all over the news in the science world what appears at a confidence level of 3.5 sigma are cillision results of CP violation at the LHCb
all the articles i've read advises caution as to the results.
the last article of several i read had this interesting observation"
"I’ll leave it to the trained philosophers in the audience to find the logical flaw in that argument. Try substituting “George Washington” and “cherry trees” for “CP violation” and “baryogenesis.”
The point is that the conclusion doesn’t hold — not everything about CP violation is necessarily related to baryogenesis. We don’t know how baryogenesis actually happened — there are many theories on the market, and any of them or none of them may be right. Therefore, there’s no way of knowing whether any particular manifestation of CP violation is in any way related to baryogenesis. There could be lots of different ways in which CP is violated. In particular, there’s no compelling theoretical reason why the CP violation being studied in the decays of B mesons has anything at all to do with baryogenesis. It’s possible — lots of things are possible. But what’s being studied isn’t baryogenesis; it’s CP violation.
So why isn’t that enough? The answer is obvious — explaining why we are here seems to be something that a wider audience can get excited by more directly than studying the details of a slightly-broken symmetry. The only problem is that it’s not true; these experiments aren’t really studying why we are here.
We can’t blame journalists for this one; here is a case where they are just reporting what the scientists tell them, and the scientists are quite willing to be shameless. I understand the motivation for being shameless — it’s hard to explain the details, and the results are legitimately interesting. But ultimately I don’t think it’s right to say untrue things in the name of getting people excited about true things.
I would therefore like to see particle physicists take a slightly more honest tack about the importance of CP violation. It’s perfectly okay to say that it gives us insight into the difference between matter and antimatter — that’s true. And that should be enough! It’s not okay to say that it gives us insight into the imbalance between matter and antimatter in our observable universe; it’s completely possible (even likely) that such a statement is simply false. If we get people excited about what we’re doing by causing them to misunderstand what that actually is, we’re ultimately not winning."
