TWIKI with additional information

• Twiki containing BRs numbers for H+->cb in the 3HDM: Hplus3HDM.
• Twiki containing cross section and BRs numbers for 2HDM: LHCHWG2HDM ("2HDM Ntuple")
• Twiki containing cross section and BRs numbers for flavorful 2HDM: LHCHWG3Flavorful2HDM.
• Twiki for LFV Higgs decay in BGL.
• Twiki for 2HDM benchmarks.
• Twiki for the Georgi-Machacek model.
• Twiki for benchmarks other than 2HDM
• Twiki for the width and interference treatment recommended for a common treatment for ATLAS and CMS analyses.
• Twiki for MSSM charged Higgs (heavy, light, intermediate masses).

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
