abstract

Certain momentum-dependent terms in the fermion sector of the Lorentz-violating Standard Model Extension (SME) yield solvable classical lagrangians of a type not mentioned in the literature. These cases yield new relatively simple examples of Finsler and pseudo-Finsler structures. One of the cases involves antisymmetric $d$-type terms and yields a new example of a relatively simple covariant lagrangian.

  1. New constraints on modified gravity with dimension-six operators from gravitational waves

    gr-qc 2026-08 conditional novelty 5.0 of 10

    A dimension-six Lorentz-violating gravity operator is linearized to obtain gravitational-wave dispersion relations, and time-of-flight data from GW170817 and GW150914 bound the coefficients to 10^-5 to 10^-4 m^2 (nonb...
