The second infn school of statistics took place this week in the nice "green island" of Ischia, in the gulf of Naples, Italy. Organized by the INFN section of Naples, the school aims at training Ph.D. students and post-graduates in the foundations and the applications of the statistical methods most used nowadays in particle physics, nuclear physics, and astrophysics.

Yesterday I posed a question - Are the first collisions recorded by the LHC running at 13 TeV the highest-energy ever produced by mankind with subatomic particles ? It was a tricky one, as usual, meant to think about the matter.

I received several tentative answer in the comments thread, and thus answered there. I paste the text here as it is of some interest to some of you and I wish it does not go overlooked.


Dear all, 
The LHC has finally started to produce 13-TeV proton-proton collisions!

The picture below shows one such collision, as recorded by the CMS experiment today. The blue boxes show the energy recorded in the calorimeter, which measures particle energy by "destroying" them as they interact with the dense layers of matter that this device is made up of; the yellow curves show tracks reconstructed by the ionization deposits of charged particles left in the silicon detector layers of the inner tracker. 
The European Union has released some data on the latest call for applications for ITN grants. These are "training networks" where academic and non-academic institutions pool up to provide innovative training to doctoral students, in the meanting producing excellent research outputs.
