Non-Abelian R-symmetries in supersymmetry
James Brister, Longjie Ran, Zheng Sun
We investigate non-Abelian R-symmetries in supersymmetric theory, where fields may transform under the R-symmetry in representations with dimension higher than one.…
A brute-force search for R-symmetric Wess-Zumino models
James Brister, Shihao Kou, Zhengyi Li +2
This work makes an exhaustive search for generic renormalizable R-symmetric Wess-Zumino models with up to 5 chiral fields, and checks the consistency of their vacuum solutions with…
Novel counterexample to the Nelson-Seiberg theorem
James Brister, Zheng Sun
We present a new type of counterexample to the Nelson-Seiberg theorem. It is a generic R-symmetric Wess-Zumino model with nine chiral superfields, including one field of R-charge 2…
A formal notion of genericity and term-by-term vanishing superpotentials at supersymmetric vacua from R-symmetric Wess-Zumino models
James Brister, Zheng Sun, Greg Yang
It is known in previous literature that if a Wess-Zumino model with an R-symmetry gives a supersymmetric vacuum, the superpotential vanishes at the vacuum. In this work, we establi…
Perturbative calculation of field space entanglement entropy
James Brister
We present a general method for the perturbative calculation of the entanglement entropy between two interacting quantum fields. Previous attempts at calculating this quantity pert…
Effective matter dispersion relation in quantum covariant Horava-Lifshitz gravity
Jean Alexandre, James Brister
We study how quantum fluctuations of the metric in covariant Horava-Lifshitz gravity influence the propagation of classical fields (complex scalar and photon). The effective Lorent…
Fermion effective dispersion relation for z=2 Lifshitz QED
Jean Alexandre, James Brister
We study consequences of Lorentz symmetry violation in a z=2 Lifshitz extension of QED in 3+1 dimensions, and we discuss non-trivial effects of quantization. Because of the specifi…
