Advanced

$\eta$ and $\eta'$ Physics

Bijnens, Johan LU (2008)
Abstract
This talk describes the reasons why $\eta$ and $\eta^\prime$ decays are

an interesting topic of study for both theory and experiment. The main

part discusses the results of the recent calculation of $\eta\to3\pi$

at two-loop order in ChPT. Some puzzling aspects of the results

compared to earlier dispersive calculations are highlighted.

I also like to remind the reader of the use of $\eta$ and $\eta^\prime$ decays

for studying the anomaly.
