Perhaps a bit too simple, but certainly appealing. Extensions of the Standard Model which imply the existence of a new U(1) gauge group to complement the SU(2)xU(1) structure of electroweak interactions have been put forth in a number of slightly different versions. All imply the existence of a new Z' boson, a heavier version of the Z0. For those not yet introduced to the latter, the Z0 is the neutral vector boson hypothesized by Glashow, Salam and Weinberg in the sixties to complete a triplet of weak currents and thereby allow the unification of weak and electromagnetic interactions.

Little less than one year ago the world of fundamental physics was shaken by the bold claim of the OPERA collaboration, which produced a measurement of the time of flight of neutrinos traveling underground from Geneva to the Gran Sasso mine in central Italy. The beam of neutrinos, produced by the CERN SpS proton synchrotron, was observed to produce interactions in the large mass of the OPERA detector with about 60 nanosecond anticipation with respect to what would be expected for a particle traveling at exactly the speed of light (2439096.1+-0.3 nanoseconds, since the flight path is of 731221.95+-0.09 meters).

The Large Hadron Collider is delivering as expected a large amount of integrated luminosity of proton-proton collisions to CMS and ATLAS, running at a centre-of-mass energy of 8 TeV. The total collected in 2012 by CMS has just now crossed the mark of 10 inverse femtobarns: this is twice as much data as that collected in 2011. And the CMS detector is working like a charm, with all subsystems collecting data flawlessly.

Physicists need large integrated luminosity to explore rare phenomena, and high energy to probe processes which may only "turn on" above a certain threshold. So given the x2 luminosity so far collected (but we will get to x5 by the end of the year!) and x1.14 energy, the discovery potential of 2012 data is already several times larger than that of 2011 data.

I am very happy to have been invited, by Matteo Polettini, to two events that will take place at Festivaletteratura (literature festival), an important cultural event that takes place in Mantova, a beautiful town in northern Italy, from the 5th to the 9th of September.

ATLAS has just released a note which summarizes the searches for the standard model Higgs boson in 7-TeV and 8-TeV data. Since July 4th the main improvement is the addition of the WW channel, which had not been shown back then. With it, the combined local significance of the 126 GeV Higgs boson excess in the WW, ZZ, and γγ channels grows to 5.9 standard deviations. In the words of a Facebook friend who's in ATLAS: "if this is not a discovery, I don't know what is".
