---++ Recent publications including benchmark points and signatures

   * H. Abouabid et al., `Benchmarking Di-Higgs Production in Various Extended Higgs Sector Models',  https://arxiv.org/pdf/2112.12515.pdf
   * The above benchmark lines and benchmark planes in the bbbb, bbtautau, bbgamgam, tautaugamgam channels and more are published in U. Ellwanger et al., `Benchmark Planes for Higgs-to-Higgs Decays in the NMSSM', https://arxiv.org/pdf/2203.05049.pdf.

---++ Analyses that are using these benchmarks

Additional benchmark points for the tautaubb channel were also provided to enable a 2D exclusion region to be drawn for the CMS tautaubb analysis (https://arxiv.org/pdf/2106.10361.pdf). These benchmark points as well as a description of the procedure used to determine the 2D region can be found in NMSSMBenchmarksMarch2020tautaubbExtra

---++ Post YR4 considerations

The discussion after the Yellow Report 4 has focused on two objectives:
   * Answer the following question: Is it possible to produce meaningful parameter space planes in a similar way as in the case of the very successful MSSM benchmarks?
   * Motivate signatures that are not searched for in the experiments by providing evidence through parameter space scans that there is phase space for which such signatures are accessible in terms of sensitivity.

There is on-going work regarding the search for MSSM-benchmark planes, however, it seems that such a task is very difficult to achieve and most probably a more meaningful/realistic target is the second objective.

With respect to the 2nd objective, there is past and ongoing work to produce evidence from parameter space scans about signatures that are covered and not covered by the experiments. For example, see this paper [[https://arxiv.org/abs/1408.1120][1408.1120]].  New benchmark lines for various final states for  H3->H2+H1 can be found in NMSSMBenchmarksPostYR4 and the attachments below.

----+ YR4 points

In the context of Yellow Report 4 the group has studied individual points in the NMSSM parameter space. All the points are
described in detail at NMSSMBenchmarkPoints.
