Lorentz Invariance and Dark Matter

Tuesday December 1, 2020
2:00 pm


 Presenter:  Kevin Cahill, UNM
 Series:  Nuclear, Particle, Astroparticle and Cosmology (NUPAC) Seminars
 Abstract:  General relativity with fermions
has two independent symmetries:
general coordinate invariance and
internal local Lorentz invariance.

Internal local Lorentz invariance
may be implemented by bosons
that gauge the Lorentz group
and that have their own action.

These Lorentz bosons would couple to fermions
and generate a Yukawa potential
that violates the weak equivalence principle
and the inverse-square law.

Experiments looking for
such potentials imply that
Lorentz bosons, if they exist,
are nearly stable and
contribute to dark matter.
