New Solution for BAU George W.S. Hou (NTU) 2nd Open sBelle, 7/3/08 17 “I must say that I am very skeptical that the new Belle result is new physics -- a larger than expected color suppressed amplitude is an explanation that is ready at hand. On the other hand, I felt that it was necessary to push the new physics interpretation when writing for the Nature audience, people outside of high energy physics, because this is why the result is potentially newsworthy.” Peskin (private communication) color suppressed Ya, ya!   anyway !
