Web6 de nov. de 2009 · In this paper we study various particle physics effects of a light, scalar dark energy field with chameleon-like couplings to matter. We show that a chameleon model with only matter couplings will induce a coupling to photons. In doing so, we derive the first microphysical realization of a chameleonic dark energy model coupled to the … WebHiggs eld in the early Universe by recognizing Higgs as chameleon coupled to in aton after we rst general-ize the chameleon coupling for arbitrary background in Sec. II. The idea …

WebThe existing constraints from particle colliders reveal a suspicious but nonlethal metastability for our current electroweak vacuum of Higgs potential in the standard model of particle physics, which is, however, disfavored in the early Universe if the inflationary Hubble scale is larger than the instability scale when Higgs quartic self-coupling runs into negative … Web4 de jun. de 2024 · Higgs chameleon Research Outcome - May 26, 2024 Renormalization Group Evolution from On-shell SMEFT Research Outcome - May 20, 2024 ... blog hack console
