Description
Pion-Photoproduction and other elastic processes are analyzed in chiral effective field theory around threshold. We extend the work by Lenkewitz et. al. to include the chiral SMS potential with uncertainty estimation based on cutoff variation. In particular we consider as targets ${}^3\mathrm{He},\;{}^4\mathrm{He} $ and ${}^6\mathrm{Li}$ which enter through their probability density amplitudes which are calculated separately and reused for different processes.
The computational complexity of probability density calculations for $A\geq 5$ body systems requires the use of a similarity renormalization group transform and a corresponding back transform, the details of which are discussed.
This work is conducted in collaboration with Harald Griesshammer (GW), Andreas Nogga, and Xiang-Xiang Sun (FZ Julich).
