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...

Eta, Eta’ and eLSM

We discuss the η-η ′ mixing in the Extended Linear Sigma Model (eLSM).

chi ( c 0 ) and chi ( c 2 ) decays into eta eta , eta eta ‘ , and eta ’ eta ’ final states

The Unitary Executive offers a powerful case for the historical pedigree of the unitary executive theory. Offering an account of presidential practice stemming from George Washington to George W. Bush, the book seeks to ground unitary executive theory with exhaustive historical evidence. Although the authors do not purport to present a history of the presidency, they do provide important and co...
