Deviations from relativity are tightly constrained by numerous experiments. A class of unmeasured and potentially large violations is presented that can be tested in the laboratory only via weak-gravity couplings. Specialized highly sensitive experiments could achieve measurements of the corresponding effects. A single constraint of 1x10;{-11} GeV is extracted on one combination of the 12 possible effects in ordinary matter. Estimates are provided for attainable sensitivities in existing and…

Lorentz violation, gravitomagnetism, and intrinsic spin
A largely unconstrained set of relativity-violating effects is studied via the gravitomagnetic effect on intrinsic spins. The results of existing comagnetometer experiments are used to place
CPT and Lorentz-invariance violation
The largest gap in our understanding of nature at the fundamental level is perhaps a unified description of gravity and quantum theory. Although there are currently a variety of theoretical

Abstract In the last decade, a variety of high-precision experiments have searched for miniscule violations of Lorentz symmetry. These searches are largely motivated by the possibility of uncovering
Breaking diffeomorphism invariance and tests for the emergence of gravity
If general relativity is an emergent phenomenon, there may be small violations of diffeomorphism invariance. We propose a phenomenology of perturbatively small violations of general relativity by the
Gravity effects on antimatter in the standard-model extension
The gravitational Standard-Model Extension (SME) is the general field-theory based framework for the analysis of CPT and Lorentz violation. In this work we summarize the implications of Lorentz and
Probing the small-scale structure of spacetime
Many theoretical attempts at understanding the Planck-scale structure of spacetime can accommodate minute departures from Lorentz and CPT invariance. At presently attainable energies, such effects
Gravity, CPT, and the standard-model extension
Exotic atoms provide unique opportunities to search for new physics. The search for CPT and Lorentz violation in the context of the general field-theory based framework of the gravitational
Antimatter-gravity couplings, and Lorentz symmetry
Implications of possible CPT and Lorentz violation for antimatter-gravity experiments as well as other antimatter tests are considered in the context of the general field-theory-based framework of
Testing velocity-dependent CPT -violating gravitational forces with radio pulsars
In the spirit of effective field theory, the Standard-Model Extension (SME) provides a comprehensive framework to systematically probe the possibility of Lorentz/CPT violation. In the pure gravity
Gravitational physics with antimatter
The production of low-energy antimatter provides unique opportunities to search for new physics in an unexplored regime. Testing gravitational interactions with antimatter is one such opportunity.

Signals for CPT and Lorentz violation in neutral-meson oscillations
Experimental signals for indirect CPT violation in the neutral-meson systems are studied in the context of a general CPT- and Lorentz-violating standard-model extension. In this explicit theory, some
Sensitivity of CPT Tests with Neutral Mesons
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
Global three-parameter model for neutrino oscillations using Lorentz violation
A model of neutrino oscillations is presented that has only three degrees of freedom and is consistent with existing data. The model is a subset of the renormalizable sector of the Standard-Model
$CPT$ violation and the standard model
Spontaneous CPT breaking arising in string theory has been suggested as a possible observable experimental signature in neutral-meson systems. We provide a theoretical framework for the treatment of
CPT, strings, and meson factories.
TLDR
It is shown that spontaneous breaking of [ital CPT] can arise at a level within reach of experiments at meson factories currently being built or designed, and the likely experimental string signatures are discussed.
Lorentz violation and short-baseline neutrino experiments
A general discussion is given of signals for broken Lorentz symmetry in short-baseline neutrino experiments. Among the effects that Lorentz violation can introduce are a dependence on energy

TLDR
An improved Galilean experiment involving simultaneous free fall in vacuum of concentric masses with different compositions, sensitive to composition-dependent interactions between the falling masses and the Earth for forces with ranges exceeding 10 km or so that are less accessible to torsion balance experiments.
Testing Lorentz invariance and CPT conservation with NuMI neutrinos in the MINOS near detector.
TLDR
No evidence for a sidereal signal in the data set was found, implying that there is no significant change in neutrino propagation that depends on the direction of the neutrinos beam in a sun-centered inertial frame.
Signals for Lorentz violation in electrodynamics
An investigation is performed of the Lorentz-violating electrodynamics extracted from the renormalizable sector of the general Lorentz- and CPT-violating standard-model extension. Among the
