We’re thrilled to announce that the first results from Fermilab’s Muon g-2 experiment strengthen evidence of new physics! #gminus2
The Muon g-2 experiment at Fermilab sees fundamental particles called muons behaving in a way not predicted by the Standard Model of particle physics. These results confirm an earlier experiment performed at @BrookhavenLab. #gminus2
The combined results from Fermilab and Brookhaven show a difference with theory at a significance of 4.2 sigma. The chance that the results are a statistical fluctuation is about 1 in 40,000. #gminus2
The strong evidence that muons deviate from the Standard Model calculation might hint at exciting new physics. Muons act as a window into the subatomic world and could be interacting with yet undiscovered particles or forces. #gminus2
Want to learn more about today’s landmark result announced by the Muon g-2 collaboration? You can tune in to the scientific seminar happening now:
Physics fans, we are overwhelmed by your excitement. You're breaking all of our pages and streams like they're the Standard Model! We're working on it - thanks for your patience. The talk is also being recorded and will be available if you can't get to it right now. #gminus2
In its first year of operation, in 2018, the Fermilab #gminus2 experiment collected more data than all prior muon g-factor experiments combined. The first experimental run collected and analyzed more than 8 billion muons.
And there’s more data to come! Data analysis on the second and third runs of the experiment is under way, the fourth run is ongoing, and a fifth run is planned. #gminus2
Today’s result is an amazing achievement. Both the theoretical and experimental efforts required tremendous collaboration, brain power, and years of hard work. #gminus2
Want to be at the moment of the Muon g-2 unblinding? This video breaking down the new results features the moment researchers first revealed their data. #gminus2
An enormous congratulations to all the Muon g-2 collaborators on this incredible result! #gminus2
A reminder for journalists interested in this new Muon #gminus2 result: There will be a press conference at noon US Central today. Please contact media@fnal.gov for connection info.
Want to read more about the results? The Muon g-2 collaboration has published their results in PRL: #gminus2 journals.aps.org/prl/abstract/1…
And if today's scientific seminar was a lot to take in, mark your calendars to join us for a free virtual public lecture all about the Muon g-2 results on April 17: events.fnal.gov/arts-lecture-s…
Starting shortly: Press conference on the new Muon g-2 results! Watch live:
Thanks to everyone who tuned in to today’s Muon g-2 announcement! You can find the recordings of the press conference, scientific seminar, and results overview on Fermilab’s YouTube channel: youtube.com/c/fermilab/vid…
If you haven't yet taken yourself on a 360-degree tour of the Muon #gminus2 experiment, take a minute to experience the impressive experimental setup behind today's big result: 360.fnal.gov/vr/muong2/muon…

We're less than 24 hours away from learning the first results from the Muon g-2 experiment at Fermilab! #gminus2
Refresh your Muon g-2 knowledge before tomorrow's results seminar at 10am Central! Here's what Muon #gminus2 is looking for:
Muon g-2 is a blinded experiment. That means it used a secret code to obscure the result from the collaborators until the moment of unblinding. Here's how it works:
