LHC

From Science News, August 15, 2022: W bosons are particles that transmit the weak force, which is responsible for certain types of radioactive decay. Last April, Fermilab researchers reported the W boson was more massive than predicted, hinting that something may be amiss with the standard model. Now a team of scientists with ATLAS at the LHC are reporting rare boson triplets which continues to test the standard model for any cracks.

Scientists worried Higgs pairs would be too rare for LHC experiments to find. But by using machine learning, they now are getting tantalizingly close.
