The results of the Muon g-2 experiment for the anomalous mag. moment of the muon, showing the Brookhaven National Laboratory result and the final experimental average.
New and final Muon g-2 experimental result for the anomalous magnetic moment of the muon @fermilab.bsky.social:
aµ(exp-avg) = 116 592 0715(145) × 1e−12 (124 ppb)
We are now seeing results quoted with a 10^-12 exponent instead of 10^-11. Clear progress!

New course this Fall @ the University of Iowa. Should be a lot of fun!

We have extended the deadline to apply for the 2025 edition of the International Neutrino Summer School!
INSS 2025 @ Fermilab August 11-22 2025
The International Neutrino Summer School (INSS) 2025 will be held at Fermilab from Aug 11 - 22.
Please share with interested graduate students! We are building a great line-up of lecturers this year.

That's fantastic, congratulations!

Almost 5 years in the making, here's the first search for dark sectors with e+e- at MicroBooNE!
14.02.2025 22:03 — 👍 4 🔁 0 💬 2 📌 0This is a very exciting development for our field 🧪⚛️
The energy of this neutrino event is so high that the COM energy of the collision is close to LHC energies!
It would not have been visible if it didn't come from close to the horizon. The Earth is opaque to it.
Congrats @km3net.bsky.social!
📢KM3NET DETECTS THE HIGHEST ENERGY NEUTRINO EVER OBSERVED
This #KM3NeT_UHE event KM3-230213A is estimated to have a record neutrino energy of 220 PeV, or 220 million billion electronvolts

15% is a subpar tip these days.
Science and universities deserve better.
We had a great Theory-Experiment Joint Seminar at Fermilab yesterday by MicroBooNE.
Their new results on neutrino production of single photons are all here: microboone.fnal.gov/single-photo....
The MiniBooNE saga continues, but this feels like a good step forward.
Isn't that the best though? I love it.

23.01.2025 03:24 — 👍 1 🔁 0 💬 0 📌 0Organized Skepticism:
scientific claims should be exposed to critical scrutiny before being accepted: both in methodology and institutional codes of conduct.
Disinterestedness:
scientific institutions act for the benefit of a common scientific enterprise, rather than for specific outcomes or the resulting personal gain of individuals within them.
Universalism:
scientific validity is independent of the sociopolitical status/personal attributes of its participants.
Communism:
all scientists should have common ownership of scientific goods (intellectual property), to promote collective collaboration; secrecy is the opposite of this norm.
⚛️🧪 At my Responsible Conduct in Research training I learned about the Mertonian norms of science (en.wikipedia.org/wiki/Mertoni...).
It is funny how big science and competition has produced an environment that so often goes directly against these.
I just learned that Elsevier, the publishing company, has had a year over year profit margin between 30-40% for the past decade.
That's more than most big tech companies like Google and Microsoft.
Think about that next time you hit a paywall.
Fun!

Top) two muon collider ring designs indicating where muons decay. Bottom) two views of the detector and the region where neutrinos interact dubbed the "neutrino slice".
New paper and one more reason why muon colliders are such unique machines.

Imagine if @atlasexperiment.bsky.social and @cmsexperiment.bsky.social were popping with neutrino interactions at a rate of kilohertz!
This was a lot of fun and was led by Luc, an UG at Harvard!
This is a very nice read and I'm glad for the click bait abstract.
