量子引力中的暗物质

Dark Matter in Quantum Gravity

Xavier Calmet, Boris Latosh

摘要:

我们表明,量子引力,无论它的紫外线完成可能是,可以解释暗物质。事实上,除了最近以引力波形式观测到的无质量引力场外,量子引力的谱还包含两个质量场,自旋分别为2和0。如果这些场是长寿命的,它们可以很容易地解释暗物质。在这种情况下,暗物质将非常轻,并且只与标准模型粒子引力耦合。

英文摘要:

We show that quantum gravity, whatever its ultra-violet completion might be, could account for dark matter. Indeed, besides the massless gravitational field recently observed in the form of gravitational waves, the spectrum of quantum gravity contains two massive fields respectively of spin 2 and spin 0. If these fields are long-lived, they could easily account for dark matter. In that case, dark matter would be very light and only gravitationally coupled to the standard model particles.
