论文摘要
仿射重力是一种基于连接的重力公式，不涉及度量。在回顾了仿射重力的基本特性后，我们通过弯曲的时空中的连接来计算标量粒子的树级散射幅度。我们发现，虽然在古典上等同于一般相对论，但仿射重力与公制量子重力不同。
Affine gravity is a connection-based formulation of gravity that does not involve a metric. After a review of basic properties of affine gravity, we compute the tree-level scattering amplitude of scalar particles interacting gravitationally via the connection in a curved spacetime. We find that, while classically equivalent to general relativity, affine gravity differs from metric quantum gravity.
