具有quintessence的Schwarzschild-anti de Sitter散射和吸收截面

Scattering and absorption sections of Schwarzschild-anti de Sitter with quintessence

Valeria Ramírez, L. A. López, Omar Pedraza, V. E. Ceron

摘要:

本文研究了被质点包围的Schwarzschild-anti de Sitter黑洞的散射截面和吸收截面。得到了宇宙学常数和归一化因子的临界值。我们描述了事件视界和被精华包围的黑洞的极值条件。计算了散射截面的经典和半经典截面.在程函极限下,用sinc近似研究了吸收截面。我们考虑在特殊情况下的精华状态参数$ω=-2/3$和$ω=-1/2$。

英文摘要:

In this paper, we study the scattering and absorption sections of the Schwarzschild--anti de Sitter black hole surrounded by quintessence. The critical values of the cosmological constant and the normalization factor are obtained. We describe the event horizons and the extremal condition of the black hole surrounded by quintessence. The effects of quintessence on the classical and semi--classical scattering cross--sections have been estimated. Also, the absorption section is studied with the sinc approximation in the eikonal limit. We consider the quintessence state parameter in the particular cases $ω=-2/3$ and $ω=-1/2$.
