Scalar decays to , , and in the Georgi-Machacek model
Celine Degrande, Katy Hartling, Heather E. Logan
We compute the decay widths for the neutral and singly-charged Higgs bosons in the Georgi-Machacek model into the final states , , and . These decays are most phenomeno…
Automatic predictions in the Georgi-Machacek model at next-to-leading order accuracy
Celine Degrande, Katy Hartling, Heather E. Logan +2
We study the phenomenology of the Georgi-Machacek model at next-to-leading order (NLO) in QCD matched to parton shower, using a fully-automated tool chain based on MadGraph5_aMC@NL…
GMCALC: a calculator for the Georgi-Machacek model
Katy Hartling, Kunal Kumar, Heather E. Logan
The Georgi-Machacek model adds scalar triplets to the Standard Model Higgs sector in such a way as to preserve custodial SU(2) symmetry in the scalar potential. This allows the tri…
Indirect constraints on the Georgi-Machacek model and implications for Higgs couplings
Katy Hartling, Kunal Kumar, Heather E. Logan
We update the indirect constraints on the Georgi-Machacek model from -physics and electroweak precision observables, including new constraints from and $B^0_s \to μ^…
The decoupling limit in the Georgi-Machacek model
Katy Hartling, Kunal Kumar, Heather E. Logan
We study the most general scalar potential of the Georgi-Machacek model, which adds isospin-triplet scalars to the Standard Model (SM) in a way that preserves custodial SU(2) symme…
Two viable large scalar multiplet models with a Z2 symmetry
Kevin Earl, Katy Hartling, Heather E. Logan +1
We study models in which the Higgs sector is extended by a single scalar electroweak multiplet Z with isospin T=5/2 (sextet) or 7/2 (octet) and the same hypercharge as the Standard…
