Theories with massive gravitons allow for distinct gravitational wave and photon speeds. Detecting a time of flight difference would confirm these theories of broken Lorentz symmetry.

Area of Science:

  • Theoretical Physics
  • Gravitational Wave Astronomy

Background:

  • Theories with extra spin-two fields coupled to gravity can exhibit a massive phase.
  • This phase implies broken Lorentz symmetry, affecting spacetime properties.

Purpose of the Study:

  • To explore the implications of massive gravitons on gravitational wave phenomenology.
  • To identify observable signatures that could validate these theoretical frameworks.

Main Methods:

  • Analysis of theoretical models incorporating massive gravitons.
  • Investigation of gravitational wave propagation and interactions with photons.

Main Results:

  • Two types of gravitons (massive and massless) propagate with different velocities.
  • Newtonian potentials may be modified but can be protected by scale symmetry.

Conclusions:

  • The distinct velocities of massive and massless gravitons offer a unique observational window.
  • A measurable time-of-flight difference between gravitational waves and photons would be a strong indicator for these theories.
