The predictive power of ChPT in electroweak interactions with nucleons (Zoom talk)

Speaker(s) / Presenter(s):
Astrid Hiller Blin, JLaB

The framework of chiral perturbation theory (ChPT) sets an excellent basis for the description of low-energy electroweak processes involving hadrons in general. After a brief introduction to this theory, I will discuss some applications we have worked on, namely the processes of photon- and neutrino-induced pion production close to threshold, and the predictive power therein. Furthermore, I will show that ChPT can be of use also in other physics fields, with the example of setting constraints on CP-violating decay rates by connection to the neutron EDM calculation.
