UW–Madison physicists with the #NOvA collaboration led a new study in PRL that "sets some of the strongest limits on the existence of the sterile #neutrinos," according to lead author Adam Lister. @fermilab.bsky.social www.physics.wisc.edu/2025/02/26/n... #physics #HighEnergyPhysics

To be entirely honest it might be irresponsible at this point to host general US HEP meetings at Fermilab

I fear I'm going to turn into one of those weirdos who obsesses with Dirac equation solutions but... is there something to learn from the fact that a moving particle can only be a spin eigenstate along its direction of motion?

I do have colleagues who think particle physics is immune to culture war issues and hoo boy let me assure you that it is not

Just got the dreaded email. University of Iowa is halting all NIH grant submissions. Losing a generation of scientists here will send the state backwards. What a travesty.

Because it's kind of hidden in the thread: dear academics, please actually look at your institution's budget before you say "oh maybe we can just get rid of admin with no other effects"

Some notes on indirect costs at US universities, since people might be curious (Note: I am not an expert and only really have experience with UT. You may find budget.utexas.edu/about/budget interesting)

So why is it that people implicitly link the Klein-Gordon equation with a scalar field? Dirac fermions also satisfy it...

Going to be the annoying guy and say that I honestly haven't seen any step function in student ability that I would attribute to online learning during COVID per se

Flew into National tonight. Could see from the air that Gravelly Point was blocked off and... yeah, it was a bit overwhelming.

I'm not sure I've encountered a textbook figure so subtly but incredibly misleading as 3.3 in Thomson's Modern Particle Physics

The exciting thing is how the exact same outreach efforts are "DEI" or not depending on which zip code they're done in
