摘要

banks - fischer - shenker - susskind矩阵模型中的膜构型由于势中存在平坦方向而不稳定，其衰减过程可以看作是混沌散射的一种实现。在本文中，我们在简化模型中计算膜的寿命。所得寿命在能量、耦合常数和截止尺度方面表现出标度规律。我们对标度指数进行了数值计算，这是无法通过量纲分析确定的。最后，对结果的一些应用进行了讨论。

Scaling law for membrane lifetime

Membrane configurations in the Banks-Fischler-Shenker-Susskind matrix model are unstable due to the existence of flat directions in the potential and the decay process can be seen as a realization of chaotic scattering. In this note, we compute the lifetime of a membrane in a reduced model. The resulting lifetime exhibits scaling laws with respect to energy, coupling constant and a cut-off scale. We numerically evaluate the scaling exponents, which cannot be fixed by the dimensional analysis. Finally, some applications of the results are discussed.

期刊介绍： Nuclear Physics B focuses on the domain of high energy physics, quantum field theory, statistical systems, and mathematical physics, and includes four main sections: high energy physics - phenomenology, high energy physics - theory, high energy physics - experiment, and quantum field theory, statistical systems, and mathematical physics. The emphasis is on original research papers (Frontiers Articles or Full Length Articles), but Review Articles are also welcome.
