Speed of LHC hadrons
Hi There is indeed at least one place on the CERN web site that says 99.99%c, but that is a slip up and not really correct, except that 99.99% is not so very different from 99.9999991%, in a certain sense. However, if you compute it correctly based on 7 TeV proton energy, you find that 99.9999991% really is right, and this same number appears elsewhere in the CERN documentation, so it is not WP:OR.

 * Of cause, I would agree with you if I consider proton mass m_p only. According to 3 page LHC has Pb Pb collision with only 2.76 TeV/n (per proton). It gives 99.999994 %. Alexander Mayorov (talk) 14:19, 30 October 2008 (UTC)
