Gravitational $p\to {\Delta }^{+}$ transition form factors in chiral perturbation theory

H. Alharazin, B. -D. Sun, E. Epelbaum +2

The gravitational form factors of the transition from the proton to the ${\Delta }^{+}$ resonance are calculated to leading one-loop order using a manifestly Lorentz-invariant formulation of…
