Muon Anomalous Magnetic Moment , Two - Higgs - Doublet Model , and Supersymmetry

The recent measurement of the muon anomalous magnetic moment aμ shows a 2.6σ deviation from the standard model value. We show that it puts strong constraints on the parameter space of the two-Higgs doublet model (2HDM) II. The dominant contribution of the Higgs bosons comes at the two-loop level, and in order to explain the data it favors a pseudoscalar A with a light mass range and a large tan...

2HDMC – a two Higgs Doublet Model Calculator

We present the program 2HDMC and how it can be used to explore the physics of general CP-conserving two Higgs doublet models. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.

The Electric Dipole Moment of the Muon in a Two Higgs Doublet Model

The electric dipole moment of the muon (dμ) is evaluated in a two Higgs doublet model with a softly broken discrete symmetry. The leading contributions from both one loop and two loop diagrams are considered. For tan β ≡ |v2|/|v1| close to one, contributions from two loop diagrams involving the t quark and the W boson dominate; while for tan β ∼ 10, contributions from two loop diagrams involvin...

Higgs-mediated muon-electron conversion process in supersymmetric seesaw model

We study the effect of the Higgs-exchange diagram for the lepton flavor violating muon-electron conversion process in nuclei in the supersymmetric seesaw model. The contribution is significant for a large value of tanβ and a small value of a neutral heavy Higgs boson mass, in which case the ratio of the branching ratios of B(μN → eN)/B(μ → eγ) is enhanced. We also show that the target atom depe...
