I will discuss a simple extension of the SM with just an additional scalar singlet coupling to the Higgs. My main focus will be the possible probes of electroweak baryogenesis in this model including collider searches gravitational wave detection and direct dark matter detection experiments. I will show there are regions in the parameter space where observation of gravitational waves is the most p

Among various scenarios of baryon asymmetry of the Universe, electroweak baryogenesis is directly connected with physics of the Higgs sector. We discuss spectra of gravitational waves which are originated by the strongly first order phase transition at the electroweak symmetry breaking, which is required for a successful scenario of electroweak baryogenesis. In the Z_3 symmetric singlet scalar mod

I will present the Idea of an inflaton without direct couplings to any additional fields. I will show a possible mechanisms of reheating via gravity together with implications of such an approach to inflation on predictions of inflation, dark energy, dark matter, thermal history of the Universe, electro-weak phase transition and especially gravitational waves production.

The study of the renormalization group improved effective potential of the Standard Model has revealed existence of a local maximum at field strengths of the order of 10^10 GeV. If the Standard Model is valid for very high energy scales, then the possibility of the production of cosmological domain walls in the early Universe occurs.
We investigated dynamics of networks of domain walls using l

In theories with spontaneous symmetry breaking it is possible to calculate the critical temperature of the phase transition between the symmetric and broken phases of the theory. In the Standard Model and its extensions, the temperature of the electroweak phase transition is interesting for a number of physical questions – for example when considering the observed matter/antimatter asymmetry, or

With increasing accuracy of CMB data, a thorough, quantitative understanding of the post-inflationary reheating era becomes more and more important for constraining different models of inflation. In particular, a precise computation of the non-homogeneous field evolution during preheating is desirable.In this talk I will present results of such computation for alpha-attractors models of inflation.

We find exact solutions to the wave equation of scalar field in the background of five-dimensional Einstein-Maxwell theory with cosmological constant where the scalar field couples to the electromagnetic field as well as to the cosmological term with two different coupling constants. We find that the five-dimensional spacetime is non-stationary and is a conformally regular spacetime, everywhere.
