An Operator Analysis of Radiative Muon Decay
Arvind Rajaraman, Chao-Hsiang Sheu
New physics beyond the Standard Model (SM) may induce new four-fermion interactions. We investigate the sensitivity of radiative muon decay, , to such four-f…
Revisiting fermion bound states in baby Skyrme background with Dzyaloshinskii Moriya interaction
Arvind Rajaraman, Chao-Hsiang Sheu, Alexander Stewart
In this paper, we investigate a fermion coupled to a Skyrme model in dimensions, where the Skyrmion is stabilized by the Dzyaloshinskii-Moriya and Skyrme interactions under a…
More on Classical Stability of Hopf-like Solitons of the Toroidal-Twisted type
Chao-Hsiang Sheu, Mikhail Shifman
The Faddeev-Hopf model [1] supporting Hopfions was shown to emerge in the low-energy limit of four-dimensional scalar quantum electrodynamics (QED) with two charged scalar fields […
Nonperturbative features in the Lie-algebraic Kähler sigma model with fermions
Chao-Hsiang Sheu
We investigate the trans-series structure of a quantum mechanical system originating from a Lie-algebraic Kähler sigma model with multiple right-handed chiral fermions, extending p…
Lie-algebraic Kähler sigma models with the U(1) isotropy
Chao-Hsiang Sheu, Mikhail Shifman
We discuss various questions which emerge in connection with the Lie-algebraic deformation of sigma model in two dimensions. First we supersymmetrize the original m…
Remarks on Baby Skyrmion Lie-Algebraic Generalization
Chao-Hsiang Sheu, Mikhail Shifman
We discuss generalized baby Skyrmions emerging in a (1+2)-dimensional model with a certain Lie-algebraic structure. The same result applies to the Polyakov-Belavin instantons i…
Consistency of SB in chiral Yang-Mills theory with adiabatic continuity
Chao-Hsiang Sheu, Mikhail Shifman
We study the pattern of chiral symmetry breaking (SB) in the model (with the chiral fermion sector containing , , and , see [1]) on $\mat…
Plasmons in semiconductor and topological insulator wires with large dielectric constant
Yi Huang, Chao-Hsiang Sheu, B. I. Shklovskii
The dispersion law of plasmons running along thin wires with radius is known to be practically linear. We show that in a wire with a dielectric constant much larger than th…
Treating Divergent Perturbation Theory: Lessons from Exactly Solvable 2D Models at Large
Daniel Schubring, Chao-Hsiang Sheu, Mikhail Shifman
We consider the operator product expansion (OPE) of correlation functions in the supersymmetric non-linear sigma model at sub-leading order in the large limit in order t…
Long Way to Ricci Flatness
Jin Chen, Chao-Hsiang Sheu, Mikhail Shifman +2
We study two-dimensional weighted supersymmetric models with the goal of exploring their infrared (IR) limit. are sim…
From Gauged Linear Sigma Models to Geometric Representation of in 2D
Chao-Hsiang Sheu, Mikhail Shifman
In this paper two issues are addressed. First, we discuss renormalization properties of a class of gauged linear sigma models (GLSM) which reduce to non…
