kaon

Nearly 75 years after the puzzling first detection of the kaon, scientists are still looking to the particle for hints of physics beyond their current understanding.

From Brookhaven National Laboratory, Sept. 17, 2020: Brookhaven theorists publish an improved prediction for the tiny difference in kaon decays observed by experiments. Understanding these decays and comparing the prediction with more recent state-of-the-art experimental measurements made at Fermilab and CERN gives scientists a way to test for tiny differences between matter and antimatter.
