Particle Oddball Surprises Physicists

Scientists at Fermilab announced that they have found evidence of an unexpected particle whose curious characteristics may reveal new ways that quarks can combine to form matter. The physicists have called the particle Y(4140), and  it appears to flout nature’s known rules for fitting quarks and antiquarks together.

"It must be trying to tell us something,” said CDF cospokesperson Jacobo Konigsberg. 

“So far, we’re not sure what that is, but rest assured we’ll keep on listening.”
