Researchers found that if Higgs particle collisions are required to always produce maximally entangled states, the Higgs potential automatically extends its global symmetry. This leads to an exact symmetry U(2)×U(2), spontaneously broken to U(1)×U(1), giving rise to six massless Goldstone bosons. A
