我们讨论了照片蒙特卡罗算法的精度，并改进了QED干涉和多光子辐射的实现。照片的主要应用是在任何共振的衰变过程中产生QED辐射校正，这是由“主机”蒙特卡罗发生器模拟的。在专门为此目的定制的MC-TESTER工具的帮助下，通过仔细的自动比较，我们发现，在Z和W衰变的情况下，当前版本的照片的精度为0.1%。在一般情况下，照片的精度也有所提高，但这一点在这里不会量化。
We present a discussion of the precision for the PHOTOS Monte Carlo algorithm, with improved implementation of QED interference and multiple-photon radiation. The main application of PHOTOS is the generation of QED radiative corrections in decays of any resonances, simulated by a "host" Monte Carlo generator. By careful comparisons automated with the help of the MC-TESTER tool specially tailored for that purpose, we found that the precision of the current version of PHOTOS is of 0.1% in the case of Z and W decays. In the general case, the precision of PHOTOS was also improved, but this will not be quantified here.
