论文摘要
一个由纯非亚伯仪表理论组成的新的黑暗部门与SM颗粒没有可重新分布的相互作用，因此可以实现引力暗物质（DM）。量规交互限于$λ_ {\ rm dm} $，以典型的寿命$τ\ sim m _ {\ rm pl}^4/λ^5 _ {\ rm dm} $提供界限状态，如果$λ_ {\ rm dm dm dm dm dm iS te。此外，群体理论性质的意外对称性产生特殊的重力稳定结合状态。在有通用Planck抑制的运算符的情况下，这些状态已长期存在：su $（n）$仪表理论包含$τ\ sim m _ {\ rm pl}^8/λ^9 _ {\ rm dm dm dm} $;甚至更长的寿命$τ=（m _ {\ rm pl}/λ_ {\ rm dm}）^{2n-4}/λ_{\ rm dm} $来自so $（n）$ n \ ge 8 $，并且可能来自$ n \ ge 8 $，并且可能来自$ n \ ge 8 $，并且可能来自$ f_4 $ f_4 $或$ e__ $或$ e__ $ e__8 $。我们计算了由重力冻结和通货膨胀波动产生的遗物丰度，发现它们可以作为$λ_{\ rm dm} \ gtrsim 10^{10} $ gev的可行DM候选者。
A new dark sector consisting of a pure non-abelian gauge theory has no renormalizable interaction with SM particles, and can thereby realise gravitational Dark Matter (DM). Gauge interactions confine at a scale $Λ_{\rm DM}$ giving bound states with typical lifetimes $τ\sim M_{\rm Pl}^4/Λ^5_{\rm DM}$ that can be DM candidates if $Λ_{\rm DM} $ is below 100 TeV. Furthermore, accidental symmetries of group-theoretical nature produce special gravitationally stable bound states. In the presence of generic Planck-suppressed operators such states become long-lived: SU$(N)$ gauge theories contain bound states with $τ\sim M_{\rm Pl}^8/Λ^9_{\rm DM}$; even longer lifetimes $τ= (M_{\rm Pl}/Λ_{\rm DM})^{2N-4}/Λ_{\rm DM}$ arise from SO$(N)$ theories with $N \ge 8$, and possibly from $F_4$ or $E_8$. We compute their relic abundance generated by gravitational freeze-in and by inflationary fluctuations, finding that they can be viable DM candidates for $Λ_{\rm DM} \gtrsim 10^{10}$ GeV.
