In around 13 out of every 100 billion kaon decays, however, the result is an antineutrino, a neutrino, and an unstable particle made of another flavor of quark and an antiquark called a pion.

A new lattice QCD calculation connects two seemingly disparate reactions involving the pion, the lightest particle governed by the strong interaction. As an undergraduate student at Tecnológico ...
