abstract
We discuss the nucleon to higher-spin $N$- and $\Delta$-resonance transitions by pions and photons. The higher-spin baryons are described by Rarita-Schwinger fields and, as we argue, this imposes a stringent consistency requirement on the form of the couplings. Popular $\pi N\Delta$ and $\gamma N\Delta$ couplings are inconsistent from this point of view. We construct examples of consistent interactions with the same nonrelativistic limit as the conventional ones.

Differential and total cross sections are obtained for fermion-fermion scattering in the Rarita-Schwinger model with Yukawa-like coupling at zero and finite temperatures, in both short-range and long-range limits.
