Remarks regarding the 2-Higgs-Doublet-Model (2HDM)

Our implementation of the 2-Higgs-Doublet-Model (2HDM) follows the review:

Theory and phenomenology of two-Higgs-doublet models
G. C. Branco, P. M. Ferreira, L. Lavoura, M. N. Rebelo, Marc Sher, Joao P. Silva

The three neutral Higgs bosons h, H (CP-even) and A (CP-odd) are characterized
by their masses (independent input parameters), the ratio of the vacuum
expectation values tan(β) and the CP-even Higgs mixing angle α.

The four 2HDM types differ by the Higgs coupling to the SM fermions f.
The relative strengths g_f^{h,H,A} of the Higgs-quark couplings
with respect to the SM strengths are given by:
(The leptonic couplings are not relevant within SusHi).
Due to consistency with 2HDMC we interchanged types 3 and 4 in SusHi 1.4.1!
If you use older versions of SusHi and link to 2HDMC, please ignore types 3 and 4.

Relative strength 1 = Type I 2 = Type II 3 = Flipped 4 = Lepton-specific
g_u^h cos(α)/sin(β) cos(α)/sin(β) cos(α)/sin(β) cos(α)/sin(β)
g_d^h cos(α)/sin(β) -sin(α)/cos(β) -sin(α)/cos(β) cos(α)/sin(β)
g_u^H sin(α)/sin(β) sin(α)/sin(β) sin(α)/sin(β) sin(α)/sin(β)
g_d^H sin(α)/sin(β) cos(α)/cos(β) cos(α)/cos(β) sin(α)/sin(β)
g_u^A 1/tan(β) 1/tan(β) 1/tan(β) 1/tan(β)
g_d^A -1/tan(β) tan(β) tan(β) -1/tan(β)

Please find an example input and output file in the folder "/example"
within the SusHi main directory.
Similar to the MSSM we recommend the usage of the electroweak contributions by
light quarks for gluon fusion cross sections.
