Title	Matter-antimatter asymmetric production due to oscillating background field
Abstract	In this talk, we discuss the scenario in which the non-perturbative particle production and the generation of the matter-antimatter asymmetry simultaneously due to an oscillation background field. This type of scenario occurs if the theory has the oscillating background field coherently, as similar to an inflation field, and has CP-violating parameters. To demonstrate the possibility of our scenario, we consider the type-I seesaw model as an illuminating example and show the numerical analysis. In order to generate the required lepton number $\|n_L/s\| = 2.4 \times 10^{-10}$, we find that the scale of the Higgs oscillation is required to be higher than $10^{14}$ GeV.
