f-Dominance of Gravity

A Lagrangian theory is formulated describing the intrinsic mixing of the graviton with a massive $2^{+}$ $f$ meson which interacts universally with hadrons through the stress tensor. The theory is developed as an analog of the well-known $\rho -\gamma$ model of hadron electrodynamics, and in particular a field-current identity is exhibited which equates the massive $2^{+}$ meson with the hadronic energy-momentum tensor. An Einstein-type Lagrangian is used for both spin-2 particles, and general covariance is preserved throughout. The nonlinear coupling of the hadrons to the $f$ meson leads, within the framework of nonpolynomial field theories, to a universal cutoff for strong-interaction physics.
