We study the bending of light in the space-time of black holes in the four-dimensional Einstein-Gauss-Bonnet theory of gravity, recently proposed by Glavan and Lin in Phys. Rev. Lett., 124 (2020) 081301. Using the Rindler-Ishak method, the effect of Gauss-Bonnet coupling on the bending angle is studied. We show that a positive Gauss-Bonnet coupling gives a negative contribution to the Schwarzschild-de Sitter deflection angle, as one would expect.

Rindler-Ishak 方法在新型 4D Gauss-Bonnet-de Sitter 黑洞中弯曲光

我们在四维爱因斯坦-高斯-博内引力理论中研究了黑洞时空中的光弯曲，该理论最近由 Glavan 和 Lin 在Phys. 牧师莱特。, 124 (2020) 081301. 使用 Rindler-Ishak 方法，研究了 Gauss-Bonnet 耦合对弯曲角度的影响。我们表明正 Gauss-Bonnet 耦合对 Schwarzschild-de Sitter 偏转角有负面影响，正如人们所期望的那样。
