Pion photo- and electroproduction in relativistic baryon ChPT
arXiv:1402.0656 · doi:10.1051/epjconf/20147304012
Abstract
We present a calculation of pion photo- and electroproduction in manifestly Lorentz-invariant baryon chiral perturbation theory up to and including order q^4. We fix the low-energy constants by fitting experimental data in all available reaction channels. Our results can be accessed via a web interface, the so-called chiral MAID.
