Chiral theory of \(\rho\)-meson gravitational form factors
- The low-energy chiral effective field theory of vector mesons and Goldstone bosons in an external gravitational field is considered. The energy-momentum tensor is obtained, and the gravitational form factors of the \(\rho\)-meson are calculated up to next-to-leading order in the chiral expansion. This amounts to considering tree-level and one-loop order diagrams. The chiral expansion of the form factors at zero momentum transfer, as well as of the slope parameters, is also performed. Also, the long-range behavior of the energy and internal force distributions is obtained and analyzed.
