Nonstandard cosmologies from physics beyond the Standard model

TL;DR

This paper reviews nonstandard cosmological models arising from physics beyond the Standard Model, emphasizing their implications for cosmology and the importance of both direct and indirect searches for new physics.

Contribution

It provides a brief overview of nonstandard cosmological scenarios resulting from extensions of particle physics beyond the Standard Model.

Findings

Nonstandard cosmologies extend the standard $\Lambda$CDM model.

Particle physics beyond the Standard Model influences cosmological evolution.

Cosmological consequences of new physics are crucial for understanding the universe.

Abstract

The modern cosmology is based on inflationary models with baryosynthesis and dark matter/energy.It implies extension of particle symmetry beyond the Standard model. Studies of physical basis of the modern cosmology combine direct searches for new physics at accelerators with its indirect non-accelerator probes, in which cosmological consequences of particle models play important role. The cosmological consequences of particle models inevitably go beyond the 'standard' cosmological $\Lambda$CDM model and some possible feature of such 'nonstandard'cosmological scenarios is the subject of the present brief review.
