dc.description.abstract |
© 2020, Springer Science+Business Media, LLC, part of Springer Nature. Free oscillations of scalar fields with a Higgs potential are investigated in cosmological models based on scalar fields, both in the case of isolated classical and phantom fields and in the case of an asymmetric scalar doublet. On the basis of numerical modeling, we have found dependences of the period of free oscillations with zero effective energy on the parameters of the field model and have also constructed energy spectra of the zero oscillations. These spectra display a thermal character, which allows us to interpret them as mass spectra of scalar bosons. |
