The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The sensitivity of experiments with neutral mesons to possible indirect CPT violation is examined. It is shown that experiments conventionally regarded as equivalent can have CPT reaches differing by orders of magnitude within the framework of a minimal CPT- and Lorentz-violating extension of the standard model.

The report argues that a 75 ab^-1 e+e- flavour factory could probe new physics at 10-100 TeV and discriminate among models through correlated rare-decay and CP measurements.
Modern tests of Lorentz invariance
gr-qc 2005-02 accept novelty 2.0 of 10

No experiment has found Lorentz violation, and the combined terrestrial and astrophysical bounds are tight enough to exclude a generic Planck-scale origin for the effect at mass dimension six or below.

8 arXiv papers cite this in 13 sentences

Each citing sentence is taken from the citing paper's LaTeX source and typed by Pith's classifier. A label appears at probability 0.8 or more (0.95 for support), a contest at 0.7 or more; the quoted words are the citing authors'. How each label was checked · JSON

It depends on the four-velocity $β^μ=(γ,γβ⃗)$ of the neutral meson as [ref] [equation] thereby breaking Lorentz invariance.
