---+++ Additional benchmark points for ggF-&gt;H3-&gt;(H_SM-&gt;tautau)+(H_singlet-&gt;bb)

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

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

%\[ ggF \ \   \longrightarrow   \ \ \ H_{MSSM}\ \ \  \longrightarrow  (H_{SM} \longrightarrow \tau\tau) \ \ + \ \  (H_{singlet} \longrightarrow bb)   \]% </br>
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 |
