Higgs Mass from D-Terms: a Litmus Test
Clifford Cheung, Hannes L. Roberts
We explore supersymmetric theories in which the Higgs mass is boosted by the non-decoupling D-terms of an extended gauge symmetry, defined here to be a general linear comb…
Supersymmetry with Light Stops
Grant Larsen, Yasunori Nomura, Hannes L. L. Roberts
Recent LHC data, together with the electroweak naturalness argument, suggest that the top squarks may be significantly lighter than the other sfermions. We present supersymmetric m…
Dressed-quarks and the Roper resonance
Craig D. Roberts, Ian C. Cloet, Lei Chang +1
A Dyson-Schwinger equation calculation of the light hadron spectrum, which correlates the masses of meson and baryon ground- and excited-states within a single framework, produces…
The Cosmological Constant in the Quantum Multiverse
Grant Larsen, Yasunori Nomura, H. L. L. Roberts
Recently, a new framework for describing the multiverse has been proposed which is based on the principles of quantum mechanics. The framework allows for well-defined predictions,…
pi- and rho-mesons, and their diquark partners, from a contact interaction
H. L. L. Roberts, A. Bashir, L. X. Gutierrez-Guerrero +2
We present a unified Dyson-Schwinger equation treatment of static and electromagnetic properties of pseudoscalar and vector mesons, and scalar and axial-vector diquark correlations…
Nucleation of Spontaneous Vortices in Trapped Fermi Gases Undergoing a BCS-BEC Crossover
A. Glatz, H. L. L. Roberts, I. S. Aranson +1
We study the spontaneous formation of vortices during the superfluid condensation in a trapped fermionic gas subjected to a rapid thermal quench via evaporative cooling. Our work i…
T(r)opical Dyson-Schwinger Equations
L. Chang, I. C. Cloet, C. D. Roberts +1
We provide a glimpse of recent progress in hadron physics made using QCD's Dyson-Schwinger equations, reviewing: the notion of in-hadron condensates and a putative solution of a gr…
Masses of ground and excited-state hadrons
H. L. L. Roberts, L. Chang, I. C. Cloet +1
We present the first Dyson-Schwinger equation calculation of the light hadron spectrum that simultaneously correlates the masses of meson and baryon ground- and excited-states with…
Abelian anomaly and neutral pion production
H. L. L. Roberts, C. D. Roberts, A. Bashir +2
We show that in fully-self-consistent treatments of the pion; namely, its static properties and elastic and transition form factors, the asymptotic limit of the product Q^2 G_{γ* γ…
Impact of dynamical chiral symmetry breaking on meson structure and interactions
H. L. L. Roberts, L. Chang, C. D. Roberts
We provide a glimpse of recent progress in meson physics made via QCD's Dyson-Schwinger equations with: a perspective on confinement and dynamical chiral symmetry breaking (DCSB);…
Exposing the dressed quark's mass
H. L. L. Roberts, L. Chang, I. C. Cloet +1
This snapshot of recent progress in hadron physics made in connection with QCD's Dyson-Schwinger equations includes: a perspective on confinement and dynamical chiral symmetry brea…
