Thank you very much for your beautiful paper. It is a great news! Please, note that my paper with the answer to Terry Tao <a href="http://arxiv.org/abs/0903.2357" rel="nofollow">0903.2357</a> has gone published in Modern Physics Letters A. You can find the exact reference in the above link. You can also read an exchange with Terry <a href="http://tosio.math.toronto.edu/wiki/index.php/Talk:Yang-Mills_equations" rel="nofollow">here</a>. I was not able to convince him to plead for me but, as you can read, he consider my last proof correct. Your lattice computations are soundly confirming my findings and in a really striking and unexpected way. <strong>Mapping indeed exists</strong> and now it is not just a mathematical proof but you have seen it by numerically solving quantum field theory! It is interesting to note that the first authors to point out that Yang-Mills theory in d=2+1 has a tower of excitations were McKellar and Carlsson <a href="http://arxiv.org/abs/hep-lat/0303018" rel="nofollow">here</a> and <a href="http://arxiv.org/abs/hep-lat/0303022" rel="nofollow">here</a>. Since then, there have been several good works about all confirming this idea even if not explicitly as zeros of Bessel functions that, indeed, in some limit recover the harmonic oscillator spectrum. Please, take my best greetings to Attilio e Tereza. They must keep up with their excellent work as longer as possible. Thank you very much again. I will take some time to write about this in a post. Best, Marco Dear Rafael,

I worry that supersymmetry is preventative medicine against divergences and whether that is a good reason for particles to exist. It is always fun when a theory predicts a particle for the wrong reasons. Einstein said that Nature is not unkind, but that was before quarks. Thanks.

I can only give you some educated guesses. I would expect to see Higgs particles popping out somewhere in their detectors. Surely, after a few time people will be running LHC, we will finally know how masses are generated in the Standard Model. It could happen that such Higgses are supersymmetric and this will be a double strike we are hoping for. For other possibilities I cannot say more. Surely, seeing a black hope evaporating around will earn a Nobel to Hawking and we will finally have a first direct evidence of quantum gravity. Just a matter of time, not much time. Be patient. Marco Dear jr,

After all it does contain the SU(3) being hauled around by protons and might be more plausible than black holes and all that. just wondering if the LHC will bump into evidence of
