Quark matter’s connection with the Higgs: Heavy ion collisions delve deeper into the origin of (visible) mass (August 14, 2012) -- You may think you've heard everything you need to know about the origin of mass. After all, scientists colliding protons at the Large Hadron Collider (LHC) in Europe recently presented stunning evidence strongly suggesting the existence of a long-sought particle called the Higgs boson, thought to "impart mass to matter." But while the Higgs particle may be responsible for the mass of fundamental particles such as quarks, quarks alone can't account for the mass of most of the visible matter in the universe -- that's everything we see and sense around us. ... > full story
