我们研究了外加电场在N=4超对称杨-米尔斯理论的库仑支上产生W玻色子的隧道对。我们利用ADS/CFT全息术找到了Schwinger公式在强耦合平面极限下的推广，它包含了虚拟无质量粒子到所有阶的交换。我们发现，对产生公式有一个较高的临界电场，超过这个电场，该过程不再被指数抑制。临界场的大小与ADS(5)×S(5)背景中D3-膜的Born-Infeld作用的临界值相同，其中AdS(5)和S(5)分别是5维反德西特空间和5维球面。
We study tunneling pair creation of W bosons by an external electric field on the Coulomb branch of N=4 supersymmetric Yang-Mills theory. We use AdS/CFT holography to find a generalization of Schwinger's formula for the pair production rate to the strong coupling, planar limit which includes the exchange of virtual massless particles to all orders. We find that the pair creation formula has an upper critical electric field beyond which the process is no longer exponentially suppressed. The value of the critical field is identical to that which occurs in the Born-Infeld action of probe D3-branes in the AdS(5)×S(5) background, where AdS(5) and S(5) are 5-dimensional anti-de Sitter space and the 5-sphere, respectively.
