论文摘要
我们在数值上估计了几个两种vertex图的差异，这些图有助于洛伦兹EPRL旋转泡沫传播器的辐射校正。我们将幅度计算为在整体量子数，固定边界数据和不同的immirzi参数上均匀截止的函数，并发现对于一类两种vertex图的函数，那些内部面部较少面孔的函数是收敛的。计算是使用数值框架SL2CFOAM-NEXT完成的。
We numerically estimate the divergence of several two-vertex diagrams that contribute to the radiative corrections for the Lorentzian EPRL spin foam propagator. We compute the amplitudes as functions of a homogeneous cutoff over the bulk quantum numbers, fixed boundary data, and different Immirzi parameters, and find that for a class of two-vertex diagrams, those with fewer than six internal faces are convergent. The calculations are done with the numerical framework sl2cfoam-next.
