"Measuring the spin-parity provides crucial insight into the internal quark dynamics and interaction mechanisms within the baryon," said Wan. They used sophisticated amplitude analysis techniques ...

“Spin correlation is a very powerful tool to look for new physics,” Grohsjean says. Scientists can precisely predict the ratio of top quark pairs with parallel spins (both spinning in the same ...

On March 2, 1995, the top quark discovery at Fermilab was announced by scientists on the CDF and DZero collaborations, and the sixth and final quark was added to the Standard Model. Thirty years ago, ...
