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, $μ^{-} \to e^{-} ν ˉ_{e} ν_{μ} γ$ , 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 $2 + 1$ 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 […
