Spin 1/2 bosons etc. in a theory with Lorentz violation

TL;DR

This paper demonstrates that a Lorentz-violating theory with unconventional supersymmetry predicts standard low-energy physics but introduces novel high-energy extensions, including bosons with spin 1/2, which are experimentally testable.

Contribution

It shows that a specific Lorentz-violating action leads to standard physics at low energy and novel predictions like spin 1/2 bosons at high energy.

Findings

Standard physics recovered at low energy

Testable high-energy extensions predicted

Bosons with spin 1/2 implied by Lorentz violation

Abstract

An action with unconventional supersymmetry was introduced in an earlier paper. Here it is shown that this action leads to standard physics for fermions and gauge bosons at low energy, but to testable extensions of standard physics for fermions at high energy and for fundamental bosons which have not yet been observed. For example, the Lorentz-violating equation of motion for these bosons implies that they have spin 1/2.
