### CKM and New Physics II

From Soni's table below we see that the clean penguin estimates suggest a value less than the $0.66$ of current measurement, which is even further from the incorrect QCD prediction. Taking this constraint seriously, we are led to a value for $\textrm{sin} 2 \beta$ that is very close to the $0.649$ predicted by triality in quantum information.

1. Heh, stringers? And those people at CERN who keep reading my blog ... could you give me a job?

2. I'm fairly certain that Soni thinks that the anomaly in sin(2 beta) is due to a fourth generation of fermions.

3. Evil, as I mentioned in the previous post, I know that Soni is not thinking in terms of triality and quantum information. In his talk, he actually discusses something like Randall Sundrum. That does not mean that his analysis of the QCD estimates is incorrect.

4. Note that if we take the experimental error bars seriously, the best guess is $0.645$. It would be interesting to use this as a constraint on the CKM parameters that we started with.
