Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 740, 46-50. doi:10.1016/j.physletb.2014.11.038 | Abstract: | Here we show that, a hidden vector field whose gauge invariance is ensured by a Stueckelberg scalar and whose mass is spontaneously generated by the Standard Model Higgs field contributes to quadratic divergences in the Higgs boson mass squared, and even leads to its cancellation at one-loop when Higgs coupling to gauge field is fine-tuned. In contrast to mechanisms based on hidden scalars where a complete cancellation cannot be achieved, stabilization here is complete in that the hidden vector and the accompanying Stueckelberg scalar are both free from quadratic divergences at one-loop. This stability, deriving from hidden exact gauge invariance, can have important implications for modeling dark phenomena like dark matter, dark energy, dark photon and neutrino masses. The hidden fields can be produced at the LHC. | URI: | https://doi.org/10.1016/j.physletb.2014.11.038 http://hdl.handle.net/11147/5965 |
