具有四个分支和无限多个环路的指数抑制
Exponential suppression with four legs and an infinity of loops
摘要：
无质量φ ^[3]理论的L-圈四点梯形图在所有四条腿都离壳时是有限的，并且是用阶数从L到2L的多项式给出的。我们得到的线性戴森-施温格方程的精确解，总结这些梯形图，并表明，这个总和指数快速消失在强耦合。
英文摘要：
The L-loop 4-point ladder diagram of massless phi^3 theory is finite when all 4 legs are off-shell and is given in terms of polylogarithms with orders ranging from L to 2L. We obtain the exact solution of the linear Dyson-Schwinger equation that sums these ladder diagrams and show that this sum vanishes exponentially fast at strong coupling.
