The paper is a good summary of a few of the topics that I find most interesting, but of course it is too incomplete to be advisable as a general read on the status of CMS. In any case, if you are interested you can download it here. Maybe here I can just produce a quote, forgiving myself for self-quoting (hey this is my blog after all): it is just the "Conclusions" section.
The CMS experiment has exploited the proton-proton collision data collected so far by the 2011 and 2012 runs of the Large Hadron Collider to produce a large number of groundbreaking results in precision measurements of standard model observables and searches for new physics. Among the most exciting of these results is certainly the observation of a new particle in the search for the Higgs boson ; the particle has a cross section compatible with that expected from a standard model Higgs, decays that imply its bosonic nature, and a mass of Mh = 125.3 ± 0.4(stat.) ± 0.5(syst.) GeV; it is expected that the full 2012 dataset will allow more definite conclusions on the nature of this new boson. Another striking conclusion one can draw from the set of produced results is that natural low-scale Supersymmetry is getting close to be excluded across the board of the wide SUSY parameter space; similarly, other exotics new physics models are nowhere to be seen in TeV-scale collisions.
