Georgi-Machacek Model

Extended Scalars Group Coordinators

Xiaohu Sun (ATLAS), Raffaele Gerosa (CMS), Heather Logan, Rui Santos, Oscar Stal, Shufang Su (theory)

Available Tools

• VBF@NNLO (M. Zaro et al.) Cross sections for VBF production of h, H, H50, H5+/-, H5++/--.
• GMCALC (H. Logan et al.) Spectrum calculator. Includes a routine to generate a param_card.dat file for use with the UFO file included in the FeynRules implementation.
• FeynRules implementation (K. Kunal et al.)

Available Results

• LHCHXSWG-2015-001 (CDS record), "Recommendations for the interpretation of LHC searches for H50, H5+/-, and H5++/-- in vector boson fusion with decays to vector boson pairs" (H.E. Logan and M. Zaro). Cross sections for VBF production of H50, H5+, H5-, H5++, and H5-- (NNLO QCD) at 8 and 13 TeV and decay widths to two vector bosons (tree level) for masses between 200 GeV and 2 TeV.

Benchmarks
