额外维度中作为定域标量的暗物质

Dark matter as a localized scalar in the extra dimension

E. O. Iltan

摘要:

我们考虑一个标准模型单重态,它可接近一个额外的维度,它的零模是局部的高斯轮廓周围的一个点不同于原点。该零模标量是暗物质的一个可能候选者,其湮灭率对额外维的紧致化半径、局域化宽度和位置敏感。对于非共振湮灭的情况,我们利用基于当前遗迹密度的湮灭率,估计了在距离原点\sim 3 \times局域宽度处的暗物质标量位置。

英文摘要:

We consider a standard model singlet which is accessible to a single extra dimension and its zero mode is localized with Gaussian profile around a point different than the origin. This zero mode scalar is a possible candidate for the dark matter and its annihilation rate is sensitive to the compactification radius of the extra dimension, the localization width and the position. For the case of non resonant annihilation, we estimated the dark matter scalar location around a point, at a distance \sim 3 \times localization width from the origin, by using the annihilation rate which is based on the current relic density.
