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 ...

If the dark matter particle's mass is less than the proton mass minus the pion mass, then the proton decay could be much faster than laboratory experiments imply, such as the limit from the Super ...

But newly released evidence contradicts his story. According to Pion's arrest warrant, a Florida Department of Transportation worker reviewed traffic camera footage from that morning and saw a man ...
