### CKM and New Physics

The reviewer who said there was nothing new in the mixing matrix paper would be advised to watch this seminar by Amarjit Soni. It discusses the likelihood that $\textrm{sin} 2 \beta$ takes a non Standard Model value ... namely very likely. Soni appears to be unaware that a numerical prediction for $\textrm{sin} 2 \beta$ exists and is consistent with experimental bounds. The talk is enjoyable also for the audience participation.

1. The paper is here.

2. If CPT is violated in the neutrinos, it would be a little bit too much for theories of CP violation to be perfect in the quarks.

I'm still trying to get my head around the concept of CPT violation (i.e. how to do the calculations) and I've not made much progress.
