Papers by ATLAS and CMS have appeared in Physics Letters B and can be freely downloaded. They report on the discovery of the Higgs-like particle on July 4th.
CMS Collaboration (2012). Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC Physics Letters B DOI: 10.1016/j.physletb.2012.08.021
ATLAS Collaboration (2012). Combined search for the Standard Model Higgs boson using up to 4.9 fb^{−1} of pp collision data at \sqrt{7} TeV with the ATLAS detector at the LHC Physics Letters B DOI: 10.1016/j.physletb.2012.02.044
The Gauge Connection 
do not see any difference from the papers already published before..
Dear Anthony,
The difference with respect to preprints on arxiv is that now this discovery is carved in stone, being published on a refereed journal.
Marco
OK ! Thanks Marco
