Measuring the tth coupling from SSDL+2b measurements
David Curtin, Jamison Galloway, Jay G. Wacker
We evaluate the potential of a dedicated search for tth production in the SSDL+2b channel. Such a measurement provides direct access to the top Yukawa coupling, since the sensitivi…
Models of Goldstone Gauginos
Daniele S. M. Alves, Jamison Galloway, Matthew McCullough +1
Models with Dirac gauginos provide appealing scenarios for physics beyond the standard model. They have smaller radiative corrections to the Higgs mass, a suppression of certain SU…
Signatures of Extra Dimensions from Upsilon Decays with a Light Gaugephobic Higgs Boson
Jamison Galloway, Bob McElrath, John McRaven
We explore non-standard Higgs phenomenology in the Gaugephobic Higgs model in which the Higgs can be lighter than the usually quoted current experimental bound. The Higgs propagate…
New Prospects for Higgs Compositeness in h -> Z gamma
Aleksandr Azatov, Roberto Contino, Andrea Di Iura +1
We discuss novel effects in the phenomenology of a light Higgs boson within the context of composite models. We show that large modifications may arise in the decay of a composite…
Superconformal Technicolor
Aleksandr Azatov, Jamison Galloway, Markus A. Luty
In supersymmetric theories with a strong conformal sector, soft supersymmetry breaking at the TeV scale naturally gives rise to confinement and chiral symmetry breaking at the same…
Minimal Conformal Technicolor and Precision Electroweak Tests
Jared A. Evans, Jamison Galloway, Markus A. Luty +1
We study the minimal model of conformal technicolor, an SU(2) gauge theory near a strongly coupled conformal fixed point, with conformal symmetry softly broken by technifermion mas…
Model-Independent Bounds on a Light Higgs
Aleksandr Azatov, Roberto Contino, Jamison Galloway
We present up-to-date constraints on a generic Higgs parameter space. An accurate assessment of these exclusions must take into account statistical, and potentially signal, fluctua…
Flavor in Minimal Conformal Technicolor
Jared A. Evans, Jamison Galloway, Markus A. Luty +1
We construct a complete, realistic, and natural UV completion of minimal conformal technicolor that explains the origin of quark and lepton masses and mixing angles. As in "bosonic…
Phenomenology of Induced Electroweak Symmetry Breaking
Spencer Chang, Jamison Galloway, Markus Luty +2
We study the phenomenology of models of electroweak symmetry breaking where the Higgs potential is dominated by a positive quadratic term destabilized by a tadpole arising from the…
Induced Electroweak Symmetry Breaking and Supersymmetric Naturalness
Jamison Galloway, Markus A. Luty, Yuhsin Tsai +1
In this paper we study a new class of supersymmetric models that can explain a 125 GeV Higgs without fine-tuning. These models contain additional `auxiliary Higgs' fields with larg…
A UV complete partially composite-pNGB Higgs
Jamison Galloway, Alexander L. Kagan, Adam Martin
We explore an electroweak symmetry breaking (EWSB) scenario based on the mixture of a fundamental Higgs doublet and an SU(4)/Sp(4) composite pseudo-Nambu-Goldstone doublet -- a par…
Searching for Signs of the Second Higgs Doublet
Nathaniel Craig, Jamison Galloway, Scott Thomas
The search for evidence of extended electroweak symmetry breaking has entered a new phase with the discovery of a Standard Model (SM)-like Higgs at the LHC. The measurement of Higg…
On the 750 GeV di-photon excess
Wolfgang Altmannshofer, Jamison Galloway, Stefania Gori +3
We explore several perturbative scenarios in which the di-photon excess at 750 GeV can potentially be explained: a scalar singlet, a two Higgs doublet model (2HDM), a 2HDM with an…
Anomalies, Unparticles, and Seiberg Duality
Jamison Galloway, John McRaven, John Terning
We calculate triangle anomalies for fermions with non-canonical scaling dimensions. The most well known example of such fermions (aka unfermions) occurs in Seiberg duality where th…
Superconformal Technicolor: Models and Phenomenology
Aleksandr Azatov, Jamison Galloway, Markus A. Luty
In supersymmetric theories with a strong conformal sector, soft supersymmetry breaking naturally gives rise to confinement and chiral symmetry breaking in the strong sector at the…
Early Higgs Hints for Non-Minimal Supersymmetry
Aleksandr Azatov, Spencer Chang, Nathaniel Craig +1
We discuss the role that Higgs coupling measurements can play in differentiating supersymmetric extensions of the Standard Model. Fitting current LHC data to the Higgs couplings, w…
Determining Higgs couplings with a model-independent analysis of h ->gamma gamma
Aleksandr Azatov, Roberto Contino, Daniele Del Re +3
Discovering a Higgs boson at the LHC will address a major outstanding issue in particle physics but will also raise many new questions. A concerted effort to determine the coupling…
Light Custodians and Higgs Physics in Composite Models
Aleksandr Azatov, Jamison Galloway
Composite Higgs models involving partial compositeness of Standard Model fermions typically require the introduction of fermionic partners which are relatively light in realistic s…
Gaugephobic Higgs Signals at the LHC
Jamison Galloway, Bob McElrath, John McRaven +1
The Gaugephobic Higgs model provides an interpolation between three different models of electroweak symmetry breaking: Higgsless models, Randall-Sundrum models, and the Standard Mo…
Contextualizing the Higgs at the LHC
Aleksandr Azatov, Roberto Contino, Jamison Galloway
Recent excesses across different search modes of the collaborations at the LHC seem to indicate the presence of a Higgs-like scalar particle at 125 GeV. Using the current data sets…
Goldstone Gauginos
Daniele S. M. Alves, Jamison Galloway, Matthew McCullough +1
Models of supersymmetry with Dirac gauginos provide an attractive scenario for physics beyond the standard model. The "supersoft" radiative corrections and suppressed SUSY producti…
Electroweak Symmetry Breaking and the Higgs Boson: Confronting Theories at Colliders
Aleksandr Azatov, Jamison Galloway
In this review, we discuss methods of parsing direct and indirect information from collider experiments regarding the Higgs boson and describe simple ways in which experimental lik…
Comments on "Gauge Fields and Unparticles"
Jamison Galloway, Damien Martin, David Stancato
The derivation of Feynman rules for unparticles carrying standard model quantum numbers is discussed. In particular, this note demonstrates that an application of Mandelstam's appr…
Running Electroweak Couplings as a Probe of New Physics
Daniele S. M. Alves, Jamison Galloway, Joshua T. Ruderman +1
The energy dependence of the electroweak gauge couplings has not been measured above the weak scale. We propose that percent-level measurements of the energy dependence of $α_{1,2…
