摘要

我们考虑了基于标量-扭转引力的宇宙学模型，这意味着扭转与标量场之间存在非极小耦合，模型参数之间存在一定的关系。基于对宇宙学扰动参数值的观测约束，确定了耦合的类型。有人指出，根据所提出的方法建立的任何暴胀模型都可以通过观测限制加以验证。

Reconstruction of the Scalar-Torsion Gravity Version from the Frame of Exact Cosmological Solutions

We consider cosmological models based on the scalar-torsion gravity implying non-minimal coupling between torsion and the scalar field with certain relations between model’s parameters. Based on observational constraints on the values of the parameters of cosmological perturbations, the type of the coupling was determined. It was noted that any inflationary models constructed on the basis of the proposed approach can be verified by observational constraints.

期刊介绍： Physics of Atomic Nuclei is a journal that covers experimental and theoretical studies of nuclear physics: nuclear structure, spectra, and properties; radiation, fission, and nuclear reactions induced by photons, leptons, hadrons, and nuclei; fundamental interactions and symmetries; hadrons (with light, strange, charm, and bottom quarks); particle collisions at high and superhigh energies; gauge and unified quantum field theories, quark models, supersymmetry and supergravity, astrophysics and cosmology.
