Search for New Quarks Highlighted by CERN and PRL

A search for a new type of quark performed by Dr. Haley and his colleagues on the ATLAS experiment at CERN has been highlighted by CERN and selected by PRL as an Editors' Suggestion.

This paper sets the world's tightest limits on these hypothetical particles (call "vector-like quarks") that some theorist believe may be the key to understanding the properties of the Higgs boson and the unification of the fundamental forces.
