Abstract
An experimental detection of graviton is extremely hard problem, however, there are different ways to evaluate a graviton mass if it is non-vanishing. Theories of massive gravity or theories with non-vanishing graviton mass initially have a number of pathologies such as discontinuities, ghosts etc. In last years theorists found ways to overcome weaknesses of such theories meanwhile observational features are also discussed. In the first publication reporting about the discovery of gravitational waves from the binary black hole system the LIGO-Virgo collaboration obtained the graviton mass constraint around [Formula: see text] eV (later the estimate was improved with new data). A comparable and consistent graviton mass constraint around [Formula: see text] eV has been obtained from analysis of the bright star S2 trajectory near the Galactic Center.
Highlights
In the first publication reporting about the discovery of gravitational waves from the binary black hole system the LIGO-Virgo collaboration obtained the graviton mass constraint around 1.2 × 10−22 eV
A few years ago Freeman Dyson discussed an opportunity to detect graviton and he concluded that at the moment an experimental detection of graviton is an extremely hard problem,[1] if a graviton has a mass as it is done in the framework of theories of massive gravity, there are different ways to constrain its mass
Pauli in 1939.2 In seventies a discontinuity of such approach for mg → 0 has been found.[3,4,5]. As it was the so-called screening could resolve the issue[6] and the approach is very close to GR within natural assumptions. Another pathology had been described[9, 10] where the authors found a presence of ghosts and inconsistencies in gravity theories with a finite range, such phenomena are usually called as Boulware – Deser ghosts
