A Minimal b Ghost
Artikel i vetenskaplig tidskrift, 2023

The b ghost, or b operator, used for fixing Siegel gauge in the pure spinor superfield formalism, is a composite operator of negative ghost number, satisfying (Formula presented.), where q is the pure spinor differential (BRST operator). It is traditionally constructed using non-minimal variables. However, since all cohomology has minimal representatives, it seems likely that there should be versions of physically meaningful operators, also with negative ghost number, using only minimal variables. The purpose of this letter is to demonstrate that this statement holds by providing a concrete construction in (Formula presented.) super-Yang–Mills theory, and to argue that it is a general feature in the pure spinor superfield formalism.
