We couldn't discover a particle of treachery hidden anywhere in his mind.

James Chadwick discovered a much more massive nuclear particle in 1932 and also named it a neutron, leaving two kinds of particles with the same name.

In 1974, using beams of electrons and antielectrons, or positrons, Dr. Richter discovered a particle that came to be called Psi/J.

In 2009, Fermilab announced that they have discovered a particle temporarily called Y(4140), which may also be a tetraquark.

In 2003 he discovered a new particle, dubbed D*(2317), unexpected resonance constituted by a charm quark and a strange quark.

Using a fixed-target experiment, the collaboration discovered a particle, which they called an upsilon.

With it he led a team that discovered a new subatomic particle he called a ψ (psi).

Then Chadwick devised an experiment that discovered a new, uncharged particle with roughly the same mass as the proton: the neutron.

Maybe we've discovered a really big particle, she thought crazily, the bigon.

The equipment necessary for discovering a subatomic particle in your own home costs too much and would never fit inside a basement laboratory or even a very large backyard.
