摘　　要：暗物质的理论研究和实验探测是天体粒子物理学中的重要课题,这种物质可能是最轻的超对称粒子构成,并以玻色球和泡的方式存在.在复标量场模型中构造了带U(1)荷的Q泡模型,通过引入两种跑动势的方法计算了Q泡暗物质的特征半径和能量稳定性质,结果得到了Q泡在s基态和p、d、f激发态的U(1)荷和能量,计算了不同能级的能量差,分析了能级的简并性质.这一研究的物理意义在于Q泡暗物质可以发射不同能量的粒子,并为暗物质的实验探测提供一定的理论预测.Theory research and experiment exploration of dark matter are an important topic of astroparticle physics, and this kind of matter may be made up of the lightest supersymmetry particle and exist in the form of Bose ball and bubble. In this paper, Q bubble model with U（ 1 ） charges is constructed in complex scalar field model, and the energy stability and characteristic radius of Q bubble are calculated by using two running potentials. Moreover, U（ 1 ） charges and energies for s ground state and p, d, f and excited states are calculated. At the same time, the energy differences of different energy levels are also computed. The degenerate property of energy levels is analyzed as well. The physical meaning of these researches show that Q-bubble dark matter can emission particles in different energy, and it will provide a theoretical prediction for experimental observation of dark matter.
