Particle search on a shoestring

When Aaron Chou heard about an experiment in Italy that suggested the existence of an exotic particle as a candidate for dark matter, he was intrigued enough to go looking for it. His first stop: the Fermilab cafeteria.

What, no popcorn?

Though scientists are skeptical of the suggested particle's existence, the results from Legnaro need to be checked, says Chou, who strayed from his usual area of research–cosmology– to help put the project together. "It's unlikely but not impossible.
