On preheating in higgs inflation
Web1 de fev. de 2024 · We study particle production at the preheating era in inflation models with nonminimal coupling ξφ{sup 2} R and quartic potential λφ{sup 4}/4 for several cases: real scalar inflaton, complex scalar inflaton and Abelian Higgs inflaton. We point out that the preheating proceeds much more violently than previously thought. WebSudhakantha Girmohanta, Seung J. Lee, Yuichiro Nakai, Motoo Suzuki.
