ATLAS reports that they have excluded Higgs with mass of 158-186 GeV but see an excess of between 2 and 3 standard deviations in the range 130-150 or so.

CMS reports exclusion of 150-183 but they see some excess in the same region of 130-150 or so, not quite as large, more like 1-2 standard deviations if my eyes do not deceive me.

This could be a badly modeled background, a statistical fluctuation, or the first sign of the Higgs particle.  More data needed.
