Abstract

We use a simplified formalism to recompute the single graviton loop contribution to the self-mass of a massless, conformally coupled scalar on de Sitter background which was originally made by Boran et al., [Phys. Rev. D 90, 124054 (2014); PRVDAQ1550-799810.1103/PhysRevD.90.12405496, 025001 (2017); PRVDAQ2470-001010.1103/PhysRevD.96.02500196, 105003 (2017)PRVDAQ2470-001010.1103/PhysRevD.96.105003]. Our result resolves the problem with the flat space correspondence limit that was pointed out by Fröb [Classical Quantum Gravity 35, 035005 (2018)CQGRDG0264-938110.1088/1361-6382/aa9ad1]. We discuss how this computation will be used in a long-term project to purge the linearized effective field equation of gauge dependence.
