Ordinarily, the superpartners would be expected to have the same masses as their SM partners, so they would have been observed already but, via a spontaneous symmetry breaking process, the superpartners are imbued with higher mass. For each SM boson (photon, W or Z boson, Higgs), there is a corresponding supersymmetric fermion (photino, wino, zino, Higgsino). For each SM fermion (electron, neutrino, quark), there is a supersymmetric boson (selectron, sneutrino, squark). SUSY is a proposed approach to extending the Standard Model of Particle Physics in such a way that, for every particle in the Standard Model, there exists a corresponding supersymmetric partner particle of opposite spin type. Supersymmetry (or SUSY for short) is a concept conceived in the early seventies.
But perhaps I should first clarify what the heck it is. There was more analysis related to characterizing the Higgs discovery based upon more data, the observation of a new composite particle, observation of mixing, and, perhaps biggest at all, data which casts the body of theories known as supersymmetry into further doubt (or not: more on that in a bit). The results are perhaps not as earth-shaking as July’s announcement of the tentative discovery of the Higgs boson, but big nonetheless. Not only are they golden opportunities to network with colleagues from around the world, swapping phone numbers, email addresses, and ideas, but they are also prime opportunities to present results. Events such as this are a big deal for physicists. To see why, it might be fruitful to step back and take a look at the announcements from the last major conference like this.īack in November of 2012, theoretical and experimental particle physicists from around the globe, especially those involved with experiments at CERN‘s Large Hadron Collider, gathered in Kyoto, Japan to attend the Hadron Collider Physics Conference (HCP 2012). (Gamma-gamma counts were a bit high at that point, although still within error bars, and the rare tau-anti-tau signal had yet to be observed by CMS.) I don’t expect breakthrough-level announcements on this front just yet, as that will likely have to wait until more data is collected after the LHC upgrade, but the picture painted by the data collected thus far should start to grow a bit more clear as statistical fluctuations start to get dampened by larger and larger datasets.īut what I am really interested in seeing is news about supersymmetry (or SUSY for short).

(Keep in mind that, as of around Valentine’s Day, the LHC is offline until 2015 for repairs and upgrades.) While the Jannouncement was a major milestone, further data was still needed to verify that the newly-discovered boson is in fact a spin-0 boson (as opposed to a spin-1 boson such as a photon, W or Z boson, or spin-2 such as the hypothetical graviton), and whether the branching ratios for its decay products are as predicted by the Standard Model. The sessions from Wednesday, March 6 will be webcast, and are anticipated to include the latest results of analysis of data from CERN‘s Large Hadron Collider, including the latest info regarding the quest to determine whether the “Higgs-like boson” announced last July 4 is indeed the Standard Model Higgs boson. I would gladly part with a few organs to be there.) This high energy particle physics conference, which runs through March 14, gathers together some of the best and brightest experimentalists and theorists from the world of particle physics.
(La Thuile is smack-dab between Lyon, France and Milano, Italy, just southeast of Geneva, Switzerland. Yesterday, the 2013 installment of Rencontres de Moriond got underway at La Thuile, in the Aosta Valley of the Italian Alps, roughly where Italy, France, and Switzerland come together.
