Massive gravitational waves from the Cosmic Defect theory

  title={Massive gravitational waves from the Cosmic Defect theory},
  author={Ninfa Radicella and Angelo Tartaglia},
The Cosmic Defect theory (CD), which is presented elsewhere in this conference, introduces in the standard Einstein‐Hilbert Lagrangian an elastic term accounting for the strain of space‐time viewed as a four‐dimensional physical continuum. In this framework the Ricci scalar acts as the kinetical term of the strain field whose potential is represented by the additional terms. Here we are presenting the linearised version of the theory in order to analyze its implications in the weak field limit… CONTINUE READING
