Higher Spin Gravity online-club : Dmitry Ponomarev

Le prochain séminaire de la série Higher Spin Gravity online-club, co-organisée par l’UMONS et l’Université de Tours, sera donné par Dmitry Ponomarev (ITMP Moscow).

Invariant traces of the flat space chiral higher-spin algebra as scattering amplitudes

We sum up two- and three-point amplitudes in the chiral higher-spin theory over helicities and find that these quite manifestly have the form of invariant traces of the flat space chiral higher-spin algebra. We consider invariant traces of products of higher numbers of on-shell higher-spin fields and interpret these as higher-point scattering amplitudes. This construction closely mimics its anti-de Sitter space counterpart, which was considered some time ago and was confirmed holographically.
