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…
Higgs Working Group Report of the Snowmass 2013 Community Planning Study
S. Dawson, A. Gritsan, H. Logan +131
This report summarizes the work of the Energy Frontier Higgs Boson working group of the 2013 Community Summer Study (Snowmass). We identify the key elements of a precision Higgs ph…
Learning what the Higgs boson is mixed with
Ryan Killick, Kunal Kumar, Heather E. Logan
The Standard Model Higgs boson may be mixed with another scalar that does not couple to fermions. The electroweak quantum numbers of such an additional scalar can be determined by…
Can the 126 GeV boson be a pseudoscalar?
Baradhwaj Coleppa, Kunal Kumar, Heather E. Logan
We test the possibility that the newly-discovered 126 GeV boson is a pseudoscalar by examining the correlations among the loop-induced pseudoscalar decay branching fractions to $γγ…
