Multi-TeV Signals of Baryogenesis in Higgs Troika Model
Hooman Davoudiasl, Ian M. Lewis, Matthew Sullivan
A modest extension of the Standard Model by two additional Higgs doublets - the Higgs Troika Model - can provide a well-motivated scenario for successful baryogenesis if neutrinos…
Beyond the Standard Model Effective Field Theory: The Singlet Extended Standard Model
Shekhar Adhikari, Ian M. Lewis, Matthew Sullivan
One of the assumptions of simplified models is that there are a few new particles and interactions accessible at the LHC and all other new particles are heavy and decoupled. The ef…
Higgs Troika for Baryon Asymmetry
Hooman Davoudiasl, Ian M. Lewis, Matthew Sullivan
To explain the baryon asymmetry of the Universe, we extend the Standard Model (SM) with two additional Higgs doublets with small vacuum expectation values. The additional Higgs fie…
Searching for Dark Photons with Maverick Top Partners
Jeong Han Kim, Samuel D. Lane, Hye-Sung Lee +2
In this paper, we present a model in which an up-type vector-like quark (VLQ) is charged under a new gauge force which kinetically mixes with the SM hypercharge. The gauge…
Galactic Dark Matter Population as the Source of Neutrino Masses
Hooman Davoudiasl, Gopolang Mohlabeng, Matthew Sullivan
We propose that neutrino masses can be zero and may be generated by the local distribution of dark matter through a feeble long range scalar force. We discuss potential…
Enhanced di-Higgs Production in the Complex Higgs Singlet Model
S. Dawson, M. Sullivan
We consider the Standard Model extended by the addition of a complex scalar singlet, with no assumptions about additional symmetries of the potential. This model provides for reson…
Benchmarks for Double Higgs Production in the Singlet Extended Standard Model at the LHC
Ian M. Lewis, Matthew Sullivan
The simplest extension of the Standard Model is to add a gauge singlet scalar, : the singlet extended Standard Model. In the absence of a symmetry and if…
