New Physics at D0
It boggles the mind how few people find this interesting. Anyway, as reported in the new physics paper of D0 (those are real physicists), in equation $(A26)$ we see that the Standard Model estimate for $\beta_s$ is $0.019 \pm 0.001$, which is in exact agreement with my fit for the $R(a)R(b)R(c)$ form. The reported new physics, which is currently at $3.2 \sigma$, must bring further CP violation into $B$ physics through a mechanism beyond basic information mixing. However, since the Standard Model cannot possibly account for this observation, one cannot help but conclude that the information mixing result is the correct place from which to investigate possible extensions to the $R(a)R(b)R(c)$ form.

To be precise: the fit with $(24,25/108,0.0035)$ gives $\beta_s = 0.0194$. This cannot be adjusted much without ruining the CKM entries.
ReplyDeleteFrom the real part of the $(ts)$ term, we see that the $0.0194$ basically comes from $abc$. That is, $\beta_s$ is just the product of our three parameters.

ReplyDeleteHave you mentioned it at phenomenology blogs? The mixing matrices are a complicated topic. The people most likely to take an interest are the ones already working with these quantities.
Mitchell, all physicists should be interested in these quantities, and what I am talking about is not at all complicated. Anyway, what blogs are you thinking of?
ReplyDeleteI don't know, I've never looked for them before. But e.g. see the "experimenter blogs" here.
ReplyDeleteAnd it is a complicated topic. If you say you're approximating a matrix with other matrices of a specified form, that's simple. But the physical significance of those matrix elements is not simple. It involves kaon decay and CP violation and other rather complex phenomena.
Also, your conceptual framework is unfamiliar. At least in F theory we know what it's all based on - the type IIB superstring. You can go to a textbook and see the basic equations behind all those branes in hyperspace.
Mitchell, the concept of CP violation can be explained to a child, and the particle zoo is built from a few simple building blocks. What is complicated, I think you will agree, is the Standard Model. But the SM never explained these parameters, and it never will.
ReplyDeleteAs for the fact that there are as yet no textbooks on categorical twistorial quantum gravity ... that is regrettable, indeed, but I am no position at present to do anything about it.
I hadn't realized that twistors are part of the plan! That helps a lot.
