Higher Spin Gravity Amplitudes From Zero-form Charges
Nicolò Colombo, Per Sundell
We examine zero-form charges in Vasiliev's four-dimensional bosonic higher spin gravities. These are classical observables given by integrals over noncommutative twistor space of a…

A minimal BV action for Vasiliev's four-dimensional higher spin gravity
Nicolas Boulanger, Nicolo Colombo, Per Sundell
The action principle for Vasiliev's four-dimensional higher-spin gravity proposed recently by two of the authors, is converted into a minimal BV master action using the AKSZ proced…

Twistor space observables and quasi-amplitudes in 4D higher spin gravity
Nicolo Colombo, Per Sundell
Vasiliev equations facilitate globally defined formulations of higher-spin gravity in various correspondence spaces associated with different phases of the theory. In the four-dime…
