The effects of non-universal extra dimensions on the fermion electric dipole moments in the two Higgs doublet model

Abstract

We study the the effects of non-universal extra dimensions on the electric dipole moments of fermions in the two Higgs doublet model. We observe that the t quark and b quark electric dipole moments are sensitive to the extra dimensions, however, in the case of charged lepton electric dipole moments, this sensitivity is relatively weak. *

The effects of lepton KK modes on the electric dipole moments of the leptons in the Randall–Sundrum scenario

“…The electron EDM has been predicted of the order of the magnitude of 10 −32 e − cm in the two Higgs doublet model (2HDM), including the tree level flavor changing neutral currents (FCNC) [7] and, in this case, the additional CP sources are new complex Yukawa couplings. The EDMs of fermions have been analyzed in [8] and [9], in the 2HDM with the inclusion of non-universal extra dimensions and in the framework of the split fermion scenario. The EDMs of quarks were calculated in the MHDMs, including the 2HDM in [10,11,12], the fermion EDMs in the SM, with the inclusion of non-commutative geometry, have been estimated in [13], the lepton EDMs have been studied in the seesaw model in [14], the EDMs of nuclei, deutron, neutron and some atoms have been predicted extensively in [15], limits on the dipole moments of leptons have been analyzed in a left-right symmetric model and in E 6 superstring models in [16].…”

Electric dipole moments of charged leptons in the split fermion scenario in the two Higgs doublet model

“…The quark EDMs have been estimated in several models [6] and the EDMs of nuclei, deutron, neutron and some atoms have been studied extensively [7]. The lepton electric dipole moments have been predicted in various studies [8]- [11]. In [8] the lepton electric dipole moments has been analyzed in the framework of the seesaw model.…”
