The reaction $\pi N\to \pi \pi N$ in chiral effective field theory with explicit $\Delta \left(1232\right)$ degrees of freedom
The reaction $\pi N\to \pi \pi N$ in chiral effective field theory with explicit $\Delta \left(1232\right)$ degrees of freedom
The reaction πN→ππN is studied at tree level up to next-to-leading order in the framework of manifestly covariant baryon chiral perturbation theory with explicit Δ(1232) degrees of freedom. Using total cross-section data to determine the relevant low-energy constants, predictions are made for variou...

The reaction πN→ππN is studied at tree level up to next-to-leading order in the framework of manifestly covariant baryon chiral perturbation theory with explicit Δ(1232) degrees of freedom. Using total cross-section data to determine the relevant low-energy constants, predictions are made for various differential as well as total cross sections at higher energies. A detailed comparison of results based on the heavy-baryon and relativistic formulations of chiral perturbation theory with and without explicit Δ degrees of freedom is given. |
