作为原始黑洞源的致密额外维

Compact extra dimensions as the source of primordial black holes

Valery V. Nikulin, Maxim A. Krasnov, Sergey G. Rubin

摘要:

讨论了再加热阶段原始黑洞形成的模型。这些小而重的黑洞的出现是由于致密额外维度的特殊性质。后者给出了包含有效标量场势的低能模型,该模型能够产生畴壁。这些墙是在通货膨胀期间形成的,非常致密,因此在通货膨胀结束后很快就会倒塌。讨论是在多维$f(R)$-重力的范围内进行的。

英文摘要:

We discuss the model of the primordial black holes formation at the reheating stage. These small massive black holes appear due to specific properties of the compact extra dimensions. The latter gives rise the low energy model containing the effective scalar field potential capable for the domain walls production. Formed during inflation, these walls are quite dense so they collapse soon after inflation ends. The discussion is performed within the scope of multidimensional $f(R)$-gravity.
