膨胀子辅助的暗物质

Dilaton-assisted Dark Matter

Yang Bai, Marcela Carena, Joseph Lykken

摘要:

暗子可能是标准模型场和暗物质之间的主要信使。测量的暗物质遗迹丰度将暗物质质量和自旋与共形破缺标度联系起来。根据核子质量,预测了暗物质-核子自旋无关的截面。我们计算了LEP和Tevatron实验中的电子介子的电流约束,以及费米LAT可以观测到的暗物质湮灭到电子介子的γ射线信号。

英文摘要:

A dilaton could be the dominant messenger between Standard Model fields and dark matter. The measured dark matter relic abundance relates the dark matter mass and spin to the conformal breaking scale. The dark matter-nucleon spin-independent cross section is predicted in terms of the dilaton mass. We compute the current constraints on the dilaton from LEP and Tevatron experiments, and the gamma-ray signal from dark matter annihilation to dilatons that could be observed by Fermi-LAT.
