Publisher: | Elsevier Ltd. | Source: | Demir, D.A. (2014). Effects of curvature-Higgs coupling on electroweak fine-tuning. Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 733, 237-240. doi:10.1016/j.physletb.2014.05.002 | Abstract: | It is shown that nonminimal coupling between the Standard Model (SM) Higgs field and spacetime curvature, present already at the renormalizable level, can be fine-tuned to stabilize the electroweak scale against power-law ultraviolet divergences. 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. | URI: | https://doi.org/10.1016/j.physletb.2014.05.002 http://hdl.handle.net/11147/5446 |
