The Muon Electric Dipole Moment
Abstract
The electric dipole moment of the muon (dμ) is evaluated in a two Higgs doublet model with a softly broken discrete symmetry. For tanβ ≡ |ν2|/|ν1| ~ 1, contributions from two loop diagrams involving the t quark and the W boson dominate; while for tan→ ≿ 10, contributions from two loop diagrams involving the b quark and the τ lepton are dominant. For 8≿ tanβ≿4, significant cancellation occurs among the contributions from two loop diagrams and the one loop contribution dominates for tanβ ~ 7. For tanβ ≿ 15, the calculated dμ can be close to the reach of a recently proposed experiment at the Brookhaven National Laboratory.
