…non-CCQE events). A CCQE-like event is one that has at least one outgoing muon, any number of protons or neutrons, and no mesons as final-state particles. (Mesons, like protons and…
10 years later, Higgs boson discoverers publish refined measurements
…Run 2—30 times more than in 2012 (though they only analyze a fraction of that number). “The Higgs boson has only gotten ‘bigger’ [in the last decade],” says Fermilab CMS…
Dark Energy Spectroscopic Instrument (DESI) creates largest 3D map of the cosmos
…“Back when I started in astronomy, it would have taken years to collect the same number of redshifts that we now obtain in as little as 15 minutes,” said Stephen…
Muon g-2 experiment results: physicists may have discovered a new force of nature
From Inverse, Sept. 28, 2021: Suspect number one at the center of the particle-filled mystery? The humble muon. Scientists at CERN began studying the magnetism of muons in the 1950s,…
Berkeley Lab researchers record successful startup of LUX-ZEPLIN dark matter detector at Sanford Underground Research Facility
