A new lattice QCD calculation connects two seemingly disparate reactions involving the pion, the lightest particle governed by the strong interaction.

A team of theoretical high-energy physicists has published a new high-precision calculation that could significantly advance the indirect search for physics beyond the Standard Model. The ...

For 15 years, there has been a mismatch in physics. A particle called the muon wasn’t behaving the way theory predicted it should. A new theory and new experiment might solve this problem.
