Light inflaton -- connscting inflation and low energy experiments — •Fedor Bezrukov — Max-Planck-Institut für Kernphysik, Heidelberg, Germany

We study the phenomenology of a minimal extension of the Standard Model, where the inflation is provided by an additional light scalar field. It turns out, that the requirements of successful inflation and reheating after inflation bound the mass of the inflaton to the region 270 MeV -- 1.8 GeV. This mass region allows for experimental search of the inflaton in laboratory experiments, with rare meson decay and dedicated beam-target experiments being the most promising ones.
