Seminar
Flat Space Scattering Amplitudes in Conformal Basis
Mr Ho Tat Lam
Princeton University

IAS4042, 4/F, Lo Ka Chung Building, Lee Shau Kee Campus, HKUST
In this talk, the speaker will present
the Lorentz transformations of flat spacetime act as conformal transformations on the celestial sphere. This makes it possible to construct conformal correlators from flat space amplitudes.
He will first review the recent progress on this construction through conformal primary wave functions
and discuss the implication of unitary and crossing symmetry. Lastly,
he will comment on its connection to AdS/CFT (anti-de Sitter/conformal field theory) and flat space holography.
The seminar is free and open to the public. No registration is required. Seating is on a first come, first served basis.
