    About Tommaso

    I am an experimental particle physicist working with the CMS experiment at CERN. In my spare time I play chess, abuse the piano, and aim my dobson...

    Let me write here a short note -just for the record- to mention a proceedings paper I wrote for the ICFP 2012 conference. I spoke in Crete last June about the latest results of the CMS experiment, but in the meantime a lot happened -the Higgs boson discovery, just to mention one thing. So this writeup includes the new measurements of Higgs boson cross section, mass, and properties that the CMS experiment has produced since last July, as well as selected results in top and electroweak physics, searches for rare B decays, and new physics searches.

    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 [42]; 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.
