粒子加速器中的半经典几何
Semiclassical geons at particle accelerators
摘要：
我们指出，在某些四维扩展的广义相对论内构造的Palatini形式主义稳定的自引力物体的离散的质量和电荷谱可能存在。在电磁场中引入非线性可以有效地将它们的质谱降低许多数量级。因此，这些物体可能在当前粒子加速器的范围内（或附近）。我们提供了一个完全可解的模型来支持这个想法。
英文摘要：
We point out that in certain four-dimensional extensions of general relativity constructed within the Palatini formalism stable self-gravitating objects with a discrete mass and charge spectrum may exist. The incorporation of nonlinearities in the electromagnetic field may effectively reduce their mass spectrum by many orders of magnitude. As a consequence, these objects could be within (or near) the reach of current particle accelerators. We provide an exactly solvable model to support this idea.
