Flat Holography and BMS Particles

Abstract: Despite recent progress, a complete formulation of a holographic correspondence for flat spacetimes remains elusive.

Any viable formulation should be based on a correspondence between bulk and boundary states built upon the equivalence of unitary irreducible representations (UIRs) of the asymptotic symmetry group of flat spacetimes, the BMS group.

After an extended review on flat space holography, I will present recent new results that provide explicit wavefunctions for the UIRs of the BMS group (the so-called BMS particles). I will outline prospects for defining an S-matrix for BMS states that is free from infrared divergences.
