论文摘要
如果载体玻色子通过非平凡的动力学功能偶联，则在通货膨胀期间可以形成空间均匀的载体冷凝物。这种巨大的载体玻色子的相干振荡是暗物质的候选者。在本文中，我们考虑了载体玻色子能量密度在通货膨胀期间增加并表明曲率/等离子扰动对这种情况的严格约束。
A spatially uniform vector condensate can be formed during inflation if the vector boson is coupled to the inflaton through nontrivial kinetic function. The coherent oscillation of such a massive vector boson is a dark matter candidate. In this paper we consider the case where the vector boson energy density increases during inflation and show that the curvature/isocurvature perturbation gives stringent constraint on this scenario.
