Quarks in the looking glass

A recent experiment has determined how much of the mirror-symmetry breaking in the electron-quark interaction originates from quarks' spin preference in the weak interaction five times more precisely than a previous measurement. The result has also set new limits, in a way complementary to high-energy colliders such as the Large Hadron Collider at CERN, for the energies that researchers would need to access physics beyond the Standard Model.http://feeds.sciencedaily.com/~r/sciencedaily/~3/w...
