Congrats to the authors, I cannot stress how annoying this process is to measure
The production of top quark pairs together with a W boson is a great way to test the quality of standard model predictions. This #CMSPaper measures provides boundaries on things like the difference between ttW+/- production, a very sensitive quantity to test the predictions arxiv.org/abs/2509.13512

China *will* consider the Super Tau-Charm Factory though?
If the Hamiltonian flow of everyone in your neighborhood has brought them to bigotry, well...
"The cultivated mind is the guardian genius of democracy" is a quote that pretty clearly terrifies certain people
Ironically "university students are rowdy, don't come out with the proper opinions, and their faculty discuss impractical nonsense" is one of the constants of the Western Civilization these folks claim to love so much. McArdle would collapse in shock at 1200s Paris
The thing about her list of complaints about academia (protests! chronicling Western oppression! research with no practical benefit! the CDC for some reason!) is that they can only be addressed by reducing the scope of things people do in universities, which doesn't sound like "viewpoint diversity"
The definition of “viewpoint diversity” that figures like this promote implies *censorship* (the “must” part): curbing some forms of expression to boost others. It’s an invention of orgs who advocate government censorship of teaching/research + restrictions on protected political speech in colleges.
Finally, a proper James Bond villain plan

Aside from "political" issues, I'm genuinely convinced that administrators like this are also flat out just not going to be good at running complex organizations, where success for the entity (as opposed to the individual) requires a deft political touch, not Executive Brain
I'm always vaguely astonished at how cartoonish these people wind up being. If the school leadership is so certain it's doing the right thing, why the fear of student journalists?
Indiana University has fired the staff director of the student newspaper, after disputes in which university leadership tried to pressure him to prevent students from publishing news.
Clearly he should be on the end of corners, not serving them
Thank you, see you next year #AustinFC

From 2023:
"People who lack experience, do not care about core organizational goals, will not listen to stakeholders, and are hell-bent on pursuing their narrow ideological agenda will ultimately destroy the organizations they are charged with leading."

Of course it's entirely possible they want to ban giving any preferences to veterans since that is correlated with race and gender
SPEAKING FOR MYSELF (because apparently it needs to be said) the regents and administration might want to ask themselves if this is really a precedent they want to set

It's always fascinating which things are assumed to be common knowledge in different eras. "... the well-known result that the phase of the wave function corresponds to Hamilton's principle [sic] function in classical theory" oh is it well known?
Yeah I read theory
