The quest for CP violation in K decays – a marathon
The discovery of CP violation raised many more questions than it gave answers. Some of the experimental questions were: Is CP violation in KL → π0π0 decay different from that in KL → π+π− decay? Is there a CP asymmetry in semileptonic KL decays? How do we detect pure T violation? What about other CP and T violating observables like spin correlations
This field of physics has been a vibrant one producing fascinating results for the past 40 years – like in an Olympic marathon: there was much at stake; truly major discoveries have been made; some have been rewarded; others were left by the way ...
