TWIKI with additional information

Ongoing work

  • Check physics case for 3HDM, LRS, CPV, SM+Triplet models, in case provide cross sections and BRs: Santos to write short summary of which code is good for which
  • Interface theory constraints for an additional singlet into ScannerS: done. The latest version of ScannerS that include a large number of models with extended scalar sectors is now available, see https://arxiv.org/pdf/2007.02985.pdf. The code includes the usual theoretical constraints: stability and perturbativity and electroweak precision together with interfaces with several other codes. A description on how to check if a given point is allowed by the constraints can be done for the CxSM and is described in detail in the following presentation https://indico.cern.ch/event/640710/contributions/2599076/attachments/1463561/2261560/MSampaioWG3_20170522.pdf.
  • Cross sections and BRs for 2HDM+singlet models (real & complex): Nikos Rompotis.
  • Inclusion of 2HDM electroweak baryogenesis information in electroweak phase transition properties by using the BSMPT code by Maggie: Maggie, Nikos Rompotis.
  • Theoretical predictions for interference effects for large width charged Higgs decays: done. Santos to write a short description of regions of parameter space that have large interference effects.
  • Expand 2HDM/MSSM H+ cross sections from 2 two 3 TeV: contact.
  • Provide benchmark scenarios for searches for H5 states in GM for masses below 200GeV: Heather Logan
  • Provide simulation tool for loop-induced H+->W+ gamma with fermiophobic H+ in GM: Heather Logan
