Scalar Boson Stars: (Thermo)Dynamics and Gravitational Equilibria : Abstract / G.A.Kozlov // Физика элементарных частиц и атомного ядра. – 2025. – Т. 56, № 1. – C. 87. – URL: http://www1.jinr.ru/Pepan/v-56-1/04_Kozlov_ann.pdf. – We analyse the (thermo)dynamics of the scalar degrees of freedom in the scalar boson stars through the dark matter density under extreme conditions. The boson stars (BS) are studied in terms of a dark scalar sector in such a way that this sector is coupled to the Standard Model Higgs boson doublet plus gravity. The stability of the BS is investigated at the level of the interaction between the scalars with the scale invariance breaking triggered by the electroweak symmetry breaking plus gravity. Analytic methods have been applied to an effective version of the theory, the scalar “tower” approximation, which should preserve an exact scale invariance. The production of the scalar dark matter and its decay have been discussed.
