Theoretical Aspects of Massive Gravity

Hinterbichler, Kurt

Understand

Massive gravity has seen a resurgence of interest due to recent progress which has overcome its traditional problems, yielding an avenue for addressing important open questions such as the cosmological constant naturalness problem.

  • The possibility of a massive graviton has been studied on and off for the past 70 years.
  • During this time, curiosities such as the vDVZ discontinuity and the Boulware-Deser ghost were uncovered.
  • We re-derive these results in a pedagogical manner, and develop the St\"ukelberg formalism to discuss them from the modern effective field theory viewpoint.
