英文摘要	In this paper, the gravitational deflection of a relativistic massive neutral particle in the Schwarzschild-de Sitter spacetime is studied via the Rindler-Ishak method in the weak-field limit. When the initial velocity v0 of the particle tends to the speed of light, the result is consistent with that obtained in the previous work for the light-bending case. Our result is reduced to the Schwarzschild deflection angle of massive particles up to the second order, if the contributions from the cosmological constant Lambda are dropped. The observable correctional effects due to the deviation of v0 from light speed on the Lambda -induced contributions to the deflection angle of light are also analyzed.
