摘要：

我们分析了暗物质候选者来自隐标量扇区的近似标度对称理论的可能性。这项研究包括暖暗物质方案和玻色-爱因斯坦凝聚，这可能导致标量玻色子星（BS）引起的直接检测通过观察的主要（直接）光子。本文考虑了标量粒子--声子在有限温度和有限化学势下的动力学系统。随着温度的升高，颗粒密度的波动急剧增大。当相变临近时，相对化学势的基态趋于一个临界值时，粒子密度的涨落出现非单调上升，并伴随着无穷多个粒子。我们的结果表明，在BS的相变可以通过共形异常直接诱导的初级光子产额的波动来确定。光子的涨落率在红外波段强烈增长，在相变时变得很大。

英文摘要：

We analyse the possibility that the dark matter candidate is from the approximate scale symmetry theory of the hidden scalar sector. The study includes the warm dark matter scenario and the Bose-Einstein condensation which may lead to the scalar boson stars (BS) giving rise to direct detection through the observation of the primary (direct) photons. The dynamical system of the scalar particles, the dilatons, at finite temperature and chemical potential is considered. The fluctuation of the particle density increases sharply within the increasing of the temperature. When the phase transition approaches, the fluctuation of the particle density has the non-monotonous rising when the ground state of the relative chemical potential tends to the critical value equal to one accompanying by the infinite number of particles. Our results suggest that the phase transition in the BS may be identified through the fluctuation in yield of primary photons induced directly by the conformal anomaly. The fluctuation rate of the photons grows up intensively in the infra-red to become very large at the phase transition.
