我们使用Randall-Sundrum模型作为扭曲额外维度的原型来研究大额外维度对黑洞种子真空衰变的影响。我们用潮汐解建立了膜世界黑洞模型，并求解了膜上瞬子的希格斯运动方程。值得注意的是，静态瞬子的作用可以被证明是种子黑洞和残余黑洞的体积面积的差异，我们估计这些面积假设黑洞与体积反德西特半径相比是小的。与霍金蒸发速率的比较表明，小黑洞种子优先催化真空衰变，从而将我们之前的结果扩展到更高维度的膜世界场景。该参数范围不允许标准模型的希格斯衰变从对撞机黑洞中产生，但它们可能与宇宙射线碰撞有关。
We examine the effect of large extra dimensions on black hole seeded vacuum decay using the Randall-Sundrum model as a prototype for warped extra dimensions. We model the braneworld black hole by a tidal solution and solve the Higgs equations of motion for the instanton on the brane. Remarkably, the action of the static instanton can be shown to be the difference in the bulk areas of the seed and remnant black holes, and we estimate these areas assuming the black holes are small compared to the bulk anti–de Sitter radius. Comparing to the Hawking evaporation rate shows that small black hole seeds preferentially catalyze vacuum decay, thus extending our previous results to higher-dimensional braneworld scenarios. The parameter ranges do not allow for standard model Higgs decay from collider black holes, but they can be relevant for cosmic ray collisions.
