杂化弦论中小黑洞的对产生

Pair Production of small Black Holes in Heterotic String Theories

Massimo Bianchi, Luca Lopez

摘要:

我们研究了在环面上紧化的杂种优势串和FHSV模型中小BPS BH的配对产生。在回顾了微扰BPS谱中小BH的识别之后,我们计算了由无质量矢量玻色子或引力子引发的过程的树级振幅。然后,我们分析所产生的截面的能量和角分布。最后,我们简要地评论scenari与大额外的维度和推广我们的结果,非BPS,非极值和旋转BH的。

英文摘要:

We study pair production of small BPS BH's in heterotic strings compactified on tori and in the FHSV model. After recalling the identification of small BH's in the perturbative BPS spectrum, we compute the tree-level amplitudes for processes initiated by massless vector bosons or gravitons. We then analyze the resulting cross sections in terms of energy and angular distributions. Finally, we briefly comment on scenari with large extra dimensions and on generalizations of our results to non-BPS, non-extremal and rotating BH's.
