论文摘要
最近提出了一种新的聚合物黑洞溶液。聚合物黑洞和Schwarzschild黑洞之间的差异是由量子参数$ a $捕获的。为了获得对参数$ a $的约束，我们考虑使用太阳系实验对$ a $施加的观察性约束，并计算光的偏转，shapiro Time延迟，透明节序，并获得与参数$ a $ a $相关的效果。此外，还进行了该循环量子重力黑洞的参数化后牛顿后方法。事实证明，$ a $的最紧密约束可以提高到$ 0 <a <a <4.0 \ times10^{ - 6} $。
A new polymer black hole solution in loop quantum gravity was proposed recently. The difference between the polymer black hole and Schwarzschild black hole is captured by a quantum parameter $A$. In order to get the constraints on parameter $A$, we consider the observational constraints imposed on $A$ by using the Solar System experiments and calculate the deflection of light, Shapiro time delay, perihelion precession and obtain the effects associated with parameter $A$. Moreover, the parameterized post-Newtonian approach of this loop quantum gravity black hole was also carried out. It turns out the tightest constraint on $A$ can be improved to $0<A<4.0\times10^{-6}$.
