小黑洞组分与水平对称性

Small Black Hole Constituents and Horizontal Symmetry

Anna Ceresole, Sergio Ferrara, Alessio Marrani, Armen Yeranyan

摘要:

利用水平对称SL(2,R)的作用,我们将两中心极端黑洞电荷组态的分析和分类推广到“小”单中心组分的情况。后者被认为是减少独立的水平不变多项式的数量从四个到一个,这取决于支持两个中心的电荷轨道的秩。在E7型的U-对偶群中,考虑了四维时空中的可约和不可约对称超引力模型,因此包含了N = 2和N = 8的理论。

英文摘要:

By exploiting the role of the horizontal symmetry SL(2,R), we extend the analysis and classification of two-centered extremal black hole charge configurations to the case of "small" single-centered constituents. These latter are seen to decrease the number of independent horizontal-invariant polynomials from four to one, depending on the rank of the charge orbit supporting each of the two centers. Within U-duality groups of type E7, both reducible and irreducible symmetric supergravity models in four space-time dimensions are considered, thus encompassing N = 2 and N = 8 theories.
