Real singlet scalar dark matter extension of the Georgi-Machacek model
Robyn Campbell, Stephen Godfrey, Heather E. Logan +1
The Georgi-Machacek model extends the Standard Model Higgs sector with the addition of isospin-triplet scalar fields in such a way as to preserve the custodial symmetry. The presen…
Large scalar multiplet dark matter in the high-mass region
Heather E. Logan, Terry Pilkington
We study two models of scalar dark matter from "large" electroweak multiplets with isospin 5/2 (n=6 members) and 7/2 (n=8), whose scalar potentials preserve a symmetry. Becau…
Implications of a Electroweak Triplet Scalar Leptoquark on the Ultra-High Energy Neutrino Events at IceCube
Nicolas Mileo, Alejandro de la Puente, Alejandro Szynkman
We study the production of scalar leptoquarks at IceCube, in particular, a particle transforming as a triplet under the weak interaction. The existence of electroweak-triplet scala…
and Meson Spectroscopy
Stephen Godfrey, Kenneth Moats, Eric S. Swanson
Properties of bottom and bottom-strange mesons are computed in two relativized quark models. Model masses and wavefunctions are used to predict radiative transition rates and the $…
Golden Probe of Electroweak Symmetry Breaking
Yi Chen, Joe Lykken, Maria Spiropulu +2
The ratio of the Higgs couplings to and pairs, , is a fundamental parameter in electroweak symmetry breaking as well as a measure of the (approximate) custodial s…
The Dilaton-like Higgs boson with scalar singlet dark matter
Robyn Campbell, Stephen Godfrey, Alejandro de la Puente
We study a model with a Higgs-like dilaton and a Standard Model gauge-singlet scalar dark matter candidate. We begin by updating the status of identifying the observed 125 GeV Higg…
