Additional benchmark points for ggF->H3->(H_SM->tautau)+(H_singlet->bb)

The benchmark points correspond to the maximum cross-section times branching ratio
allowed in the NMSSM after experimental constraints from Higgs
boson measurements, searches for supersymmetry, B-meson physics and dark
matter detection as implemented in the used codes NMSSMTools 5.5.0 [1] and
NMSSMCALC [2].

These points are an extension to those provided in NMSSMBenchmarksMarch2020 for the process:

\[ ggF \ \   \longrightarrow   \ \ \ H_{MSSM}\ \ \  \longrightarrow  (H_{SM} \longrightarrow \tau\tau) \ \ + \ \  (H_{singlet} \longrightarrow bb)   \]

These points were used to produce the 2D exclusion region in the CMS publication [3] shown below:

The cross section values used to produce the contours are tabulated below:

MH3 MH_singlet max. Xsect [pb]
400 190 0.2870E-01
400 250 0.8118E-02
450 190 0.2278E-01
450 250 0.1722E-01
500 250 0.1217E-01
500 300 0.7850E-02
550 190 0.9352E-02
550 250 0.7609E-02
600 150 0.4257E-02
600 170 0.5056E-02

Linear interpolations of the 95%CL excluded cross-section*BR from [3] and of the max. allowed cross-section*BR from the previous table were then used to determine the boundary values of MHs. These boundary values are tabulated below:

MH3 Lower bound on MH_singlet
400 197
450 218
500 253
550 228
600 154
700 0
