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. |
