Celestial Sphere: holography, CFT and amplitudes  (rescheduled)


This workshop will explore and establish connections between flat space holography, conformal field theory and scattering amplitudes. Newly discovered structures relating these three areas have arisen in the context of the 'celestial sphere,' the space of generators for the null conformal boundary of an asymptotically flat space-time. It is hoped that by bringing together experts from these fields, the existence and properties of 'celestial' conformal field theories can be better understood, with a view to applying, testing and generalizing techniques from scattering amplitudes and conformal field theory.

Specific topics to be discussed include:

  • scattering amplitudes in the conformal primary basis
  • conformal soft theorems

  • celestial OPEs

  • conformal bootstrap, positivity and celestial amplitudes

  • asymptotic symmetries


  • Tim Adamo (Edinburgh)

  • Monica Pate (Harvard)

  • Joan Simon (Edinburgh)

  • Tomasz Taylor (Northeastern)

This workshop has been postponed and further information will be posted when a new date has been agreed.
