SIMIS+Shanghaitech Joint Seminar on Theoretical Physics: SL(2,C)\times D symmetry and conformal primary basis for massless fields

Speaker: Hongbao Zhang (Beijing Normal University)

Abstract: In this talk, I will show you the solutions to equations of motion for massless fields with arbitrary helicity in 4D Minkowski spacetime fall into the representation dictated by SL(2,C)\times D symmetry, where the dilatation D is understood as an emergent symmetry for massless fields. Then I will present the corresponding explicit solutions, where some of them appear missing in the literature and their implications are speculated.
