H-FGK形式体系中N=2,d=5超引力黑洞和黑弦

Black holes and black strings of N=2, d=5 supergravity in the H-FGK formalism

Patrick Meessen, Tomas Ortín, Jan Perz, C. S. Shahbazi

摘要:

我们研究了N=2,d=5超引力耦合到矢量多重态的极值和非极值静态黑洞解的一般类和性质,并将其推广到静态黑弦.我们解释了如何确定黑洞和黑弦解的积分常数和物理参数。我们推导出一些与模型无关的语句,包括将非极值流方程转换为极值流方程的形式。我们应用我们的方法构造的例子解决方案(其中一个新的极值弦解的杂化弦论在K_3 \times S^1)。在我们已经明确计算的情况下,非极值解的内视界和外视界的面积的乘积与具有相同电荷的极值解的视界的与模无关的面积的平方一致。

英文摘要:

We study general classes and properties of extremal and non-extremal static black-hole solutions of N=2, d=5 supergravity coupled to vector multiplets using the recently proposed H-FGK formalism, which we also extend to static black strings. We explain how to determine the integration constants and physical parameters of the black-hole and black-string solutions. We derive some model-independent statements, including the transformation of non-extremal flow equations to the form of those for the extremal flow. We apply our methods to the construction of example solutions (among others a new extremal string solution of heterotic string theory on K_3 \times S^1). In the cases where we have calculated it explicitly, the product of areas of the inner and outer horizon of a non-extremal solution coincides with the square of the moduli-independent area of the horizon of the extremal solution with the same charges.
