Natural Higgs-flavor-democracy solution of the mu problem of supersymmetry and the QCD axion [PDF]
Jihn E. KimWe show that the hierarchically small mu term in supersymmetric theories is a consequence of two identical pairs of Higgs doublets taking a democratic form for their mass matrix. We briefly discuss the discrete symmetry S2xS2 toward the democratic mass matrix. Then, we show that there results an approximate Peccei-Quinn symmetry and hence the value mu is related to the axion decay constant.View original: http://arxiv.org/abs/1303.1822
