Cosmological Solutions in the Tensor-Multi-Scalar Theory of Gravity with the Higgs Potential

Abstract

© 2020, Pleiades Publishing, Ltd. Abstract: We consider a generalization of Higgs inflation, based on cosmology of general relativity (GR), to the case of a two-field model of the tensor-multiscalar theory of gravity (TMS TG). Cosmological solutions are found in the case where a scalar field with the Higgs potential, as a source of TMS TG is in the slow-rolling mode. Solutions with power and exponential-power-law evolution of the scale factor are obtained for various limiting forms of the Higgs potential.
