slide 3: The Higgs sector in the MSSM with its two Higgs doublets - which 
         give rise to five physical Higgs bosons with masses that are no
         free parameters in general - is described. The mass of the lightest
         Higgs boson has an upper theoretical mass bound.

slide 4: For the determination of the Higgs masses, the zeros of the 
         determinant of the two-point function Gamma is calculated.

slide 5: The biggest part of the determination of the two-point function 
         is the calculation of the Higgs self energies. On this slide, the 
         contributions to the Higgs self energies implemented in FeynHiggs 
         are listed.

slide 6: On this slide, the complex parameters beyond the Standard Model 
         ones are listed. Mostly, the complex parameters are soft 
         supersymmetry breaking parameters except for the parameter mu and 
         the phase between the Higgs doublets. At tree-level, there are no
         CP-violating phases in the Higgs sector.

                            one-loop contributions as a function of the 
                            phase of the squark mixing parameter X_t,
                                  X_t = A_t - mu^* cot(beta),
                            for small and large mass of the charged Higgs boson.

                            one-loop contributions and two-loop 
                            contributions of the order O(alpha_t alpha_s) 
                            as a function of the phase of the squark mixing 
                            parameter X_t for small and large mass of the 
                            charged Higgs boson.

                            dependence of the mass of the lightest Higgs 
                            boson when going from one- to two-loop order

slide 10: FeynHiggs results: Mass of the lightest Higgs boson including
                             one-loop contributions and two-loop
                             contributions of the order O(alpha_t alpha_s)
                             as a function of the phase of the squark mixing 
                             parameter X_t for small and large mass of the
                             charged Higgs boson; in addition, there is a 
                             band showing the size of the corrections of 
                             O(alpha_t^2 + alpha_b alpha_s 
                               + alpha_b alpha_{t,b}).
                             The boundaries of the band are given by 
                                M_{h_1}^{boundary} (phi_Xt) 
                                   = M_{h_1}^corrected (phi_Xt) 
                                     + Delta M_{h_1}(phi_Xt = 0)
                              and
                                M_{h_1}^{boundary} (phi_Xt)  
                                   = M_{h_1}^corrected (phi_Xt) 
                                     + Delta M_{h_1}(phi_Xt = pi),
                              respectively. Delta M_{h_1} gives the size of the
                              contributions that are only known for real 
                              parameters, namely the corrections of O(alpha_t^2
                              + alpha_b alpha_s + alpha_b alpha_{t,b}).

slide 11:  FeynHiggs results: see slide 10 + an interpolation of the 
                              contributions that are only known for real 
                              parameters, namely the corrections of O(alpha_t^2
                              + alpha_b alpha_s + alpha_b alpha_{t,b}).

slide 12: There, an (incomplete) comparison of the features of the two 
          programs "FeynHiggs" and "CPsuperH" is shown. Especially, the 
          different schemes used for the input parameters is emphasised.

slide 13: For the comparison of the results of "FeynHiggs" and "CPsuperH" 
          the parameters have to be transformed from one scheme to the other.

slide 14: Results of the comparison of "FeynHiggs" and "CPsuperH":
          The Higgs mass is shown as a function of the phase of the 
          parameter A_t in the DRbar scheme. On this slide, only 
          corrections up to O(alpha_t alpha_s) are included into the 
          "FeynHiggs" result. The squark parameter transformation includes 
          only terms of O(apha_s).

slide 15: With respect to slide 14, the "FeynHiggs" result including the 
          interpolation of the corrections of O(alpha_t^2 + alpha_b alpha_s 
          + alpha_b alpha_{t,b}) are added into the plot. The 
          squark parameter transformation includes only terms of O(apha_s).

slide 16: With respect to slide 14 and slide 15, "FeynHiggs" results 
          are added that have been obtained using squark parameters 
          determined via a squark parameter transformation that includes not 
          only terms of O(apha_s) but also of O(apha_t).

slide 17: With respect to slide 14, slide 15 and slide 16, "FeynHiggs" 
          results are added taking into account the O(apha_t) 
          transformation of the parameter mu.

slide 18: Results of the comparison of "FeynHiggs" and "CPsuperH": 
          The Higgs mass is shown as a function of the absolute value of 
          the parameter A_t in the DRbar scheme. On this slide, only
          corrections up to O(alpha_t alpha_s) are included into the
          "FeynHiggs" result. The squark parameter transformation includes
          terms of O(apha_s + alpha_t).

slide 19: With respect to slide 18, "FeynHiggs" results are added that 
          include the interpolation of the corrections of the O(alpha_t^2 
          + alpha_b alpha_s + alpha_b alpha_{t,b}).
