◆ delta_mh2_1loop()

RM22 himalaya::mh2_fo::MSSM_mass_eigenstates::delta_mh2_1loop ( double p2 ) const

Higgs 1-loop contribution DR'.

Higgs 1-loop DR' contribution for arbitrary momentum. The function returns 1/(4Pi)^2 (-selfenergy + tadpole).

Parameters

p2	squared momentum

Returns: 1-loop contribution

Definition at line 199 of file MSSM_mass_eigenstates.cpp.

◆ delta_mh2_1loop_gaugeless()

RM22 himalaya::mh2_fo::MSSM_mass_eigenstates::delta_mh2_1loop_gaugeless ( ) const

Higgs 1-loop contribution DR' for p = g1 = g2 = 0.

Higgs 1-loop DR' contribution in the gaugeless limit (p = g1 = g2 = 0). Note, that p = 0 in the gaugeless limit, because in the MSSM p = mh = 0 vanishes when g1 = g2 = 0.

The function returns 1/(4Pi)^2 (-selfenergy + tadpole).

Returns: 1-loop contribution for p = g1 = g2 = 0

Definition at line 340 of file MSSM_mass_eigenstates.cpp.

◆ delta_mh2_1loop_gaugeless_deriv()

RM22 himalaya::mh2_fo::MSSM_mass_eigenstates::delta_mh2_1loop_gaugeless_deriv ( ) const

derivative of Higgs 1-loop contribution DR' for p = g1 = g2 = 0

Derivative of Higgs 1-loop DR' contribution w.r.t. p^2, in the gaugeless limit (p = g1 = g2 = 0). Note, that p = 0 in the gaugeless limit, because in the MSSM p = mh = 0 vanishes when g1 = g2 = 0.

The function returns 1/(4Pi)^2 d/dp^2 (-selfenergy + tadpole).

Returns: derivative of 1-loop contribution for p = g1 = g2 = 0

Definition at line 424 of file MSSM_mass_eigenstates.cpp.

◆ delta_mh2_2loop()

RM22 himalaya::mh2_fo::MSSM_mass_eigenstates::delta_mh2_2loop ( ) const

Higgs 2-loop contributions DR' for p = 0.

CP-even Higgs 2-loop DR' contribution in the gaugeless limit (p = g1 = g2 = 0).

Note: The 2-loop contribution to the heavy CP-even Higgs mass assumes that the tree-level CP-even Higgs mass matrix is expressed in terms of the CP-odd Higgs pole mass, see [hep-ph/0105096] Eqs.(22)-(23). If the tree-level CP-even Higgs mass matrix is expressed in terms of the running CP-odd Higgs mass, then a corresponding 2-loop contribution to the CP-odd Higgs mass must be included in this function. See the implementation in SOFTSUSY/FlexibleSUSY for an example.

Returns: 2-loop contribution for p = g1 = g2 = 0

Definition at line 502 of file MSSM_mass_eigenstates.cpp.
