HH Cosmo Indirect

Europe/Stockholm

- Several people from Uppsala, Lund and Stockholm present.
- The discussions centered on possible benchmark points that could bring together LHC and GW observables and also make use of recent progress of the tools available. One proposed step forward could be to add colored scalars in the DRalgo tool. For FOPT it is known that NMSSM is a possible candidate (MSSM is essentially ruled out). A first attempt could be to see if we can find an NMSSM point with a 50% increase in the higgs self-coupling. This is a region where LHC has a chance to see it through the "effective approach" T=0 window and where studies have shown that FOPT can be induced by EFT effects alone. If such a benchmark point can be found we have a physical UV model to develop and test a complete chain of tools from and make the connection. Harri is the SUSY expert in the team and will have a go to see if such a point can be found. The next step would then be to match the required NMSSM lagrangian parameters manually to DRalgo.
- It was also suggested that a useful intermediate step (publication) could be to first look at PT results in the high temperature domain where we don't have to rely on integrating out the stops.
