Unitary gauge considered harmful
Tommy Anderberg
TL;DR
This paper critically examines the Higgs mechanism, emphasizing the importance of gauge choices, especially the unitary gauge, and explores implications for cosmology such as dark energy and the CMB cold spot.
Contribution
It highlights the limitations of the unitary gauge in understanding gauge symmetry breaking and discusses its implications for cosmological phenomena.
Findings
Unitary gauge can obscure fundamental aspects of gauge symmetry breaking.
Understanding gauge symmetry breaking requires careful gauge choice considerations.
Implications for cosmology include insights into domains, dark energy, and the CMB cold spot.
Abstract
I informally review the Higgs mechanism, focusing on fundamental aspects which should be common knowledge but apparently are not, explain why your understanding of gauge symmetry breaking is a decreasing function of your reliance on the unitary gauge, and discuss some implications for cosmology (domains, dark energy, CMB cold spot).
