GUP对弯曲DGP引力黑洞中大量矢量和标量粒子隧穿的影响

The Effect of GUP to Massive Vector and Scalar Particles Tunneling From a Warped DGP Gravity Black Hole

Ali Övgün, Kimet Jusufi

摘要:

本文讨论了在广义不确定原理(GUP)作用下,有质量的矢量和标量粒子的质量和角动量对Hawking温度的影响。特别地,我们在量子隧穿方法的框架下计算了扭曲DGP引力模型中黑洞的Hawking温度。我们使用修改后的Proca和Klein-Gordon方程先前确定的GUP拉格朗日在一个扭曲的Dvali-Gabadadze-Porrati(DGP)度规的时空背景下,与Hamilton-Jacobi(HJ)和半经典(WKB)近似方法的帮助下。我们发现,作为扭曲DGP黑洞解的一个特例,Schwarzschild-de Sitter(SdS)黑洞的Hawking温度是可以确定的.此外,霍金温度受矢量和标量粒子的质量和角动量的影响,并取决于黑洞发射的是哪种类型的粒子。我们的结论是霍金谱的非热性质导致普朗克尺度的非热关联,揭示了黑洞蒸发中的信息悖论。

英文摘要:

This paper discusses the effects of the mass and the angular momentum of massive vector and scalar particles on the Hawking temperature manifested under the effects of the generalized uncertainty principle (GUP). In particular, we calculate the Hawking temperature of a black hole in a warped DGP gravity model in the framework of the quantum tunneling method. We use the modified Proca and Klein-Gordon equations previously determined from the GUP Lagrangian in the spacetime background of a warped Dvali-Gabadadze-Porrati (DGP) metric, with the help of Hamilton-Jacobi (HJ) and semiclassical (WKB) approximation methods. We find that as a special case of a warped DGP black hole solution, the Hawking temperature of a Schwarzschild-de Sitter (SdS) black hole can be determined. Furthermore, the Hawking temperature is influenced by the mass and the angular momentum of vector and scalar particles and depends on which of those types of particles is being emitted by the black hole. We conclude that the nonthermal nature of the Hawking spectrum leads to Planck-scale nonthermal correlations, shedding light on the information paradox in black hole evaporation.
