论文摘要
在本文中，我们研究了由于非交通性黑洞而通过部分波方法带有全局单极的无质量标量波散射的过程。我们在低频极限下计算了差分散射和吸收的横截面。我们还通过空测量方法以高频极限计算了吸收和阴影半径。我们表明，非交通性会导致差异散射/吸收横截面和阴影半径的减少，而全局单极的存在具有增加此类数量的值的作用。在零质量参数的极限中，我们验证了差分散射，吸收和阴影射线方法的横截面，以与最小质量成比例的非零值。
In this paper, we investigate the process of massless scalar wave scattering due to a noncommutative black hole with a global monopole through the partial wave method. We computed the cross section of differential scattering and absorption at the low frequency limit. We also calculated, at the high frequency limit, the absorption and the shadow radius by the null geodesic method. We showed that noncommutativity causes a reduction in the differential scattering/absorption cross section and shadow radius, while the presence of the global monopole has the effect of increasing the value of such quantities. In the limit of the null mass parameter, we verify that the cross section of differential scattering, absorption and shadow ray approach to a non-zero value proportional to a minimum mass.
