Concerning Bjorken's Model of Spontaneous Breakdown of Lorentz Invariance
Raghunath Acharya
TL;DR
This paper reexamines Bjorken's model of spontaneous Lorentz invariance breaking, revealing it predicts both a scalar Nambu-Goldstone boson and a photon, with implications for fundamental symmetries.
Contribution
It demonstrates that Bjorken's model inherently includes a scalar Nambu-Goldstone boson alongside the photon, clarifying the model's particle spectrum.
Findings
Presence of zero mass scalar Nambu-Goldstone boson
Existence of zero mass photon
Implications for Lorentz symmetry breaking
Abstract
We revisit Bjorken's model of spontaneous breakdown of Lorentz invariance. We show that the model possesses zero mass, spin zero (scalar) Nambu-Goldstone boson, in addition to the zero mass, spin one (vector) photon.
