ABSTRACT

Research in astrophysics and cosmology is rapidly expanding nowadays as a precision science and became deeply interconnected with particle physics. In particular, we know that the major part of matter in the Universe consists of Dark Matter, which is the substance of unknown nature signaling a new physics. At present, scientists consider several different models and possible candidates for the role of Dark Matter, attempts are made to find them in direct and indirect experiments. For example, the Dark Matter could be composed of new weak-interacting massive particles – WIMPs, which are predicted by different supersymmetric extensions of the Standard Model. However, at present, such models are strongly restricted by the experiments on the Large Hadron Collider, which have not discovered any new particles beyond the Standard Model yet. Axion or similar light scalar particle represent another class of possible Dark Matter candidates, which, as a primary motivation, provide natural dynamical solution for the strong CP problem. In another promising class of models the Dark Matter consists of Q-balls. The present project is devoted to the study of axion Dark Matter models and theories with Q-balls, both are related by the existence of specific non-linear field configurations which may help to discover this form of matter. In contrast to a supersymmetric scenario, these classes of models are much less studied. Axion models predict very high density of particles in the Galaxy halo. As a consequence, such Dark Matter can form the Bose-Einstein condensate, in cosmological context this condensate represents a gravitationally bound ensemble of axions – the Bose stars. At present, there is no any exact quantitative answer to the question whether the axion-like Dark Matter had time to condense, and if the answer is positive, what is mass fraction of Bose stars in the total matter balance, despite this question is very important in choosing the strategy of experimental search for this form of Dark Matter. This situation is related to the absence of a strict quantitative description of the process of Bose-Einstein condensate formation in the cosmological context, as well as to the lack of understanding of the general properties of coherent field configurations in the form of non-topological solitons like Bose stars. Our group is planning to make a considerable contribution to the theory of non-topological solitons, such as Bose stars and Q-balls, as well as to study possible strategy of their search in astrophysical and cosmological observations in the framework of models where such objects can play a role of the Dark Matter in our Universe. In order to achieve this, we are planning the following. First, we plan to examine the properties of these objects, such as existence of upper bounds on their charge and energy, study the question of stability, which are important for their description in the cosmological context. Second, we plan to examine different regimes and stages of their evolution, starting from the epoch of their formation in the early Universe and ending at the present time. And third, we plan to obtain quantitative estimates for those known effects which are discussed in the literature only qualitatively so far, as well as to consider some less examined processes, which can affect the results of the experimental search for Bose stars and Q-balls.
