论文摘要
预计我们宇宙中携带宇宙字符串的缩放网络的存在预计将连续创建宇宙学扩展过程中具有保守电流的环路。这些循环辐射重力波，并可能稳定为离心支持的构型。我们表明，这个过程产生了沃顿群岛的不可还原人群，到目前为止尚未考虑。特别是，即使在字符串形成时没有创建循环，我们也希望今天有大量存在。我们确定它们的宇宙学分布，并估算其今天的遗物丰度，这是弦乐张力和当前能量量表的函数。这使我们可以排除此参数空间的新域。同时，在字符串电流上的某些条件下，Vortons被证明可以为字符串张力的所有值提供可行的原始暗物质候选者。他们的质量，自旋和电荷频谱广泛，沃顿顿在暗物质搜索中会有异常的现象学。
The existence of a scaling network of current-carrying cosmic strings in our Universe is expected to continuously create loops endowed with a conserved current during the cosmological expansion. These loops radiate gravitational waves and may stabilise into centrifugally supported configurations. We show that this process generates an irreducible population of vortons which has not been considered so far. In particular, we expect vortons to be massively present today even if no loops are created at the time of string formation. We determine their cosmological distribution, and estimate their relic abundance today as a function of both the string tension and the current energy scale. This allows us to rule out new domains of this parameter space. At the same time, given some conditions on the string current, vortons are shown to provide a viable and original dark matter candidate, possibly for all values of the string tension. Their mass, spin and charge spectrum being broad, vortons would have an unusual phenomenology in dark matter searches.
