标题： Mixed five-point correlators in the 3d Ising model

摘要： 我们研究临界3d伊辛模型中$\sigma$、$\epsilon$和$\epsilon'$算符的五点关联函数。 我们考虑$\sigma \times \sigma$和$\sigma \times \epsilon$的算符乘积展开（OPE），并通过包含一组有限的交换算符来截断它们。 我们通过适当不相连的五点关联函数中的相应贡献来近似截断后的算符。 我们计算了一些之前未知的OPE系数，并表明这些系数与使用临界3d伊辛模型的模糊球正则化方法获得的预测一致。 显示英文摘要

摘要： We study five-point correlators of the $\sigma$, $\epsilon$, and $\epsilon'$ operators in the critical 3d Ising model. We consider the $\sigma \times \sigma$ and $\sigma \times \epsilon$ operator product expansions (OPEs) and truncate them by including a finite set of exchanged operators. We approximate the truncated operators by the corresponding contributions in appropriate disconnected five-point correlators. We compute a number of OPE coefficients that were previously unknown and show that these are consistent with predictions obtained using the fuzzy sphere regularization of the critical 3d Ising model.
