论文摘要
使用理想化的吸积盘模型，我们研究了重力理论对中微子对an灭nip灭niperon-positron对（$ν{\barν} \ to e^-e^+$）的影响，发生在旋转轴附近。对于积聚磁盘，我们考虑了温度$ t =常数$和$ t \ propto r^{ - 1} $的模型。在这两种情况下，我们都发现重力理论导致增强，相对于一般相对论，中微子对歼灭的能量沉积速率的速率高达一个数量级。
Using idealized models of the accretion disk, we investigate the effects induced by the modified theories of gravity on the annihilation of the neutrino pair annihilation into electron-positron pairs ($ν{\bar ν}\to e^-e^+$), occurring near the rotational axis. For the accretion disk, we have considered the models with temperature $T=constant$ and $T\propto r^{-1}$. In both cases, we find that the modified theories of gravity lead to an enhancement, up to more than one order of magnitude with respect to General Relativity, of the rate of the energy deposition rate of neutrino pair annihilation.
