The nonminimal coupling acts as an extrinsic stabilizer with no effect on the loop structure of the SM, if gravity is classical. This novel fine-tuning scheme, which could also be interpreted within Sakharov's induced gravity approach, works neatly in extensions of the SM involving additional Higgs fields or singlet scalars.eninfo:eu-repo/semantics/openAccessElectroweak theoryHiggs fieldStandard modelFine-tuning schemeArticle2-s2.0-8489997968410.1016/j.physletb.2014.05.002
