFs of the proton from deeply virtual phi meson production near threshold at Jlab and the EIC. Furthermore, we propose a related method to measure the GFFs of the pion in the near threshold production of phi and Jpsi using the Sullivan process.
