SUMMARY:Theoretical Physics Colloquium: Julio Parra-Martinez – Tidal Love
  numbers and scattering amplitudes
DESCRIPTION:Tidal Love numbers and scattering amplitudes\n\nTidal Love numb
 ers quantify the deformability and dissipative properties of compact gravi
 tating objects. However\, even in classical GR\, they undergo renormalizat
 ion group running due to the nonlinearity of gravity. In this talk I will 
 explain some exact results about their running\, which can be extracted by
  matching calculations of scattering amplitudes in black hole perturbation
  theory and point-particle effective theories. Due to the universality of 
 EFT\, the results have applications to the physics of black holes\, neutro
 n stars\, and even binary systems. For the specific case of black holes\, 
 our matching calculation also provides the precise values of both static a
 nd dynamical Love numbers in various dimensions.
