Description
To compute observables in the pure spinor description of 11D supergravity we need vertex operators, a good handle on the pure spinor measure, and a prescription for constructing invariants in pure spinor superspace. In this talk I will describe recent work [2305.19898 ] on the construction of superfields and vertex operators. This entails obtaining recursion relations for the superfields by appropriately gauge fixing the linearized superspace equations of motion. At the end of the talk I will also discuss upcoming work on the pure spinor measure.
