Description
Since glueballs are SU(3)Flavor singlets, they should couple equally to u, d, and s quarks, so that equal coupling strengths to π+π- and K+K- are expected. However, we show that chiral symmetry implies the scalar-glueball amplitude for G0→qq is proportional to the quark mass, so that mixing with ss mesons is enhanced and decays to K+K- are favored over π+π-. Together with evidence from lattice calculations and experiment, this supports the hypothesis that f0(1710) is the ground state scalar glueball
