I have read some recent preprints in arxiv recently:(adsbygoogle = window.adsbygoogle || []).push({});

about the behavior of the gluon propagator in the infrared. Recent lattice computations seem to support them (e.g. http://arxiv.org/abs/0710.0412) and the agreement with the spectrum of a pure Yang-Mills theory appears quite striking (e.g. http://arxiv.org/abs/hep-lat/0404008) with a proper choice of the string tension. I was not able to find any obvious fault in the mathematical derivations in these papers. In other times such a very good coincidences with the known results should have excited the community or some rumors should have been going around. Nothing of this happened. So, why?
