D-brane instanton induced mu-terms and their hierarchical structure
arXiv:1502.03582 · doi:10.1103/PhysRevD.92.026001
Abstract
We study the mu-term matrix of Higgs pairs induced by the D-brane instanton effects in intersecting D6-brane models compactified on T6. It is found that the mu-term matrix has a certain permutation symmetry and its eigenvalues have large hierarchical structure without fine tuning.
