EDMs in the Two Higgs Doublet Model
PRD89 (2014) 115023
Present constraints on the CP-violating phase and tan beta in the 2HDM having a softly-broken Z2 symmetry. Excluded regions from the present limits on the electron (light blue), neutron (light green), and 199Hg atom (red) EDMs are indicated, along with a theoretically inaccessible region (purple).
Full analysis and figures, including impact of prospective future limits and hadronic and nuclear theory uncertainties, can be found in ArXiv and journal references listed above.
Current and prospective future constraints from electron EDM (blue), neutron EDM (green), mercury EDM
(red), and radium (yellow) in flavor conserving 2HDMs in the Type II model. Left panel gives present constraints. Middle panel gives combined future limits if the mercury and neutron EDMs are both improved by one order of magnitude. Blue dashed curves indicate future constraints if electron EDM is be improved by another order of magnitude. Right panel shows prospective future limits if the mercury and neutron EDMs are improved by 1 and 2 orders of magnitude, respectively
Present constraints implied by neutron EDM bounds for various choices of the hadronic matrix elements for the type II 2HDM. Solid line corresponds to the choosing the central values in Table 7 of Engel, Ramsey-Musolf, and van Kolck, Prog. Part. Nucl. Phys. 71 (2013) 21-74, arXiv:1303.2371. Dashed and dot-dashed curves correspond to varying the matrix elements over the ranges given in that table.
Present constraints implied by mercury EDM bounds for various choices of the nuclear Schiff moment sensitivity coefficients for the type II 2HDM. Solid line corresponds to the choosing the central values in Table 13 of Engel, Ramsey-Musolf, and van Kolck, Prog. Part. Nucl. Phys. 71 (2013) 21-74, arXiv:1303.2371. Dashed and dot-dashed curves correspond to varying the matrix elements over the ranges given that table: a0 = 0.01, a1 = 0.02 (solid, central value), a0 = 0.01, a1 = 0.09 (long dashed), a0 = 0.01, a1 = -0.03 a0 ¼ 0.01 (dashed), a0 = 0.005, a1 = 0.02 (dotted), and a0 = 0.05, a1 = 0.02 (dot dashed).
