标题： Black Holes as Fundamental Strings: Comparing the Absorption of Scalars

摘要： 最近提出的霍洛维茨和波奇斯基的“对应原理”提供了一种具体的方法，用于将带电的NS-NS电荷的黑洞与其他物体联系起来，并正确匹配它们的熵。 我们通过检查近极端黑洞对中性、最小耦合标量的吸收率中的灰体因子，进一步测试了这一对应关系。 也许令人惊讶的是，结果通常与弱耦合弦的吸收不一致。 尽管这并不否定该对应关系，但它表明在黑洞参数空间的这一区域，该对应关系可能并不简单。 在过程中，我们讨论了黑洞吸收匹配计算中的一些普遍问题。 显示英文摘要

摘要： The recently proposed ``correspondence principle'' of Horowitz and Polchinski provides a concrete means to relate (among others) black holes with electric NS-NS charges to fundamental strings and correctly match their entropies. We test further this correspondence by examining the greybody factors in the absorption rates of neutral, minimally coupled scalars by a near extremal black hole. Perhaps surprisingly, the results disagree in general with the absorption by weakly coupled strings. Though this does not disprove the correspondence, it indicates that it might not be simple in this region of the black hole parameter space. Along the way, we discuss some generic problems of the matching calculation of the absorption by black holes.
