abstract

Spacetime nonmetricity can be studied experimentally through its couplings to fermions and photons. We use recent high-precision searches for Lorentz violation to deduce first constraints involving the 40 independent nonmetricity components down to levels of order $10^{-43}$ GeV.

Discussion (0). Continue with ORCID to comment.

  1. Signals of nonrenormalizable Lorentz and CPT violation at the LHC

    hep-ph 2024-12 conditional novelty 6.0 of 10

    New LHC-derived bounds and projected sensitivities are obtained for dimension-five Lorentz- and CPT-violating quark operators through Z-boson exchange in Drell-Yan production.

  2. Equivalence Principle violation in metric-affine gravity and finite-temperature effects

    gr-qc 2026-06 unverdicted novelty 4.0 of 10

    Metric-affine gravity formulates equivalence principle violations via non-metricity that parallel finite-temperature mass-ratio shifts, and a generalized Fermi-Walker derivative shows no orthonormal tetrad propagates ...
