Eta and Eta’ Physics
This talk describes the reasons why η and η decays are an interesting topic of study for both theory and experiment. The main part discusses the results of the recent calculation of η → 3π 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 η and η decays for studying the anom...
متن کاملResults from the KLOE collaboration : study of the eta / eta ’ mesons
The KLOE experiment has successfully completed its data taking in March 2006 with a total integrated luminosity of about 2.5 pb −1. We report the results on the pseudoscalars η/η mesons, such as the η meson mass measurement, the dynamics of η → 3π, the η − η mixing angle, and the measurement of the rare Branching Ratio for the η → π + π − e + e − decay.

متن کاملL–eta–invariants and Their Approximation by Unitary Eta–invariants
Cochran, Orr and Teichner introduced L–eta–invariants to detect highly non–trivial examples of non slice knots. Using a recent theorem by Lück and Schick we show that their metabelian L–eta–invariants can be viewed as the limit of finite dimensional unitary representations. We recall a ribbon obstruction theorem proved by the author using finite dimensional unitary eta–invariants. We show that ...
